The Bill of Lading (BL) is the document the ocean carrier issues when it takes custody of your cargo. It does three jobs at once — and the third one is where most of the trouble comes from:
- It’s the receipt proving the cargo was handed to the carrier.
- It’s the contract of carriage between the parties.
- It’s the document of title: whoever holds the original BL controls the cargo.
That third function is why a badly issued BL can leave your goods sitting at the port, untouchable — even after you’ve paid for them in full.
The types you’ll run into
| Type | How it works | When it’s used |
|---|---|---|
| Original (negotiable) | Three paper originals are issued; one physical copy must be surrendered at destination | When the seller wants payment guaranteed before the cargo is released |
| Telex release | The shipper surrenders at origin and the carrier notifies destination; no paper travels | The most common setup today: payment already made and trust between the parties |
| Express release (seaway bill) | Non-negotiable, released automatically to the consignee | Intercompany moves, or a supplier you fully trust |
| Master vs House | The carrier issues the master to the forwarder; the forwarder issues the house to you | In consolidated cargo both always exist |
The original-BL trap
If your shipment moves on an original BL, someone has to courier a piece of paper from one country to another. If that document runs late — or gets lost — your cargo arrives and you can’t pick it up until the original shows up. Meanwhile: storage charges and demurrage, both on the clock. So unless there’s a real financial reason for it, ask for telex release.
What to check on the draft
The carrier sends you a draft before issuing. It’s your one cheap chance to fix things. Verify:
- Shipper, consignee and notify party — the consignee must be exactly the entity that will clear customs, full legal name.
- Cargo description — it has to match your commercial invoice and your customs entry (pedimento).
- Package count, gross weight and volume — mismatches here turn into discrepancies at clearance.
- Container and seal numbers.
- Port of loading, port of discharge and final destination.
- Freight terms: prepaid (paid at origin) or collect (payable at destination).
Fixing a draft is free. Fixing an issued BL costs an amendment fee and can take days. Fixing it after the vessel has sailed costs more still.
What about air and trucking?
- Air: the equivalent is the Air Waybill (AWB), which is not a document of title — it’s only a receipt and a contract. That’s why air cargo releases so much faster.
- Trucking within Mexico: the Carta Porte (Mexico’s e-waybill), a tax supplement with rules of its own — we break it down here.
