- Distribution CenterA facility that receives inbound goods, holds inventory for short periods, and prepares outbound orders for stores, wholesalers, or consumers. Core functions include receiving, putaway, slotting, picking, packing, and shipping, supported by a warehouse management system and material handling equipment. Many sites also perform value added services such as labeling, kitting, light assembly, and returns processing. It differs from a warehouse that primarily provides longer term storage.
- Dock SchedulingThe process of planning and managing truck appointments at a facility’s loading docks. It allocates doors and time windows for inbound and outbound loads, records appointments, sequences arrivals and departures, and coordinates check in, door assignment, live unload or drop trailer, and check out. Dock scheduling systems often integrate with warehouse, transportation, and yard management to apply constraints such as door compatibility, dock capacity, equipment availability, load type, service time, and labor schedules, while tracking status from arrival to departure.
- DrayageShort distance ground transport of ocean or intermodal containers between locations such as a port, rail ramp, container yard, warehouse, or distribution center. It includes picking up a loaded container, moving it to a nearby facility, and returning the empty or an export load, as well as terminal transfers between yards or modes. Carriers bill drayage as a separate charge from linehaul and it is often used to connect port or rail arrivals with the next leg of a shipment.
- Drop ShippingDrop shipping is a retail fulfillment method where a seller does not keep the products it sells in stock. Instead, when a customer places an order, the seller forwards the order details to a supplier (such as a manufacturer or wholesaler), who then ships the product directly to the customer. In this arrangement, the retailer acts as an intermediary and does not handle or store the goods. The items bypass the retailer’s warehouse entirely, with order fulfillment handled by the supplier.
- Drop TrailerA trailer left by a motor carrier at a shipper or consignee for loading or unloading without the driver waiting. The tractor disconnects and departs, then the same or another tractor returns to retrieve the trailer when it is ready. Drop trailer programs often use trailer pools and yard management controls and are common in truckload moves. Related term drop and hook refers to picking up a preloaded trailer while leaving an empty.
- Dry VanAn enclosed, non refrigerated box trailer used to transport general freight by road. It shields cargo from weather and road debris and typically loads through rear doors at a dock or with a liftgate. In North America a common length is 53 feet. It is not used for temperature controlled goods, liquids, or oversized loads.
- DunnageProtective materials placed around, between, or under cargo to prevent movement and damage during transport, handling, or storage. It fills voids, braces and cushions loads, and can separate layers or distribute weight. Common forms include inflatable bags, foam, corrugated cardboard, wood blocking, pallets, pads, and edge protectors. Dunnage may be single use or reusable and is selected to match the mode, packaging, and load weight.
- Duty DrawbackA customs program that refunds some or all import duties, taxes, and eligible fees when imported goods are later exported, destroyed under customs control, or used as inputs in products that are exported. Requirements and refund levels vary by jurisdiction and typically require documented linkage between the import and the export.
e
- E-FulfillmentProcessing online orders from receipt to handoff to a carrier. It covers order capture from ecommerce platforms, inventory storage, pick and pack, shipping label creation, and parcel dispatch. Systems commonly sync tracking updates and handle returns so items can be received, inspected, and restocked.
- EcommerceBuying and selling goods or services over the internet through online stores, marketplaces, and business portals. It includes product browsing, pricing, checkout, payment processing, tax calculation, and order confirmation. Operations link to inventory, customer accounts, and fulfillment systems for shipping or digital delivery.
- Ecommerce FulfillmentThe process of completing an online order from inventory to delivery. It includes receiving and storing stock, order allocation, picking, packing, parcel labeling, carrier handoff, and delivery confirmation. It may also cover kitting, inserts, and returns processing, and can be handled in house or by a third party provider.
- Ecommerce IntegrationThe technical connection that links an online store to other systems and automates data exchange. It connects shopping carts and marketplaces with enterprise resource planning ERP, warehouse and order management systems WMS and OMS, payment processors, and carrier systems, synchronizing orders, inventory, product catalog, pricing, shipping labels, tracking, and returns through application programming interfaces APIs, webhooks, or electronic data interchange EDI.
- Ecommerce Laws and RegulationsLegal requirements that govern online buying and selling across domestic and cross border markets. They cover consumer rights and disclosures, returns and refunds, data privacy and security, electronic contracts and signatures, taxes including sales tax and VAT, payment processing and anti money laundering rules, advertising and email rules, product safety and labeling, restricted goods, shipping terms, customs and export controls, intellectual property, accessibility, and recordkeeping. Specific obligations and enforcement bodies vary by country and industry.
