# Bill of Lading (BL): what it is, the types, and telex release

> The document that controls your cargo: what a BL is, original vs. express release, and how your freight actually gets released at destination.

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](https://www.freightspot.com/en/resources/help/carta-porte-quien-la-necesita).

**Got a BL with a bad data point and the cargo already on the water?** [Write to us](https://www.freightspot.com/en/contact): the earlier it’s caught, the cheaper it is to fix. And if any term here reads like a foreign language, [the glossary](https://www.freightspot.com/en/resources/glossary) translates it.
