Understanding China export documents

Your goods can be perfect and your supplier honest, and your shipment can still sit stuck at the port because a document is wrong. A large share of shipment delays trace back to paperwork that is incomplete or inconsistent, not to anything physically wrong with the cargo. For a Nigerian importer, understanding the handful of documents that travel with your goods is not bureaucracy, it is the difference between clean clearance and an expensive wait.

This is general information, not legal advice. Your clearing agent and a professional should guide anything unusual.

The four documents you will see most

Every shipment from China carries a small core of documents. Four of them matter most to you:

• Commercial invoice. The record of the transaction: who is selling, who is buying, what the goods are, the quantity, the unit and total value, the currency and the trade terms. Customs leans on this to assess value and duty.
• Packing list. What is physically in the shipment: how the goods are packed, the number of cartons, weights and dimensions. It lets customs and your forwarder check the cargo against the paperwork.
• Certificate of origin. A statement of where the goods were actually made. It can affect the duty treatment your shipment receives and is often asked for at the Nigerian end.
• Bill of lading, or the air waybill for air freight. The carrier's document acknowledging the goods and acting as the contract of carriage and, for sea freight, a document of title that controls who can collect the cargo.

Why each one matters to you

The commercial invoice drives your duty, so an inflated or vague value costs you, while an unrealistically low one invites questions. The packing list is what your forwarder and customs use to confirm nothing is missing or mislabelled. The certificate of origin can change the rate you pay. The bill of lading is the one that decides whether you, and not someone else, can actually take delivery, which is why you never treat the original casually.

Customs does not see your goods first, it sees your documents first. If the documents do not add up, the goods wait.

Consistency is the quiet rule

The single most common avoidable problem is documents that disagree with each other. The product description, quantity, value and weights should match across the invoice, the packing list and the bill of lading. A mismatch, even an innocent typo, is exactly what slows a file down or triggers a query. Before anything ships, line the documents up side by side and check that they tell one consistent story.

This also has to line up with your own filing on the Nigerian side. The product description should map sensibly to your declared classification, which is why it pays to understand HS codes and Nigerian customs duty before the goods leave China.

Get the details right at the source

Because the supplier usually prepares these documents, you have the most influence before the order ships. Make it a clause, as in quality clauses every purchase agreement needs, that the supplier provides accurate documents matching the agreed specification and your real details. Ask to see drafts of the invoice and packing list before shipment so you can catch errors while they are still easy to fix.

A pre-shipment document checklist

• Commercial invoice with correct buyer, seller, values, currency and trade terms.
• Packing list matching the invoice on quantities, cartons and weights.
• Certificate of origin where your clearance needs one.
• Bill of lading or air waybill with consistent descriptions and consignee details.
• Any product-specific certificates your goods require.
• Every description consistent across all documents and your own filing.

Get the documents right and the rest of the clearance gets much easier. For the close detail on two of these, read invoices and packing lists, done right. When the goods and the paperwork are both in order, you can make a request to settle your supplier on Alipay from Naira and keep that receipt with the shipping file.
