Cargo rarely sits at a port because of the cargo. It sits because one document says 24,000 kg and another says 24,000.5 kg, or because a certificate was issued in the name of a sister company.
The core set
Five documents travel with almost every shipment. The commercial invoice states what was sold and for how much. The packing list states how it is packed, in what count and at what weight. The bill of lading is the carrier's receipt and, in its negotiable form, the title to the goods. The certificate of origin states where the goods were produced. The phytosanitary certificate confirms the consignment was inspected and found free of quarantine pests.
Everything else is destination specific or contract specific.
The most common cause of delay is not a missing document. It is two documents that disagree with each other.
Consistency is the whole game
Product description, HS code, net weight, gross weight, number of packages, marks, vessel, container and seal number should match across every paper in the set. Copy the description from the contract into all of them rather than retyping it, and check the weights once at the end.
We send draft documents before finalising for exactly this reason. It takes you ten minutes and saves a week.
The ones that hold things up
Certificate of origin and phytosanitary are issued by external authorities, so they run on someone else's calendar. Preferential certificates of origin, where a trade agreement gives your import a duty benefit, take longer and have to be applied for correctly the first time.
Certificates of analysis from an external laboratory are the other common bottleneck. Residue panels can take a week or more. If your contract requires one, the sample has to go to the lab well before the vessel, not after.
Destination specific paperwork
Health certificates, fumigation certificates, non GMO or non irradiation declarations, halal or kosher certificates, and country specific import permits all appear depending on where the box is going. There is no universal list, which is why we ask for your customs broker's requirement sheet at contract stage.
Original versus scan
Scans go out as soon as the set is ready. Originals travel by courier and can take several days. Where your bank or customs needs originals in hand before release, factor that into your planning, or ask about a telex release arrangement with the carrier.
A short checklist
- Does the exporter name match on every certificate and on the invoice?
- Do net and gross weights agree across invoice, packing list and bill of lading?
- Is the HS code the same everywhere, and is it the code your broker expects?
- Are container and seal numbers correct on all documents?
- Has anything with an expiry date expired?
This is general trade practice, not customs advice. Your broker and your local rules decide what is required.
