Logistics is far more than just “trucks and boxes” or moving goods from Point A to Point B. In today’s globalized world, logistics is a strategic function involving technology, regulations, supply chain coordination and precision planning. And like every industry, logistics comes with its own complex vocabulary. From HS Codes and Incoterms to customs clearance and last mile delivery, logistics terminology can be overwhelming especially for non-experts. This brief practical glossary breaks down the most essential logistics terms and definitions, helping you understand how global trade works and empowering better communication with freight forwarders, customs brokers and shipping partners.
The Language of Logistics: Why Terminology Matters
In logistics, every word means something specific. A misunderstood acronym or a misused term can lead to delays, compliance issues or even financial loss. More importantly, clear communication keeps operations running smoothly across multiple players such as shippers, carriers, customs officials and clients. That’s why getting comfortable with logistics terms is more than academic, it’s a real-world necessity. Let’s start with the basics and build our way up:
Supply Chain – consists of the series of activities and organisations that materials move through on their journey from initial suppliers to final customers.
Freight – refers to goods or commodities that are transported in bulk by various modes of transportation — air, sea, road or rail — from one location to another for commercial purposes.
Reverse Logistics – is the process of moving goods backward in the supply chain for returns, recycling or disposal. It plays a key role in sustainability and after-sales services.
Air Freight & Shipping
Main Deck - the primary cargo-carrying floor of an aircraft. It holds the largest and often heaviest shipments, especially in freighter aircraft or converted passenger planes.
Lower Deck - the space beneath the main deck, often used in passenger aircraft to carry cargo alongside luggage. It’s essential for maximizing capacity on commercial flights.
Wide-Body Aircraft – large aircraft with two aisles and high cargo capacity; used for long-haul and heavy shipments.
Narrow-Body Aircraft – smaller aircraft with one aisle; used for short- to medium-haul routes and regional cargo.
Leg (Flight Leg) – a single segment of a multi-stop air freight route (e.g., Tashkent–Istanbul is one leg).
ULD (Unit Load Device) – standardized air freight pallets or containers used to load cargo efficiently and safely.
Chargeable Weight – the greater of actual weight or volumetric weight, used to calculate air freight cost.
Transit Time – total time taken from cargo departure to arrival at final destination.
FCL (Full Container Load) – when you book an entire container for your cargo, even if you don’t fill it all. You pay for privacy, speed and control.
LCL (Less than Container Load) – you share container space with other shipments. Cost-efficient but slower and riskier.
Air Waybill (AWB) – the document accompanying air shipments, acting as a receipt and contract of carriage.
Bill of Lading (B/L) – the single most important transportation document that is the basic operating document in the industry.
Warehousing & Inventory
WMS (Warehouse Management System) – is a software package that provides oversight of the storage and flow of materials within a company’s operations.
Inventory Turnover Ratio – measures how many times a company sells and replaces its stock over a period. A higher turnover indicates efficient inventory management, while a lower one signals overstocking or weak sales.
Cross-Docking – goods move from inbound to outbound trucks with minimal or no storage. Speed wins here.
Customs, Trade & Compliance
HS Code (Harmonized System Code) – codes used by customs authorities worldwide to identify and levy duties on products crossing international borders.
Incoterms – are international terms of trade that govern the responsibilities of the parties to a contract when importing and exporting goods.
Customs Value – is the total value of imported goods as determined by the customs authority of the importing country. It serves as the basis for calculating import duties, taxes (such as VAT) and other customs-related charges.
Logistics Strategy: Beyond Day-to-Day Operations
Freight Forwarder – a logistics intermediary that arranges the international movement of goods on behalf of shippers. Freight forwarders coordinate carriers, documentation, customs clearance and shipment tracking, ensuring smooth and efficient delivery.
3PL (Third-Party Logistics Provider) – a company that handles logistics operations for other businesses. They don’t own your product but they manage the movement, storage and sometimes returns.
Lead Time – the time between placing an order and receiving it. The shorter, usually the better.
Last Mile Delivery – the final step in the delivery chain, often the most complex. Think of delivering packages to homes in rural areas or congested city centers.
Cost & Performance Terminology
Landed Cost – the total cost of getting a product to its destination, including purchase price, shipping, customs duties and handling fees.
Demurrage – penalty charges for using containers or trucks beyond the agreed free time.
KPI (Key Performance Indicator) – logistics loves data. From on-time delivery rate to cost-per-shipment, you can track it all.
Digital & Modern Logistics
TMS (Transport Management System) – software that optimizes routes, tracks shipments and handles transport documentation.
Digital Freight Forwarders – online platforms offering instant quotes, real-time tracking and automated documents.
Blockchain in Logistics – refers to the use of distributed ledger technology (DLT) to record, verify and share supply chain and shipping data across all parties involved in the movement of goods
