Commercial Invoice and Packing List for UK Imports from China: What to Check Before Shipping
Blog 2026-10-28
A commercial invoice and packing list for UK imports serve different purposes: the invoice describes the transaction and value, while the packing list explains how the goods are physically packed. Before a supplier dispatches goods from China to Great Britain, compare the descriptions, quantities, package details and references against the purchase order and actual cargo. The documents do not need to look identical, but overlapping information should agree or be reconcilable. This guide shows you what to check, who should resolve discrepancies and how to hand over the final documents.

What are a commercial invoice and packing list used for?
The two documents describe the same shipment from different perspectives.
A commercial invoice normally records the seller, buyer, goods, quantities, prices, currency and agreed transaction details. It helps the importer and customs representative understand the transaction. HMRC identifies commercial invoices among the documents an importer may be asked to provide to support customs valuation.
A packing list describes the physical consignment: what has been packed, how many packages there are, their contents and relevant weights and dimensions. It helps the forwarder, warehouse, receiving team and customs representative identify the cargo.
Neither document replaces the purchase contract, transport document or any licence or certificate applicable to the goods. Having both documents does not, by itself, establish that the goods comply with UK product requirements.
| Question | Commercial invoice | Packing list |
|---|---|---|
| Main purpose | Describe the transaction and goods value | Describe the packed shipment |
| Typical information | Seller, buyer, product descriptions, quantities, prices and currency | Product or SKU references, package count, contents, weights and dimensions |
| Common users | Buyer, importer and customs representative | Forwarder, warehouse, receiving team and customs representative |
| Key check | Does it reflect the actual transaction? | Does it reflect the goods actually packed? |
This table shows common uses and examples, not a universal legal template. The format, information and supporting documents needed depend on the goods, transaction and import arrangements. Ask your appointed customs representative and transport provider what they need before the supplier finalises the documents.
Which details should you check before dispatch?
Compare the commercial invoice and packing list for UK imports with the purchase order, final packed goods and available transport instructions. A detail does not have to appear in the same format on every document, but the information must be consistent or capable of being reconciled.
| Check | What to compare | Who should confirm | If there is a discrepancy |
|---|---|---|---|
| Parties and references | Seller, buyer, consignee, order and shipment references | Buyer and supplier; importer or representative where relevant | Confirm each party’s role and correct the relevant record. |
| Product descriptions | Product name, material, use and SKU references | Supplier and buyer | Replace vague wording with an accurate description of the goods. |
| Quantities and units | Units per SKU, total units and unit of measure | Supplier and buyer | Reconcile the order, invoice and packed quantities; explain any agreed partial shipment. |
| Cartons and contents | Package count, marks and which SKU is in each carton | Supplier and warehouse or forwarder | Check the actual cargo and issue a corrected packing list if needed. |
| Weight and dimensions | Net and gross weights and packed measurements | Supplier and forwarder | Confirm the measurement basis and obtain revised figures where necessary. |
| Value and currency | Unit price, total price, currency and supporting transaction records | Buyer and supplier; customs representative as appropriate | Confirm the actual transaction and provide supporting evidence. Do not guess the customs value. |
| Origin of the goods | Country of origin and available supporting evidence | Supplier and importer; customs representative as appropriate | Check the relevant origin information and evidence for the goods. Do not assume that the dispatch country is always the country of origin. |
| Document coverage | Whether each document covers the whole order, a partial shipment or a particular supplier | Buyer, supplier and forwarder | Identify the goods covered by each document and make the records reconcilable. |
| Delivery and transport details | Named destination, booking reference and agreed handover details | Buyer, supplier and forwarder | Align the documents and booking instructions before release or dispatch. |
Net weight and gross weight are different measurements, so a difference between them is not automatically an error. Likewise, an invoice may cover the whole order while a packing list covers one partial dispatch. Make the scope clear so the quantities can be reconciled.
The invoice price is not automatically the final customs value. Depending on the transaction and applicable valuation rules, the customs representative may need to consider additional information or adjustments.
