What Is Freight? A Comprehensive Guide

Freight is the commercial cargo — goods, commodities, or raw materials — that moves through the global supply chain by truck, train, ship, or plane. The word also refers to the fee paid to move that cargo. This guide covers the definitions, the four main transport modes, multimodal logistics, Incoterms, freight classes, and how a modern TMS (Transportation Management System) automates it all.

1. Freight vs. shipping vs. cargo

The three terms overlap but are not identical:

• Shipping is the umbrella term — any movement of goods, including a parcel from your local post office.
• Cargo is the physical goods themselves, in transit.
• Freight is commercial cargo (usually > 150 lb / 68 kg per shipment) and the money charged for moving it — as in "the freight was $2,400".

2. The four modes of freight transport

Road freight (trucking)

The workhorse of domestic logistics. Two flavors dominate: FTL (Full Truckload — you rent the whole trailer) and LTL (Less-than- Truckload — your pallets share space with other shippers'). LTL is priced by freight class (NMFC codes 50–500) based on density, stowability, handling, and liability.

Ocean freight

Cheapest per ton-kilometer, slowest, and the backbone of international trade. Priced in FCL (Full Container Load — 20' or 40' container) or LCL (Less-than-Container Load — consolidated). Transit times run 15–45 days depending on lane.

Rail freight

Ideal for heavy, non-urgent cargo over long distances — bulk commodities, autos, intermodal containers. Lower CO₂ per ton-km than trucking; often used as the middle leg of a multimodal move.

Air freight

Fastest and most expensive. Used for high-value, low-weight, or time-critical goods — pharmaceuticals, electronics, spare parts, perishables. Priced by chargeable weight (the greater of actual or volumetric weight).

3. Multimodal and intermodal freight

Modern supply chains rarely use a single mode. Two patterns dominate:

• Intermodal — the same container moves across truck, rail, and ship without unloading the goods. Each leg has its own contract.
• Multimodal — same physical setup, but one carrier issues a single bill of lading and takes responsibility for the whole journey. Less paperwork for the shipper; higher accountability for the operator.

4. Incoterms — who pays and who's liable

Incoterms 2020 (published by the ICC) are the eleven standardized three-letter codes that define where risk and cost transfer between buyer and seller. The five most common in freight:

• EXW (Ex Works) — buyer takes over at the seller's door.
• FOB (Free On Board) — seller delivers to the vessel; risk transfers there.
• CIF (Cost, Insurance, Freight) — seller pays freight + insurance to destination port.
• DAP (Delivered At Place) — seller delivers to the buyer's named place, unloaded.
• DDP (Delivered Duty Paid) — seller covers everything, including import duties.

5. Freight documents you'll actually see

• Bill of Lading (BOL) — receipt, contract, and title document in one.
• Commercial invoice — customs uses it to assess duties.
• Packing list — line-by-line contents per carton/pallet.
• Certificate of origin — proves where the goods were manufactured.
• Air Waybill (AWB) — non-negotiable BOL for air cargo.

6. How freight is priced

Freight rates blend several inputs: distance, mode, weight/volume (whichever is higher — the chargeable weight), freight class or container type, fuel surcharge (BAF), and accessorials (liftgate, inside delivery, detention). Spot rates fluctuate with capacity; contract rates lock in a lane for 3–12 months.

7. The role of a TMS in modern freight management

A Transportation Management System is the software layer that replaces spreadsheets, email threads, and phone calls with a single operational record. A production-grade TMS does five things:

1. Rate & book — compares carrier tariffs, chooses the cheapest compliant option, generates the BOL.
2. Track — pulls GPS/EDI/API updates from carriers and pushes ETAs to the customer without human copy-paste.
3. Audit invoices — matches the invoice to the quote and flags overcharges (typically 3–8 % of freight spend leaks here).
4. Report ESG / carbon — computes CO₂ per shipment using ISO 14083, ready for CSRD.
5. Analyze — cost per lane, on-time %, carrier scorecards, exception root causes.

8. Common freight problems a TMS solves

• "Where is my shipment?" answered by dashboard, not by 20 emails.
• Duplicate invoices and phantom accessorials caught automatically.
• Manual carbon spreadsheets replaced by audit-ready ISO 14083 reports.
• Rate shopping in seconds instead of a 30-minute phone tour.
• Exception alerts (delay, damage, customs hold) before the customer complains.
