Plain-English definitions of the freight, customs, claims and custody terms used across these guides. Legal terms are described for orientation only.
- 3PL (third-party logistics provider)
- A company that performs logistics services such as warehousing, transport and fulfillment on behalf of a shipper, usually for goods it does not own.
- Accessorial charge
- A charge for a service beyond basic transport, such as liftgate delivery, inside delivery, or truck detention.
- AWB (air waybill)
- The transport document for air cargo. It is a receipt and evidence of the contract of carriage, but unlike a negotiable ocean bill of lading it is not a document of title.
- B/L (bill of lading)
- The transport document issued by a carrier when it takes goods: a receipt for the goods, evidence of the contract of carriage and, when negotiable, a document of title that controls who may take delivery. See bill of lading types.
- Carmack Amendment
- The US federal law, now at 49 U.S.C. § 14706 for motor carriers and freight forwarders (with a parallel rail provision at § 11706), that governs carrier liability for loss and damage in interstate shipments. It sets minimum periods of 9 months to file a claim and 2 years to sue. See the freight claim process.
- CFS (container freight station)
- A facility where less-than-container-load cargo is consolidated into, or unpacked from, shared containers.
- Chain of custody
- The unbroken record of who was responsible for goods and when responsibility passed between parties. See the guide and the form template.
- Clean and claused bills of lading
- A clean bill records goods received in apparent good order. A claused (or foul) bill notes damage, shortage or defective packing at loading.
- CMR
- The Convention on the Contract for the International Carriage of Goods by Road, and the consignment note used under it.
- COGSA

- Damage that could not be seen at delivery, usually found when the goods are unpacked. See concealed damage claims.
- Consignee / consignor
- The consignee is the party the goods are delivered to. The consignor (or shipper) is the party that hands them over for carriage.
- CY (container yard) and cut-off
- The terminal area where containers are received and stored. The cut-off is the latest time a container can arrive and still make its scheduled vessel.
- Demurrage
- In container shipping, usually a charge for a container kept in the terminal beyond its free time. Definitions vary by contract. See demurrage and detention invoices.
- Detention
- In container shipping, usually a charge for keeping a container outside the terminal beyond its free time. In trucking, a charge for keeping a driver and truck waiting beyond the agreed time at a stop.
- Drayage
- Short-distance trucking of containers, typically between a port or rail terminal and a nearby warehouse.
- eBL (electronic bill of lading)
- A bill of lading issued and transferred electronically, where control of the electronic record takes the place of possession of paper originals.
- ePOD (electronic proof of delivery)
- A proof of delivery captured on a device, often with a typed name, signature, photos and a time and location stamp.
- ETA / ATA
- Estimated and actual time of arrival. An ETA is a forecast, not a measurement. See shipment visibility.
- Excursion (temperature)
- Time a product spends outside its required temperature range. See temperature excursion records.
- FCL / LCL
- Full container load (one shipper's cargo fills the container) and less than container load (cargo shares a container with others).
- Fictitious pickup
- A theft in which someone posing as the assigned carrier collects a load. See cargo theft prevention.
- Freight forwarder
- A company that arranges transport on a shipper's behalf, booking carriers, preparing documents and often handling customs, frequently without owning the vehicles.
- Free time
- The period a container may stay in the terminal, or out of it, before demurrage or detention charges begin.

- House and master bills of lading. The ocean carrier issues the master bill to whoever booked the space; a forwarder or NVOCC issues house bills to its own customers.
- HS code

- Incoterms
- The International Chamber of Commerce rules (for example FCA, FOB, CIF, DAP, DDP) that define which party arranges and pays for each stage of transport and where risk passes.
- ISO 17712
- The international standard for mechanical freight container seals, which classifies them as indicative (I), security (S) or high security (H).
- Leg
- One movement within a journey, such as a truck from factory to port, or a vessel from port to port. Most shipments have several.
- NVOCC
- Non-vessel-operating common carrier: a company that acts as an ocean carrier to its customers, issuing its own bills of lading, without operating the ships.
- OS&D