If the supplier has quoted a sales term, confirm the rule, edition and named place. Our guide to incoterms for UK importers explains the separate question of buyer and seller handover.
Illustrative: checking two suppliers’ documents before a UK shipment
A UK homeware retailer is preparing a combined shipment from two suppliers in China to a distribution centre in Birmingham. The buyer has two checks to complete before dispatch:
- One supplier has described its products on the invoice simply as “household goods”.
- The combined packing-list summary shows 29 cartons, although the supplier-level packing records indicate 30 cartons.
The buyer needs to establish what the goods are and which cartons are actually ready to ship. Matching the headline total alone is not enough.
Step 1: Identify what each supplier is sending
| Supplier | Product and SKU | Units | Confirmed packing | Cartons |
|---|---|---|---|---|
| Supplier A | Plastic storage baskets — SKU A | 400 | 20 units per carton | 20 |
| Supplier B | Textile storage organisers — SKU B | 200 | 20 units per carton | 10 |
| Total | Two suppliers, two SKUs | 600 | — | 30 |
Each supplier’s invoice and packing information should still be identifiable against its own goods and transaction.
Step 2: Resolve the two discrepancies
| Issue | What the buyer checks | Agreed next action |
|---|---|---|
| Vague description | The buyer asks Supplier A to confirm the product name, material and intended use against the actual goods. | Supplier A revises the description so the invoice accurately identifies the product. The buyer shares the updated information with the appointed customs representative. |
| Carton count | The buyer asks both suppliers or the relevant receiving warehouse to confirm the cartons actually packed or received, rather than assuming the summary is correct. | Once 20 cartons of SKU A and 10 cartons of SKU B are confirmed, the party responsible for the combined summary corrects the total to 30. |
| Document coverage | The buyer checks which invoice and packing record belongs to each supplier and whether both orders are included in the same dispatch. | The final document set identifies the supplier and goods covered by each record. Any agreed partial shipment is clearly distinguished. |
A clearer description helps the parties understand the goods, but it does not by itself establish the correct commodity code or prove product compliance. The importer and appointed customs representative should confirm the information and evidence needed for the actual declaration.
Step 3: Hand over the final document set
Before dispatch, the buyer records the final document versions and sends them to the relevant parties:
- Suppliers: confirm the goods, quantities, descriptions and packed cartons.
- Buyer and importer: check the transaction information, identify the importing entity and resolve outstanding questions.
- Freight forwarder: receive the final packing and shipment information needed for the agreed booking.
- Appointed customs representative: receive the relevant final transaction and shipment information and confirm any additional declaration requirements.
If a supplier later changes the packed quantity or a document is amended after booking, the buyer should notify the parties using that information. They should then confirm whether the booking, declaration or supporting records need to be updated.
What this example shows: a useful document check connects each supplier’s transaction with the goods actually packed. It helps identify questions before dispatch, but it does not guarantee customs release or delivery by a particular date.

Who prepares and checks the documents?
A commercial invoice and packing list should have clear owners. The exact allocation depends on the contract and service arrangements, but the following handover is a practical starting point.
Supplier: prepare the transaction and packing records
The supplier usually prepares the commercial invoice and packing list using the actual goods and transaction information. Ask for drafts early enough to review, followed by final versions once packing has been confirmed.
Buyer and importer: verify the transaction and import arrangements
The buyer should check that the purchase order, quantities, prices and seller details reflect what was agreed. Identify the entity acting as importer and confirm the relevant EORI and other details with that entity and the customs representative.
The importer and consignee can be different parties. A delivery address or recipient’s name does not, on its own, establish who is responsible for the import.
Freight forwarder and customs representative: check their respective requirements
The forwarder can check the shipment information needed for the agreed transport booking. The appointed customs representative should confirm the information, supporting documents and authority required for the declaration.
The forwarder and customs representative may be different organisations. If a third party is appointed to make the declaration, confirm its role and authorisation, and agree who will provide and approve the final information. Whether Yunxi Freight or a partner carries out a particular task depends on the arrangements agreed for the shipment.