- Ecommerce PackagingPackaging designed for goods shipped directly to consumers through parcel carriers. It covers the outer container such as boxes or mailers, internal cushioning, closures, and shipping labels. Specifications address product protection, carrier handling, and size and weight rules including dimensional weight. Many programs add tamper evidence and return materials or instructions.
- Ecommerce ShippingThe process of moving online orders from a seller or fulfillment center to the customer. It covers service selection and rate calculation based on weight, dimensional weight, size, destination, and speed, creation of shipping labels, carrier handoff, tracking and delivery confirmation, and return shipment handling. Cross border shipments require customs data and duty or tax processing.
- Economic Order Quantity (EAQ)A formula that sets the order size for a single item that minimizes the combined cost of placing orders and holding inventory. The classic model assumes constant demand and lead time, a fixed cost per order, a constant unit price, no stockouts, and one stocking location. Formula Q* equals the square root of 2 D S divided by H, where D is demand per period, S is ordering cost per order, and H is holding cost per unit per period.
- EDI MappingThe specification that defines how fields in an EDI transaction set correspond to data in a sender or receiver system, including segment order, loops, qualifiers, and allowed codes. A mapping details translation rules for formats, units, dates, default values, and cross references, and captures partner specific requirements for X12 850, 856, 810 and EDIFACT messages. It also sets validations and required acknowledgments such as 997 or CONTRL.
- Electronic Data Interchange (EDI)The structured, machine readable exchange of business documents between trading partners using agreed standards and protocols. EDI carries transaction sets such as 850 purchase order, 856 advance ship notice, and 810 invoice in formats like ANSI X12 or UN EDIFACT, with envelopes, segments, qualifiers, and control numbers. Messages are sent via AS2, SFTP, or value added networks, with functional acknowledgments such as 997 or CONTRL and trading partner agreements that define formats, codes, and timing.
- Estimated DeliveryA projected arrival date or window for a shipment, shown at checkout and on tracking pages. The estimate is calculated from carrier service standards, selected shipping method, cutoff and handling times, distance between origin and destination, weekends and holidays, and any required customs processing. It is an informational forecast and can change based on transit events.
- Expedited ShippingA carrier service level that accelerates delivery compared with standard shipping through priority handling, faster modes such as air or express ground, and time definite routing. Offered as next day, two day, or same day services. Typically priced higher and may include earlier order cutoff times, size or weight limits, and limited service areas.
- Export LicenseA government authorization that permits the export, reexport, or transfer of specified goods, software, or technical data to a named foreign destination. It is required when the item, end use, end user, or destination is controlled by law. The license lists the approved parties, destination, classification, quantities, validity period, and conditions, and is reviewed during carrier and customs screening. It is issued by a national export control authority and is separate from routine shipping documents.
- Export TariffA tax imposed by a government on goods when they leave the country. It is assessed by customs during export clearance and is usually calculated either as a percentage of the shipment value free on board or as a fixed charge per unit or weight. Rates and coverage are set in the national tariff schedule by product code such as the HS code. It differs from an import tariff, which applies to goods entering a country.
f
- Fca Free CarrierAn Incoterms rule in which the seller delivers goods, cleared for export, to the carrier or another party named by the buyer at a specified place. Risk transfers to the buyer when the goods are handed over at that point. If delivery is at the seller’s premises, the seller loads the goods. If delivery is at another place, the seller presents the goods and the buyer handles unloading. FCA applies to any mode of transport, and the buyer arranges main carriage and insurance.
- Fcl Full Container LoadA shipment in which one shipper books a container for exclusive use from origin to destination. The container is packed and sealed at origin, moved as a single unit through port and inland transport, and opened at destination. Charges are quoted per container rather than by volume, and documents typically list one shipper and one consignee. Contrasts with LCL, where space is shared among multiple shippers.
- Fill RateA service level metric that shows the share of demand satisfied from on hand inventory without backorders or later shipments. Common formula is units shipped on first release divided by units ordered, expressed as a percentage. Variants include order fill rate, line fill rate, and case fill rate, applied to whole orders, individual order lines, or cases. Higher values reflect fewer stockouts at the time of order.
- First in First Out (FIFO)An inventory valuation and stock rotation approach in which the earliest acquired units are recorded as used or sold first. In accounting, cost of goods sold is priced using the oldest unit costs, and ending inventory reflects more recent purchase or production costs. In warehousing, it is a picking rule that moves older dated lots before newer ones.
- Flat Rate ShippingA carrier pricing option that charges one fixed fee for a parcel that fits a specified box or size tier, regardless of destination zone or weight up to the program limit. The carrier defines eligibility rules such as acceptable contents, maximum weight, and required packaging. Optional services and surcharges are billed separately.
