A bill of lading does three jobs at once, and most confusion about it comes from forgetting that. It is a receipt confirming the carrier took your goods in the stated condition, it is evidence of the contract of carriage, and — when issued as a negotiable original — it is a document of title, meaning whoever holds the endorsed original controls release of the cargo. An air waybill, by contrast, is only a receipt and a contract; it is not negotiable and cargo is released to the named consignee. That single difference explains why an ocean shipment can be held at destination for a document that has not arrived, while an air shipment usually cannot.
The top block names the parties. Shipper is the party handing over the goods, usually the exporter. Consignee is who may claim them. Read this box carefully: if it names a company, only that company can take delivery; if it reads "to order" or "to order of shipper", the document is negotiable and must be endorsed on the reverse before it can be transferred, which is how letters of credit keep control of cargo until payment. Notify party is who the carrier's agent contacts on arrival — often a customs broker — and naming someone there gives them no right to the cargo at all.
The routing block separates four places that are frequently confused. Place of receipt is where the carrier's responsibility begins, which for a door pickup is the factory, not the port. Port of loading and port of discharge are the sea legs. Place of delivery is where carriage ends. If the place of receipt and place of delivery are inland, you are holding a through or combined transport bill covering the whole movement; if they are blank and only the two ports appear, the carrier's liability runs port to port and the inland legs sit with you. Check that this matches the Incoterm on your invoice.
The cargo block carries the data customs and the carrier will both rely on. Marks and numbers identify the packages; the goods description should match the commercial invoice and be consistent with the HS code you have declared; container and seal numbers must match what was actually loaded; and gross weight and measurement drive both charges and stowage. The phrase "said to contain" appears because the carrier counted containers, not cartons — it did not verify what is inside. Also look for the shipped-on-board date and any clause about damaged or defective packaging. A bill without adverse remarks is a clean bill; a claused bill can be rejected under a letter of credit.
The remaining fields decide money and timing. Freight prepaid means charges are settled at origin; freight collect means the consignee pays before release. Number of original bills issued is usually three, and one surrendered original renders the rest void. If you do not need the document of title function — for example you are shipping between related companies, or you are already paid — ask for an express release or sea waybill instead, which removes the risk of cargo waiting at destination for couriered paper. Corrections after issue are possible but generally attract an amendment fee and can delay release, so the cheapest time to check every field is before the bill is issued.
We prepare and check these documents on the shipments we handle, across sea, air and rail. If you want a draft bill reviewed against your invoice, packing list and letter of credit before it is finalised, send us the set and we will come back with what needs correcting.
