- 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.