- Flow ForecastingThe projection of the volume, mix, and timing of goods, orders, and shipments moving through a facility or network over a defined period. Built from transaction history and current plans, it estimates inbound receipts, work in process, and outbound demand by time interval to support scheduling of labor, space, and transportation capacity.
- Flow Through DistributionA distribution approach where goods pass through a facility with little or no storage, moving from receiving to outbound staging in a short window. Inbound loads are deconsolidated and sorted to destinations or orders, sometimes with light handling such as labeling or case breaking, then loaded to outbound carriers the same day or next day.
- Fob Free on BoardAn Incoterms rule for sea and inland waterway shipments where the seller delivers and risk transfers once goods are loaded on the buyer nominated vessel at the named port of shipment. The seller handles export packaging, transport to the port, export clearance, and loading on board. The buyer selects the carrier and pays ocean freight, insurance if purchased, and import clearance and duties. Under Incoterms guidance, FOB is intended for non containerized cargo, while FCA is often used for container shipments.
- Forecast AccuracyA metric that quantifies how closely predicted demand matches actual demand over a defined period. Reported as a percentage, often calculated as one hundred percent minus mean absolute percentage error, or derived from error measures such as mean absolute error or root mean squared error. Results can be reported by product, location, and time bucket to assess forecasting performance against observed outcomes.
- Foreign Trade Zone FtzA designated site in the United States treated as outside U.S. customs territory for duty assessment, authorized by the FTZ Board and supervised by Customs and Border Protection. Merchandise may be admitted to store, inspect, relabel, assemble, or manufacture without formal customs entry, with duties and certain taxes deferred until goods enter domestic commerce. Inverted tariff treatment can apply, and goods reexported from the zone generally incur no U.S. duty, subject to customs control and recordkeeping requirements.
- Fourth Party Logistics 4PLA supply chain integrator that designs, coordinates, and oversees end to end logistics using multiple third party providers and carriers. A 4PL serves as a single point of contact, managing provider selection, contracts, service levels, and data integration across transportation, warehousing, and fulfillment. It typically operates without owning physical assets and runs a control tower for network monitoring, planning, and exception handling. Unlike a 3PL that executes specific operations, a 4PL orchestrates and governs those operations across providers.
- Free TimeThe period allowed by a carrier, port, rail ramp, or warehouse during which containers, trailers, or cargo may remain at a facility or on hired equipment without storage, demurrage, or detention charges. Contract terms or tariffs define when the clock starts and stops, how days are counted, and where it applies. After free time ends, the relevant fees accrue until the unit is picked up, returned, or released.
- Freight AlignmentThe process of matching a shipper’s freight profile to carriers, modes, and lanes that can meet its volumes, equipment needs, service levels, and pickup and delivery windows. It relies on lane level data such as origin and destination pairs, shipment frequency, weight and cube, commodity and packaging, and any special handling or accessorial requirements. The output is a routing guide with volume allocations, contract terms, and primary and backup carriers for defined lanes.
- Freight AuditA review of carrier invoices to confirm charges match contracted rates, tariffs, and shipment details. It validates lanes, mode, weight and dimensions, service level, fuel and accessorials, taxes, currency, and supporting documents such as proof of delivery, while checking for duplicates and misclassifications. Audits may occur before payment pre audit or after payment post audit. The output is approved bills, exceptions for dispute or correction, and coded data for payment, cost allocation, and reporting.
- Freight BiddingA competitive process where shippers request price and service offers from carriers or brokers for defined lanes, volumes, and service levels. Bids are gathered via request for proposal or spot events and assessed on rates, capacity commitments, transit time, equipment, accessorial terms, and compliance. Awards assign freight to selected providers for a set period or specific loads, documented in rate sheets or contracts.
- Freight BrokerageA service that connects shippers with authorized carriers and arranges transportation without owning the trucks or other assets. Brokers source capacity, negotiate rates, verify carrier qualifications and insurance, tender and track loads, and handle documentation, billing, and claims. Compensation is typically the difference between the shipper rate and the carrier payment or a stated fee.
- Freight CarrierA company that transports cargo for hire by road, rail, air, or sea. It operates the conveyance, holds any required authority, accepts custody of freight, and is legally responsible for carriage under documents such as a bill of lading or air waybill. Carriers can be common or contract and may focus on parcel, less than truckload, full truckload, intermodal, or ocean shipping, providing pickup, linehaul, and delivery.
