What Is a Packing List and Do You Need One for Every Export?
Published 8 July 2025 · 4 min read
The packing list is one of the three core export documents for any commercial UK shipment — alongside the commercial invoice and, for EU shipments, the statement of origin. Despite its name, it isn't just a list of what's in the box. It's a critical customs document that tells border officials how to physically verify the consignment against the declared value. Here's what it needs to contain and when you need one.
What a Packing List Is — and Isn't
A commercial invoice records the financial transaction — what was sold, for how much, to whom, under what terms. A packing list records the physical contents of the shipment — what's in each box, how heavy it is, how many packages there are, and what the dimensions are.
The two documents are complementary. Customs use the commercial invoice to assess duty and VAT; they use the packing list to verify that the physical shipment matches the declared contents and weight. If the packing list says 12 boxes weighing 45kg total and only 10 boxes arrive at the destination warehouse, that discrepancy is documented and traceable.
A packing list is not a substitute for a commercial invoice. Both are required for commercial shipments — not one or the other. See the guide to essential UK export documents for a full overview of what each document does.
What a Packing List Must Include
A well-structured packing list contains the following fields:
- Exporter details: business name, address, and EORI number
- Consignee details: recipient name and delivery address
- Invoice reference number: the packing list must reference the corresponding commercial invoice
- Package count and type: how many boxes, pallets, or other packaging units; what type of packaging is used
- Contents per package: what is in each box or unit — quantity, description, and HS/commodity code
- Net weight per item or line: the weight of the goods themselves, excluding packaging
- Gross weight per package: the total weight including packaging
- Dimensions: length, width, and height of each package in centimetres
- Total gross weight and volume: the sum of all packages
For multi-package shipments, each package should be numbered and its contents listed separately. A shipment of 5 boxes where boxes 1–3 contain product A and boxes 4–5 contain product B should be listed as such — not as a single combined entry.
When Do You Need a Packing List?
For all commercial international shipments, you should produce a packing list. There is no official minimum value threshold — even a small parcel sent commercially should have one. In practice, courier services often don't ask for a packing list on small single-item parcels, but having one protects you if the shipment is stopped for inspection or a dispute arises about the contents.
Packing lists are essential for:
- Multi-item shipments where the commercial invoice lists several line items
- Freight shipments (air or sea) where the forwarder needs weight and dimension data
- Shipments to countries with strict customs inspection regimes
- Any shipment where the goods and the declared value need to be independently verifiable
How Customs Use the Packing List
When a shipment is selected for physical inspection, customs officers compare the packing list against the commercial invoice against the actual contents of the boxes. Discrepancies — a higher quantity than declared, goods not matching the description, weights that don't reconcile — trigger further investigation and can result in the shipment being held, re-examined, or seized.
A complete, accurate packing list is not just a formality. It's your evidence that your declaration was honest. Missing or vague packing lists are among the most common export documentation mistakes UK businesses make — and they're entirely preventable.
Packing List vs Commercial Invoice: a Quick Comparison
| Document | What it records | Used for |
|---|---|---|
| Commercial invoice | Financial transaction — price, buyer, seller, terms | Duty assessment, payment |
| Packing list | Physical contents — weights, dimensions, package count | Customs verification, freight |
Generate Both From One Entry
The most efficient approach is to produce both documents simultaneously from the same data. ClearDocs does exactly this — you enter your exporter and consignee details, add line items with quantities, weights, and HS codes, and it generates a correctly formatted commercial invoice and packing list in one step. The same data also produces your statement of origin for EU shipments. No re-keying, no risk of the two documents being inconsistent.
