Switch bills of lading: legitimate, useful, and easy to misuse

Switch bills come up whenever a trader buys from one party and sells to another without wanting either to meet.

Why they exist

An intermediary buys goods in China and sells them to a buyer in Europe. The original bill names the Chinese supplier as shipper. If that document reaches the European buyer, they now know the source and can go direct next time.

A switch bill replaces the first set with a new one naming the intermediary as shipper. Same cargo, same vessel, different paperwork. It can also be used to change the discharge port or split one bill into several for onward sale.

The rules that matter

Every original from the first set must be surrendered before the second set is issued. This is not a formality. If both sets exist at once, two different parties can each claim the cargo with a valid looking document, and the carrier is exposed to both.

The cargo description, weights and container numbers must stay the same. Changing them turns a routine commercial arrangement into misdeclaration.

Where it goes wrong

Two situations. An original from the first set is lost or never returned, and the carrier issues anyway against a letter of indemnity. And a switch that changes more than the shipper's name, which crosses from confidentiality into misrepresentation.

If you are the party requesting a switch, get written confirmation that the first set has been surrendered in full. If you are receiving cargo on a switched bill, understand that you cannot see who actually shipped it, which matters for origin claims and for sanctions screening.