- Freight ClaimsA formal demand to a carrier for monetary compensation related to cargo loss, damage, shortage, delay, or billing errors during transportation. Claims may be filed by the shipper, consignee, or an assignee and rely on the bill of lading, delivery receipts, and supporting proof such as invoices, photos, and inspection reports. Liability rules, filing deadlines, and documentation requirements are set by the carriage contract, tariffs, and applicable laws, and they vary by mode and jurisdiction.
- Freight ClassA standardized rating used in United States less than truckload shipping that groups commodities by transport characteristics to set rates and rules. Classes run from 50 to 500. Assignment considers density, handling, stowability, and liability. Each commodity links to an NMFC item number used for pricing and claims.
- Freight ConsolidationThe practice of combining multiple smaller shipments into a single larger load moved under one linehaul to a shared destination or hub. Shipments can originate from one shipper across orders or from several shippers with compatible lanes. Consolidation takes place at a cross dock or forwarder facility and is followed by deconsolidation for final delivery. It is common in trucking such as LTL pool programs and in ocean moves where LCL cargo is grouped, often under one bill of lading for the consolidated leg.
- Freight ConsolidatorA logistics provider that aggregates smaller shipments from one or more shippers into a single move for a shared route or destination. The consolidator receives cargo at a cross dock or container freight station, builds the linehaul load such as pooled LTL, air freight pallets, or LCL ocean containers, and issues house bills tied to a master bill of lading or master air waybill for the consolidated leg. Responsibilities include arranging pickup, scheduling the linehaul, managing deconsolidation at the destination facility, and releasing freight to final mile carriers.
- Freight FactoringA financing arrangement in which a carrier or freight broker sells freight invoices to a third party factor at a discount for immediate payment. The factor advances a percentage of the invoice value and releases the remainder, minus fees, when the payer remits. Risk of nonpayment depends on contract type where recourse requires the client to repurchase unpaid invoices and non recourse places approved credit risk with the factor. Transactions rely on valid bills of lading and proof of delivery and often include credit checks and collections handled by the factor.
- Freight ForwarderA logistics intermediary that plans and arranges shipments for a shipper. Tasks include selecting and booking carriers, routing across modes, consolidating cargo, preparing transport and trade documents, coordinating customs clearance through licensed brokers, and arranging cargo insurance. Forwarders often issue house bills of lading. Unless they operate as a carrier such as an NVOCC or as an air cargo agent, they act as the shipper’s agent rather than the carrier of record.
- Freight ForwardingThe service of planning and arranging the movement of goods on behalf of a shipper across domestic or international legs. It covers rate quoting, carrier selection and booking, routing across modes, cargo consolidation, preparation of transport and trade documents, coordination of customs clearance through licensed brokers, and arrangement of cargo insurance and final delivery. In most cases the forwarder acts as the shipper’s agent and may issue a house bill of lading while underlying carriers transport the freight.
- Freight Invoice AuditA review of carrier invoices to confirm that billed charges match contracted rates and the actual shipment. The audit compares lane, mode, weight or class, dimensions, distance, fuel and accessorial fees to the bill of lading, shipment tender, and proof of delivery. It identifies duplicates and rating errors, applies taxes and surcharges as specified, allocates costs to accounts or cost centers, and results in approval or dispute before payment.
- Freight OptimizationThe analytic process of planning shipments to minimize total transportation cost while meeting service, capacity, and regulatory constraints. It selects mode and carrier, builds loads, consolidates orders, sequences stops, assigns time windows, and balances weight and cube across trailers or containers using rates, transit times, and available capacity. Results include tender plans, routing guides, dock schedules, and performance measures such as cost per shipment, on time pickup and delivery, and equipment utilization.
- Freight Rate ManagementThe administration of carrier pricing across lanes and modes, from sourcing to daily use. It includes gathering and negotiating tariffs and contracts, normalizing file formats, loading rates into a rating engine or a transportation management system, and maintaining rules for fuel, accessorials, minimums, currencies, and validity periods. It also covers invoice auditing against contracted terms, tracking general rate increases, and updating routing guides so shipments are priced according to the agreed schedule.
- Freight ReleaseAuthorization from a carrier or its agent that all freight charges for a shipment have been paid and required documents are in order, allowing the cargo to be made available to the consignee. In ocean transport, it follows validation of the bill of lading and payment and may be issued as a telex release or express release, enabling a delivery order. Once the release is recorded, the terminal or warehouse can permit pickup or interchange to the next carrier.
- FTLA trucking mode in which one shipper reserves an entire trailer for a single pickup and a single delivery. Shipments typically move direct from origin to destination rather than through terminals, with capacity limited by trailer weight, cube, or linear feet. Pricing is often quoted by lane or miles with a fuel surcharge, and equipment includes dry van, refrigerated trailer, and flatbed.
