What documents are needed for UK customs clearance

The short answer, then the detail

For a straightforward commercial shipment from China you need a commercial invoice, a packing list, the transport document (a bill of lading for sea freight or an air waybill for air), and the import declaration itself. Behind those you need an EORI number, the correct commodity code, and any licences or certificates your particular goods require.

Most delays are not caused by a missing document in the abstract. They are caused by a document that exists but disagrees with another one, or by a certificate nobody realised the goods needed. Both are avoidable before the vessel sails, and expensive afterwards, because goods waiting at the port accrue charges daily.

This guide is about the paperwork itself. If you want the clearance process end to end, including registering for an EORI number and how the declaration is made, start with our guide to UK customs clearance, and use this one as the checklist alongside it.

The commercial invoice

This is the document customs works from, and it does more than state a price. It should identify the seller and the buyer, describe the goods in plain terms that match the commodity code, and give quantities, unit prices, the total, the currency and the incoterm with the named place.

It also needs the country of origin. Origin is not the country the goods were shipped from, it is where they were produced, and it drives the duty rate and whether anti-dumping duty applies. Getting this wrong is one of the more serious errors available.

Vague descriptions are the most common problem. Samples, gifts, parts and general merchandise are not descriptions customs can classify from, and an invoice that does not support the commodity code declared is the sort of discrepancy that turns into a query.

The packing list and the transport document

The packing list sets out how the consignment is physically made up: number of cartons, contents of each, net and gross weights, dimensions and markings. It has to agree with the invoice, and the weights have to agree with what the carrier recorded, because a mismatch is a straightforward reason to hold a shipment.

The transport document is a bill of lading for sea freight or an air waybill for air. A bill of lading is also a document of title in its usual form, which means it controls release of the goods; an original bill of lading sitting in a courier bag while your container sits at the port is a classic and expensive delay.

Agree early with your supplier and forwarder which type of bill you are using and how it will be released, because this is a process question that only becomes urgent at the worst moment.

Your own registrations and numbers

You need an EORI number beginning with GB to import into Great Britain. It is free and usually issued quickly, but apply before you need it rather than while a container is arriving, because there is no way to clear goods without one.

You need the commodity code, and the responsibility for it being correct is yours even when a broker keys it in. Get it right before ordering, both because it sets the duty rate and because it tells you whether anti-dumping duty applies.

If you are VAT registered, give your VAT number to whoever makes the declaration and tell them you are using postponed VAT accounting, so import VAT goes on your VAT return instead of being paid at the border. It needs no approval, but it does not happen automatically.

The documents that depend on your goods

This is where shipments actually get stopped, because these are the ones nobody thinks about until a certificate is requested.

If your goods are regulated, you need the compliance evidence in your hands as importer: a declaration of conformity and the technical documentation behind it, plus the test reports and certificates for the category. Food contact goods need a declaration of compliance, and polyamide or melamine kitchenware from China or Hong Kong needs a laboratory report as well, together with prior notification to the authority at the first point of introduction at least two working days before the goods arrive.

Beyond that, controlled goods need licences, lithium batteries and similar items need dangerous goods documentation, and if you are the first to place a listed timber product on the market you need your due diligence records. The one that catches people most often is wooden packaging: pallets and crates have their own treatment requirements, which is a rule about what the goods travel on rather than what they are.

Preference documents are the exception worth knowing: there is no UK trade agreement with China, so there is no preferential origin claim to make on Chinese origin goods, whatever a supplier's paperwork suggests.

Keeping the file afterwards

Clearance is not the end of the paperwork. You must keep the documents supporting your customs value for at least four years, and compliance documentation for the periods each regime requires, which can be considerably longer.

Keep the quotation, specification, invoice, packing list, transport document, declaration, duty and VAT records and any certificates together as one file per shipment. When a query arrives, the importer who can produce a consistent set of documents has a short conversation, and the one who cannot has an expensive one.
