The documents
UK customs needs

The five mandatory items

The table below is the checklist we work through with clients on the China–UK lane. The "if it's missing" column is the one worth reading — it separates what genuinely stops a declaration from what merely causes a delay while documents are chased.

An EORI number is not a VAT number

This is the question we field most often, and the one that most often catches out first-time importers. The two serve entirely different purposes:

• EORI number — how customs identifies traders, used on the declaration. UK guidance is explicit: importing goods into England, Wales or Scotland requires an EORI number that starts with GB. Without it no declaration can be filed, even once the goods have landed. Registration guidance is on the official HMRC EORI page.
• VAT number — a tax registration, used to account for and reclaim VAT. It is not a hard prerequisite for clearance, but you need your own UK VAT registration to use postponed accounting or to recover import VAT you have paid.

They are registered separately, serve different purposes and cannot substitute for one another. The classic misunderstanding we see: a seller registers for VAT, assumes that covers clearance, and discovers on arrival that there is no EORI — leaving a scramble to register or to import under someone else's entity, with several days lost.

Who imports decides who reclaims

This section matters more than the checklist, because it determines where responsibility — and recovery — sits. Every UK clearance needs a defined importer of record, and whoever is named on the declaration carries the responsibility. Two models are common on this lane:

• Your own company as importer of record — you need your own GB EORI and usually a UK VAT registration. The advantage is that import VAT is recoverable under the normal rules and the duty and tax record sits in your name; the cost is that accuracy of the declaration is your responsibility, as is answering any subsequent enquiry.
• The forwarder or its nominated entity as importer (typical of DDP) — you do not need your own EORI, but you must still supply accurate descriptions, values and invoice details. The point most often missed: import VAT is normally only recoverable by whoever is named as importer on the declaration. If that is the forwarder's entity, the VAT is not recoverable by you — which changes the true landed cost regardless of what the quote says.

"DDP does not mean there is nothing to manage. It transfers the operation, not your obligation to provide accurate information — and it does not automatically leave the VAT recovery with you."

The two models differ substantially on duty and VAT recovery and on where liability falls if HMRC enquires, so confirm in writing whose name the declaration will be filed in at quotation stage. What a DDP quote does and does not include is set out in our cost breakdown guide.

The invoice is where most rejections happen

If you take only one thing from this guide, take this: the most common reason a UK clearance is rejected is not a missing document — it is a description on the invoice that is too vague to classify.

Words like gift, sample, parts, goods, accessories give the broker nothing to classify against and give customs no basis to judge whether a licence or control applies. The declaration comes back for clarification, which costs two or three days and raises the likelihood of examination.

How to write the description

• Do write: material + purpose + model. For example stainless steel kitchen sink, model XS-200
• Do not write: kitchen products, hardware, samples
• Where one invoice covers several products, list them line by line with a commodity code each — never merge them into a single total

The other fields that go wrong

• Declared value — must match the actual transaction price and your payment records. Understating it to reduce duty falls apart the moment proof of payment is requested, and the consequences outweigh the tax saved.
• Incoterms — state whether the sale is FOB, CIF, DDP or otherwise, because it determines whether freight and insurance are already inside the value and therefore how the customs value is built up.
• Country of origin — the country of manufacture, not the port of loading. This matters most when claiming a preferential rate.
• Party details — the consignee name and address must match the bill of lading consignee and the declared importer. Three names that do not agree will trigger a check.

Classification is the importer's responsibility

UK import declarations use a 10-digit commodity code. One thing to be clear about: a forwarder or broker can suggest a code from the description you supply, but classification is the importer's responsibility and final determination rests with UK customs. Getting it wrong can mean underpaid duty, penalties, or goods held.

Codes can be checked line by line in the official tariff at Trade Tariff: look up commodity codes, duty and VAT rates, which also shows the applicable duty rate and VAT treatment. Where the value is significant or the classification is genuinely arguable, apply to HMRC for an advance ruling — do not rely on a forwarder's verbal confirmation.

Import VAT: pay now or postpone

Import VAT is charged at the standard 20% rate, and the value it is charged on is not the goods value but customs value + duty + transport and incidental costs to the first destination in the UK. HMRC's own statement of that basis is published here, and the arithmetic is worked through in our cost breakdown guide.