- Fuel SurchargeAn additional fee on a freight bill that reflects changes in fuel prices. It is usually linked to a public fuel price index, updated on a stated schedule, and applied as a percentage of the linehaul rate or as a per mile or per shipment amount. The trigger level, formula, and update method are defined in the tariff or contract.
- FulfillmentThe process of completing an order from receipt to delivery. It includes order capture, inventory allocation, picking, packing, labeling, documentation, carrier booking, and shipment handoff with tracking updates and proof of delivery. It can also include returns processing, exchanges, and value added steps such as kitting or gift packing, performed in a warehouse, store, or third party facility.
- Fulfillment By Amazon (FBA)An Amazon service where third party sellers send products to Amazon fulfillment centers. Amazon stores inventory and manages marketplace orders, including picking, packing, labeling, carrier booking, shipping, tracking updates, customer service, and returns. Sellers create inbound shipments and must meet prep and packaging rules. Fees include storage and per unit fulfillment charges, with possible surcharges for aged or peak storage. Inventory may qualify for Prime and can also be used to fulfill non Amazon orders through Multi Channel Fulfillment.
- Fulfillment By Merchant (FBM)An Amazon arrangement where the seller stores inventory and ships marketplace orders from its own facility or a non Amazon third party provider. The seller manages order processing, picking, packing, labeling, carrier selection, tracking updates, and returns. The account must meet Amazon requirements for order confirmation, on time shipment, valid tracking, and customer service metrics. Marketplace fees apply, while storage and fulfillment costs are borne by the merchant or its provider rather than Amazon.
- Fulfillment CenterA distribution facility that receives inbound goods, stores inventory, and processes customer orders. Core tasks include inventory control, order allocation, picking, packing, labeling, documentation, and handoff to parcel or freight carriers. Many sites also handle kitting, light assembly, personalization, and returns. Systems typically integrate with commerce and order management platforms to synchronize stock levels and transmit tracking data.
- Fulfillment CompanyA third party logistics provider that receives goods, stores inventory, and ships customer orders for another business. Core work includes inbound receiving and putaway, inventory control, order picking and packing, labeling, documentation, carrier handoff, and returns processing. Many also offer value added services such as kitting, light assembly, customization, and retailer compliance prep. Systems connect with ecommerce platforms, marketplaces, and order management tools to import orders, sync stock levels, and transmit tracking details.
- Fulfillment ServicesA set of operations that receive goods, store inventory, process orders, and hand off parcels or freight to carriers. Activities commonly include inbound receiving and putaway, inventory control, order picking and packing, labeling, documentation, carrier selection, shipment processing, and returns handling. Many providers also perform value added work such as kitting, light assembly, custom packaging, and retailer compliance preparation. Systems connect with ecommerce platforms and order management tools to import orders, update stock levels, and share tracking data.
g
- Geofencing in LogisticsThe use of GPS or cellular location data to set a virtual boundary around a site, route segment, or region. When a truck or asset crosses the boundary, the system records the event and can trigger actions such as arrival and departure timestamps, status updates to transportation or warehouse management systems, driver notifications, gate access control, and proof of service logs. Common applications include route adherence, yard and dock scheduling, detention time tracking, security alerts, and customer ETA updates. Geofence event data supports audits and performance metrics such as on time delivery and dwell time.
- Global FulfillmentThe coordination of warehousing, order processing, and delivery across multiple countries. It covers inventory placement in regional facilities, order routing to the nearest site, cross border shipping, customs documentation with HS codes, and duty and tax calculation using DDP or DAP terms. Related tasks include selecting local carriers, meeting country specific labeling and data requirements, validating international addresses, screening restricted goods, and handling returns across borders.
- Goods HandlingThe organized movement, storage, and preparation of goods within warehouses and transport hubs. It covers unloading and receiving, putaway, internal transfer, picking, packing, loading, and dispatch, with inspection, labeling, and documentation at each step. Work follows handling instructions and legal rules for weight, packaging, hazardous materials, and product identification, using equipment such as forklifts, pallet jacks, conveyors, and barcode or RFID scanning.
- Green LogisticsThe planning and operation of transportation, warehousing, and distribution to reduce environmental impact. It includes measuring and managing fuel use and emissions, selecting lower impact modes and routes, running energy efficient facilities, using reusable or recyclable packaging, handling waste and returns responsibly, and meeting environmental regulations and reporting requirements.
