Customs paperwork support for UK importers and exporters

Key takeaways

Importing and exporting from the UK means repeating the same paperwork for every shipment: commodity codes, commercial invoices, packing lists, origin information, an EORI number and instructions to your customs agent. The declarations themselves are usually made by a customs broker. The preparation and record keeping around them are repetitive admin that a routine keeps consistent.

• You need an EORI number to move goods in or out.
• Commodity codes decide duty; keep them consistent.
• Commercial invoices and packing lists for every shipment.
• Keep customs records for the required period.

What customs paperwork repeats on every shipment?

Most of the paperwork follows the same template for every shipment, with the details changed. Errors in codes, values or origin are what cause delays and unexpected duty.

• Commercial invoice with values and terms.
• Packing list with weights and quantities.
• Commodity codes for each product.
• Origin information for preferential tariffs.
• Instructions and documents to your customs agent.

How do you keep codes and values consistent?

Keep a product master list with each item's commodity code, origin and description, approved once by someone competent or your customs adviser. Every shipment then draws from the list rather than being worked out again. HMRC's step-by-step guides for importing and exporting set out what you need.

• Single source of truth: one place for each business fact
• Decision tables: turn judgement calls into clear rules

What does customs admin take?

In an illustrative example, an exporter sending 40 shipments a month spends about 30 to 45 minutes each on invoices, packing lists and broker instructions: 20 to 30 hours a month. These are example figures. A held shipment costs storage, delay and an unhappy customer, so accuracy is worth more than speed.

What should stay with you or your broker?

Classification decisions on new products, valuation questions, origin claims and the declarations themselves should stay with you, your customs broker or an adviser. You remain responsible for the accuracy of the information. A support team prepares documents from the approved product list and flags anything new.

• Rule-based vs judgement tasks: what to hand over

What does this look like in practice?

A pattern we see: the same product is shipped under different codes by different staff, causing queries and inconsistent duty. A single product master with approved codes fixes it.
