Bill of Lading (B/L or BoL)

A bill of lading (B/L) is the foundational document in international sea freight. It does three things at once: it proves the carrier received your goods in apparent good order, it sets out the contract of carriage (who, what, from where, to where, under what freight terms), and — if it's a negotiable original — it's a document of title. Whoever holds and endorses the original B/L controls the cargo.

Negotiable vs straight (non-negotiable). A "to order" bill of lading (negotiable) can be endorsed over to a new party — banks use this in letters of credit. A "straight" bill names the consignee outright and is non-transferable. Most e-commerce and SME imports use straight bills or surrendered originals (see below).

Original surrender vs telex release vs sea waybill. Classic B/Ls require the original document to collect cargo — a problem when the goods arrive before the papers. "Surrendering" the originals at origin and sending a telex release message to destination avoids this delay. A sea waybill is a non-negotiable alternative that never requires original surrender; the named consignee can collect with ID only.

Master vs house bill. An NVOCC issues a "house bill of lading" (HBL) to the actual shipper, while the ocean carrier issues a "master bill of lading" (MBL) to the NVOCC. The shipper sees the HBL; the MBL is between carrier and forwarder. Both reference the same cargo but name different parties.

Air freight equivalent. An Air Waybill (AWB) is the equivalent document for air cargo. It is always non-negotiable (straight) — airlines do not issue title documents — so the consignee can collect on ID only.