- Gross WeightThe total weight of a shipment, including the goods and all packaging and handling units such as inner packs, cartons, pallets, crates, and dunnage. It equals net weight plus tare weight. Carriers and customs record gross weight on shipping documents to apply weight limits and calculate charges.
- Ground ShippingThe movement of parcels or freight over land by truck or rail through parcel, less than truckload, and full truckload networks. Carriers quote time in business days and operate on scheduled routes. Pricing reflects weight, dimensions, distance, and service level, with dimensional weight used for many parcel shipments and class or density used for LTL. Cross border moves require customs documentation.
h
- Hazard Analysis and Critical Control Points (HACCP)A structured food safety system that identifies biological, chemical, and physical hazards across production, storage, and distribution. It designates critical control points where hazards can be prevented, eliminated, or reduced to an acceptable level, with defined limits, monitoring, corrective actions, verification, and recordkeeping. HACCP is used by food manufacturers, warehouses, and carriers to control contamination risk throughout the supply chain.
- HazmatShort for hazardous materials, goods that pose risk to health, safety, property, or the environment during storage or transport. These items are classified by hazard type and quantity and are subject to transport regulations governing packaging, labeling, placarding, documentation, segregation, and trained handling across all modes.
- HS CodeAn international product classification system maintained by the World Customs Organization. It assigns a six digit base code arranged by chapters, headings, and subheadings, which many countries extend with extra digits for national tariffs and statistics. HS codes are used on customs documents to identify goods, determine duty rates, apply trade controls, and compile trade data. The nomenclature is reviewed and updated on a regular cycle.
- HTS CodeThe United States tariff classification for imported goods that extends the Harmonized System to ten digits. The first six digits mirror the HS structure of chapters, headings, and subheadings, and the remaining digits are United States specific for duty rates and statistical reporting. HTS codes are required on import entries and used to classify goods, assess duties, apply quotas and trade remedies, and generate trade statistics. The schedule is published by the United States International Trade Commission and updated periodically.
- Hub and Spoke DistributionA network design that routes shipments through a central hub facility where goods from multiple origins are received, sorted, consolidated or deconsolidated, and dispatched to regional facilities or final destinations called spokes. It concentrates long haul moves between the hub and uses shorter local legs for pickup and delivery, common in parcel, less than truckload, and air cargo operations.
i
- Import LicenseAn official authorization issued by a government agency that permits a named importer to bring specified goods into a country. It typically lists the importer and seller, product description and tariff classification, country of origin, quantity or value limits, and a validity period, and may be single use or multiple use. Licenses are required for regulated or restricted items such as pharmaceuticals, chemicals, agricultural goods, weapons, and products subject to quotas or sanctions before customs release.
- Import QuotaA legal cap on the quantity or value of a specified product that may be imported during a defined period. The limit is set by tariff classifications and measured in units such as pieces, weight, volume, or declared value. Quotas may be global across all origins or allocated by exporting country. Administration can include quota licenses or certificates and tariff rate quotas, where a set amount enters at one duty and volumes above it face a higher duty. Customs enforces the cap at entry.
- In House FulfillmentA fulfillment model where a retailer or brand performs warehousing and order handling itself rather than using a third party logistics provider. It covers receiving and storing inventory, maintaining stock records, picking and packing orders, printing shipping labels, tendering shipments to carriers, managing returns, and related recordkeeping. Operations use the company’s own space, staff, and systems, including compliance with packaging, carrier, and documentation requirements.
- Inbound LogisticsThe planning, coordination, and control of goods moving from suppliers to a warehouse, plant, or fulfillment center. It includes purchase order management, carrier selection and routing, appointment scheduling, international paperwork and customs clearance when required, transport and delivery, receiving, unloading, inspection and discrepancy handling, putaway, and updates to inventory systems.
- IncotermsStandard trade definitions published by the International Chamber of Commerce used in international and domestic sales contracts. They specify the named place of delivery, the point where risk transfers, which party arranges and pays for transport, export and import clearance, insurance when a rule requires it, and required documents. Examples include EXW, FOB, CIF, and DDP. Incoterms allocate costs and risk but do not set price, transfer ownership, or dictate payment terms.
- Intermodal DrayageTruck transport that moves ocean or rail containers over short distances between nodes in an intermodal move, for example from a port or rail ramp to a warehouse or another carrier. It uses ISO containers on a chassis and may include pickup, live unload or drop, and the return of the container and chassis or an empty to a designated terminal. Timing follows gate hours, appointments, and rail or vessel cutoffs, and charges can include free time, detention, and demurrage under carrier and terminal rules.