A freight service described as DDP does not mean the buyer can ignore document accuracy or the identity of the importing party. For the separate comparison of responsibilities, see DDP vs DAP shipping.
What else may be needed for a Great Britain import?
The commercial invoice and packing list are starting points, not a complete list of requirements for every product.
Information such as a commodity code, EORI, licence or valuation evidence may be needed for the import declaration or document handover. Do not assume that every item must be printed on the packing list.
HMRC’s full import declaration guidance identifies information such as the commodity code, parties, type and amount of goods, packaging, transport, currency, valuation method, and licences or certificates where applicable. Depending on the transaction, the customs representative may also ask for a purchase order, transport document, freight charges or other valuation evidence.
Before booking, confirm:
- The goods: an accurate description, material, intended use and appropriate commodity code.
- The transaction: actual price and currency, plus supporting agreements or charges relevant to valuation.
- Origin: the applicable origin information and evidence for the goods.
- The importer and representative: the legal entity, applicable EORI and arrangements for representation.
- Product requirements: whether the goods need a licence, certificate or other evidence.
- The route and destination: whether the shipment enters Great Britain directly or involves Northern Ireland or another route requiring separate checks.
Great Britain means England, Scotland and Wales. Northern Ireland can require different customs arrangements; ask the appointed representative to assess the actual route and goods. An EORI is a customs identification number, not proof of VAT registration or product compliance.
For ocean freight, the choice between China to UK container shipping options is a separate decision from whether the documents are accurate. Confirm the final packed measurements for the selected booking.
A five-step document check for your next China order
Use this sequence before handing over your final shipping documents:
- Identify the parties. Confirm the seller, buyer, importer, consignee and appointed customs representative.
- Check the goods and transaction. Reconcile product descriptions, SKU quantities, prices and currency with the purchase order and actual transaction.
- Check the physical shipment. Compare carton count, contents, marks, weights and dimensions with the final packed goods.
- Confirm additional requirements. Ask the customs representative about commodity codes, origin information, valuation evidence, licences and any other documents applicable to the goods.
- Control the final handover. Record the final versions, send them to the relevant parties and communicate any later changes promptly.
If a document changes after it has been sent, tell the parties using it. Do not assume that correcting the supplier’s copy automatically updates a booking or customs declaration. Agree the necessary next step with the relevant provider or representative.
Frequently asked questions
Is a commercial invoice the same as a packing list?
No. A commercial invoice focuses on the transaction and value; a packing list describes the physical shipment. Information that appears in both should agree or be capable of being reconciled.
Who normally prepares the invoice and packing list?
The Chinese supplier commonly prepares them, but the buyer, importer, forwarder and customs representative each need to check the information relevant to their role. Confirm responsibilities before dispatch.
Does every line of the invoice have to look identical to the packing list?
No. The documents can present information differently. The important point is that product references and quantities can be reconciled, including any partial shipment or mixed carton.
Can a pro forma invoice replace the commercial invoice?
Do not assume that it can. A pro forma document may describe a proposed transaction rather than the final one. Ask the customs representative what evidence is appropriate for the actual shipment and transaction.
Are these two documents enough for UK customs?
Not necessarily. The declaration and supporting evidence depend on the goods and import arrangements. A commodity code, transport information, valuation evidence or product-specific documentation may also be needed.
What should I do if the documents change after booking?
Tell the supplier, forwarder and customs representative which information has changed and provide the revised documents. Ask the relevant party whether the booking, declaration or supporting records need to be amended. The appropriate action depends on what changed and the stage of the shipment.
Prepare the final document handover
A clear invoice and packing list give each party a consistent starting point. Before dispatch, resolve discrepancies with the supplier, identify the importer and customs representative, and make sure the agreed final versions reach everyone who needs them.
To discuss a China-to-UK shipment, provide the product description, packed quantities and dimensions, supplier location, intended UK destination and any known import arrangements. Yunxi Freight can review the proposed transport requirements and discuss the agreed scope of support.