There are two ways to handle it, and the cash flow difference is significant:

• Pay at the border — simplest, but the cash goes out first and comes back later through your VAT return.
• Postponed VAT Accounting — eligible UK importers account for import VAT on their VAT return instead of paying at the border. It requires the declaration to be completed correctly with a valid VAT number, and it is not something that can be applied retrospectively.

If you intend to use it, tell your broker before booking and confirm the declaration is completed accordingly. We have had clients who held a VAT number and intended to postpone, but because it was not flagged at declaration stage the VAT was paid in cash and their working capital was tied up unnecessarily.

What certain cargo adds to the list

• Anything on solid wood pallets, crates or dunnage — must be heat treated or fumigated to the ISPM 15 standard and carry the corresponding mark on the timber. This is mandatory, and skipping it can mean treatment at the port, re-export or destruction. Plywood, fibreboard and plastic pallets are not subject to it — a useful way to remove this step entirely on time-critical shipments.
• Batteries, liquids, powders, magnetic goods — an MSDS, a dangerous goods declaration or a non-hazardous assessment may be required depending on mode and battery type. Air acceptance conditions are considerably stricter than ocean, so declare the characteristics at booking rather than at the warehouse.
• Food, food-contact materials, cosmetics — additional compliance and labelling requirements apply and pre-notification may be needed. Take advice from a UK compliance specialist before shipping.
• Products requiring UKCA or CE marking — not a customs document but a product compliance requirement. It is checked on examination, and missing or incorrect marking prevents the goods being placed on the market.

Most hold-ups come down to three things

1. Documents started only after the vessel berths

Our operating rule is the complete clearance pack to the UK broker within 24 hours of sailing. Technically anything arriving before berthing is in time, but sending early gives the broker room to check descriptions, codes and values and to fix problems before the goods land. Start after berthing and the back-and-forth alone costs two or three days, which often eats into free time — after which demurrage and detention accrue daily, as set out in our transit time guide.

2. Three names that do not agree

The consignee on the invoice, the consignee on the bill of lading and the declared importer must be the same entity. What we see in practice: an order placed through a Hong Kong company, goods received by a UK company, and the declaration filed under a third entity. Any mismatch triggers a check. Amendments are possible but cost time, and changing the bill of lading consignee after berthing usually needs the carrier's agreement.

3. Understating the value, then being asked to prove it

Reducing the declared value to save duty is the approach most likely to rebound. Customs can require evidence of the transaction — contracts, payment records, platform statements. Once those do not reconcile, the outcome is back-duty plus penalties, and in serious cases it affects how future consignments are treated. Declaring the actual transaction value is the only sustainable approach. Where duty genuinely needs reducing, the legitimate routes are preferential rates under a certificate of origin and correct classification.

Working backwards from the sailing

• Before ordering — settle who the importer of record will be and register the GB EORI (and UK VAT if required). This step takes the longest and is the worst one to leave late.
• Before booking — fix the commodity code, the cargo characteristics (batteries? solid wood packing?) and the Incoterms. Declaring characteristics up front is what stops a shipment being refused at the origin warehouse.
• At loading — complete wood treatment and marking; check shipping marks against the packing list.
• Within 24 hours of sailing — invoice, packing list, bill of lading, EORI and codes, sent to the UK broker in one go.
• Before arrival — confirm whether VAT will be postponed, that the broker is ready to declare, and that the delivery address and any booking slot are in place.

What this guide does not cover

This guide reflects the day-to-day operational experience of the HSIEHSHUN China–UK desk and is not customs, tax or legal advice. Four points specifically: commodity code classification and the applicable rate are subject to final determination by UK customs; the declaration, postponement and recovery of import VAT depend on the importer's own tax position and should be discussed with your UK accountant or tax adviser; controlled categories such as food, cosmetics and medical devices carry separate compliance requirements not covered here; and UK import rules change, so treat the current version of the official gov.uk guidance as authoritative. The requirements for any individual shipment are governed by your UK broker's written confirmation.