- Intermodal ShippingMovement of freight in one continuous route using two or more transportation modes without unloading the cargo itself. Transfers occur at terminals using standardized containers or trailers across truck, rail, and ocean. Shipments are documented under a single or linked bill of lading, with charges that may include linehaul, drayage, and terminal handling. Tracking uses equipment identifiers such as container numbers and chassis identifiers during handoffs.
- Intermodal TransportationCoordinated movement of cargo across multiple transport modes in one journey while the goods remain in the same container, swap body, or trailer. Transfers happen at rail ramps and marine terminals using lifting equipment. Typical legs include origin drayage, linehaul by rail or vessel, and destination drayage under a through or linked bill of lading. Tracking relies on equipment identifiers such as container, trailer, and chassis numbers across carriers.
- IntralogisticsManagement of material and information flows within a facility or campus from inbound receiving to staging, storage, picking, packing, value added services, and outbound shipping. It covers layout design, equipment and labor planning, and control systems such as WMS, WES, conveyors, sorters, and autonomous mobile robots. Movement and traceability are coordinated between docks, storage locations, workstations, and production lines and tracked with metrics such as throughput, order cycle time, and inventory accuracy.
- Inventory Accuracy RateThe percentage of inventory records that match a verified physical count. Calculated as counted quantity divided by recorded quantity, or as one minus the number of discrepancies divided by the number of records checked. Reported by item, location, or facility and by attribute such as quantity, location, lot or serial number, and condition. Derived from cycle counts or full physical inventories over a defined period.
- Inventory AgingAnalysis of how long inventory has been on hand, measured by days since receipt or last movement and summarized in time buckets such as 0 to 30 days, 31 to 60, and older. It identifies aging stock including slow moving and obsolete items, supports valuation and write down decisions, and informs storage, replenishment, and disposition actions. Common outputs include aging reports by SKU, location, and value, the share of inventory beyond a target age, and average days on hand.
- Inventory AuditA structured examination that compares physical stock with inventory records to verify quantity, location, condition, valuation, and ownership. Procedures include test counts, tracing transactions to and from source documents such as purchase orders, receipts, transfers, and shipments, cutoff checks at period end, and reconciliation of variances. Findings update records and support financial reporting and compliance. Audits may be conducted by internal teams or independent auditors and may be cycle based or full counts.
- Inventory Cycle TimeThe elapsed time between receiving goods into stock and their removal through sale, shipment, or consumption. Often stated in days as days in period divided by inventory turnover. It may also be estimated as average inventory on hand divided by average daily demand. The metric shows how long items remain in storage and informs replenishment and capacity planning.
- Inventory ForecastingThe practice of estimating future stock needs over a defined horizon using data on past demand, on hand quantities, lead times, and open orders. Methods include moving averages, exponential smoothing, and time series models. Results guide reorder points, safety stock levels, and purchase or production schedules. Accuracy is often tracked with measures such as mean absolute percentage error and forecast bias.
- Inventory ManagementThe planning, tracking, and control of stock from purchase through storage, replenishment, picking, and disposition. It applies methods such as ABC analysis, reorder points, safety stock, economic order quantity, cycle counting, and lot or serial tracking. Decisions draw on demand forecasts, lead times, and on hand balances, typically recorded in WMS or ERP systems with barcodes or RFID. Performance is measured with inventory turnover, days of inventory on hand, carrying cost, and fill rate.
- Inventory TurnoverA metric showing how many times inventory is sold or used and replenished during a reporting period. Calculated as cost of goods sold divided by average inventory valued at cost, with average inventory commonly taken as beginning plus ending inventory divided by two. Some organizations use a retail version based on net sales. Days of inventory on hand equals 365 divided by inventory turnover.
j
- Jewelry FulfillmentWarehousing and order processing for jewelry and watches, from inbound receiving to final delivery. Workflows include controlled storage, SKU and often serial tracking, condition checks, pick and pack using protective and tamper evident packaging, inclusion of documentation such as certificates when supplied, shipment booking with insurance and signature service levels, and returns handling with inspection and reconciliation.
- Just in Time Inventory JITAn inventory method in which materials, components, and finished goods are purchased, produced, or moved only when required for the next step or for customer shipment, keeping on hand stock low. It uses demand signals, frequent replenishment, and coordinated supplier scheduling to time deliveries and production with actual consumption.
k
- Kanban SystemA visual pull method for managing inventory and workflow. Consumption triggers a signal card or digital entry that authorizes replenishment or the next task. It defines reorder points and lot sizes, limits work in process, and synchronizes stages so materials move in response to actual demand.
