What is a bill of lading and why it controls your China shipment

The three functions of a bill of lading

A bill of lading does three things simultaneously, and each matters for the importer:

• Contract of carriage: the B/L records the agreed terms between the shipper (your supplier or freight forwarder) and the carrier (the shipping line). It specifies the origin port, destination port, vessel name, voyage number, and the terms under which the carrier will transport and deliver the goods.
• Receipt of cargo: by issuing the B/L, the carrier acknowledges it has received the goods in the condition described. If the B/L says 'clean on board,' the carrier received the goods without visible damage. A 'claused' or 'dirty' B/L indicates the carrier noted damage or discrepancy at loading.
• Document of title (for negotiable B/Ls): in negotiable form, the original bill of lading represents title to the goods. The carrier will only release the cargo to whoever presents the original. This is why original B/Ls are sent by courier and why losing one is a serious problem.

Negotiable vs. non-negotiable bills of lading

There are two main types, and which one you use affects how the cargo is released:

• Negotiable (original) B/L: also called an 'order B/L.' Three originals are typically issued. The carrier releases the cargo only when the importer presents one original at destination. The original can be transferred to a third party by endorsement, making it a tradeable instrument. Used in letter of credit transactions and when the supplier needs title assurance before payment.
• Non-negotiable (straight) B/L / seaway bill: the cargo is released to the named consignee without presentation of an original document. The consignee only needs to identify themselves. Faster and simpler -- no waiting for couriered originals -- but provides no title security. Used in trusted relationships where payment is settled separately.

For most T/T payment transactions between established parties, a seaway bill (non-negotiable) is common. For letter of credit transactions, the negotiable original B/L is required by the bank.

Master B/L vs. house B/L

When you ship through a freight forwarder rather than directly with a shipping line, you will see two layers of B/Ls:

• Master B/L (MBL): issued by the shipping line to the freight forwarder. It covers the full container and names the forwarder as the shipper. You typically do not see this document directly.
• House B/L (HBL): issued by the freight forwarder to you (the importer). This is your document -- it names your supplier as the shipper and you as the consignee. The HBL is what your customs broker uses to file the import entry.

For LCL shipments, you will always receive a house B/L. For FCL shipments booked directly with a carrier, you may receive a master B/L. Either way, your customs broker needs the B/L number and a copy to prepare the import entry.

Key fields on a bill of lading

Review these fields carefully when your forwarder sends the draft B/L -- errors here cause delays at destination:

• Shipper: your supplier's name and address. Must match the commercial invoice.
• Consignee: your name and address as the importer of record. For negotiable B/Ls, this may say 'to order' or 'to order of [bank]' in LC transactions.
• Notify party: the party the carrier notifies when the vessel arrives -- usually you or your customs broker.
• Port of loading: the Chinese port where the goods were loaded (e.g. Shanghai, Shenzhen, Ningbo).
• Port of discharge: the US destination port (e.g. Los Angeles, Long Beach, New York).
• Description of goods: should match the commercial invoice. Vague descriptions can trigger CBP queries.
• Number of containers or packages, gross weight, and measurement: used by the carrier and customs. Must match the packing list.
• Freight terms: prepaid (supplier pays ocean freight) or collect (you pay at destination).
• B/L number: your customs broker uses this to track the shipment and file the entry.

Common bill of lading mistakes

These errors are common and cause real delays:

• Wrong consignee name or address: CBP uses the consignee details to identify the importer of record. If your name is misspelled or your address is wrong, corrections require an amendment and take time.
• Releasing cargo without the original B/L: for negotiable B/Ls, the carrier must hold the goods until the original is surrendered. Some importers ask suppliers to surrender the B/L at origin (called 'telex release'), which allows release without courier -- but this must be confirmed in writing with the carrier before departure.
• Mismatch between B/L description and invoice: if the B/L says 'general merchandise' but the invoice lists specific products, CBP may query the discrepancy.
• Wrong port of discharge: if the goods are destined for Long Beach but the B/L says Los Angeles, the goods may arrive at the wrong terminal. Always confirm with your forwarder.

Always review the draft B/L your forwarder sends before it is finalized. Corrections after the vessel sails are possible but slower and sometimes require carrier fees.
