Trade documentation: the paper that moves the cargo

In physical trading, documents are not paperwork — they are the trade. The cargo may be on a ship in the middle of an ocean, but ownership, payment and customs clearance all move through documents. Control the documents and you control the goods. Get one document wrong and the bank won't pay, the cargo won't clear, and the deal stalls.

The bill of lading — the most important document

The bill of lading (B/L) issued by the carrier does three jobs at once: it is a receipt that the goods were loaded, evidence of the contract of carriage, and — crucially — a document of title. Whoever holds an original negotiable B/L controls the cargo and can claim it at the destination. Originals are usually issued in a set of three; presenting one 'accomplishes' the set.

Negotiable (to order) B/L

Title can be transferred by endorsement — it can be bought, sold and pledged while the cargo is at sea.

Straight B/L

Consigned to a named party only; not transferable.

Sea waybill

A non-negotiable receipt; faster but gives no document-of-title control.

Clean B/L

No notation of damage or shortage at loading — required by most letters of credit.

The supporting document set

• Commercial invoice — the seller's bill: goods, quantity, price, terms.
• Packing list — how the cargo is packed, weights and dimensions.
• Certificate of Origin (COO) — states the country where the goods were produced; needed for customs and tariffs.
• Certificate of Quality / Analysis (assay) — independent confirmation the goods meet the contract specification.
• Weight certificate / draft survey — independent confirmation of quantity loaded.
• Inspection certificate — from an agency such as SGS, Bureau Veritas or Intertek, often at load and/or discharge.
• Phytosanitary certificate — for agricultural/plant cargo, confirming it is pest- and disease-free.
• Insurance certificate / policy — proof of marine cover (required under CIF/CIP).
• Certificate of Insurance, fumigation, health, halal/kosher — depending on commodity and destination.