- Key Performance Indicator KPIA quantifiable metric tied to a defined objective and used to track results over time. In logistics and warehousing, examples include order accuracy rate, on time delivery, inventory turnover, dock to stock time, and cost per order. A KPI states the measure, formula, unit, target, time frame, and data source to enable consistent comparison.
- KittingThe process of assembling separate items into a ready to ship set that is handled as one inventory unit. A kit follows a defined bill of materials, is built under a work order, and includes steps to pick, verify, and package components with any required labels or inserts. Inventory systems deduct component quantities and create a finished kit SKU when the build is completed. Common uses include product bundles, subscription boxes, promotional sets, and pre assembly for manufacturing.
l
- Labor ManagementThe planning, assignment, and measurement of warehouse and fulfillment workforce activity. It covers forecasting staffing needs from order and receipt volumes, building schedules, allocating labor to tasks, and tracking time, attendance, and performance. Labor standards from time studies or historical data define expected rates for picking, packing, putaway, and other tasks. A labor management system links with the warehouse management system to capture scan events and report metrics such as units per hour, utilization, and indirect time. Results provide data for payroll, training, safety procedures, and compliance with labor rules.
- Landed CostThe total expense to move a product from the seller to the buyer’s named location, calculated as purchase price plus freight, insurance, duties and taxes, customs brokerage and clearance fees, port and terminal charges, documentation and security fees, and final inland transport and handling. Components included depend on the Incoterm and the specific point named in the contract.
- Lane AnalysisThe evaluation of freight movement between a defined origin and destination pair using historical shipment data to assess cost and service. Typical measures include volume and frequency, weight and cube, rate per mile or per hundredweight, accessorial charges, transit time, on time performance, claims history, carrier and mode mix, capacity utilization, and variability. Findings inform routing guides, carrier bids, and network design decisions.
- Last In First Out (LIFO)An inventory rotation and cost flow method in which the newest units are issued or recorded first. In accounting it assigns recent purchase costs to cost of goods sold and older costs to ending inventory. In warehouse practice it directs picking from the most recently received stock and contrasts with FIFO.
- Last Mile DeliveryThe final movement of a shipment from a local node such as a distribution center, post office, store, or locker to the consignee. It covers parcels and bulky goods using parcel networks, postal services, couriers, and regional delivery firms. Core tasks include address validation, route planning, pickup from a local terminal or store, delivery attempts, signature or photo proof of delivery, returns pickup, and exception handling. Common service levels are same day, next day, scheduled window, contactless drop off, and white glove. Performance is tracked with on time rate, first attempt success, and cost per stop.
- Lcl Less Than Container LoadAn ocean freight service where shipments from multiple shippers share one container. A consolidator groups cargo at an origin container freight station, issues a house bill of lading to each shipper, and tenders a master bill to the carrier. The container moves to a destination station for devanning, then freight is released for pickup or final delivery. Charges are based on chargeable volume or weight plus common station and documentation fees. Transit typically includes extra time for consolidation and deconsolidation compared with full container load.
- Lead Logistics Provider (LLP)A service model in which one provider designs, coordinates, and oversees a shipper’s entire logistics network. The LLP selects and manages third party logistics providers and carriers, runs transportation procurement, sets routing and service standards, and allocates loads. It operates centralized planning and visibility, often through a transportation management system, and reports performance against agreed metrics. Distinct from a 3PL that executes specific services, the LLP serves as the single coordination point across all logistics partners.
- Lead TimeThe total elapsed time between starting an activity and its completion. In supply chain contexts it is the interval from placing a purchase order to having goods available for use or sale, covering order processing, production or picking and packing, transportation, customs clearance when applicable, and receiving. Common types include supplier lead time, manufacturing lead time, customer order lead time, and cumulative lead time. It is measured in days or hours and informs reorder points, safety stock, and delivery commitments.
- Lean WarehousingThe application of lean principles to warehouse operations to reduce waste, standardize work, and accelerate material flow. It focuses on waste types such as waiting, excess transport, unnecessary motion, overproduction, defects, excess inventory, extra processing, and underused skills. Common practices include 5S, visual management, standard work, value stream mapping, pull based replenishment, slotting reviews, smaller batch sizes, cross docking, and continuous improvement through kaizen, tracked with metrics such as dock to stock time, order cycle time, pick accuracy, labor productivity, and space utilization.
- Lease A lease is a legally binding agreement that grants a tenant the right to use or occupy a property, equipment, vehicle, or other asset in exchange for regular payments to the owner (lessor) for a specified period. Leases define important terms such as payment amounts, responsibilities, usage restrictions, and renewal options. Lease terms can vary widely depending on the agreement, ranging from short-term arrangements lasting a few months to long-term contracts that extend for several years.
