Post-Brexit trade requires precise paperwork, correct tax IDs, and an understanding of new rules. Mistakes lead to fines, delays, and returned shipments. This practical guide outlines the essential steps for UK businesses to clear EU customs reliably.

1. EORI Numbers: Ensure You Have the Correct Ones

The Problem:
Customs declarations are rejected if the wrong EORI (Economic Operator Registration and Identification) number is used. A UK EORI is not always valid for importing into the EU, causing holds and fines.

The Solution:

• Secure both a UK EORI and an EU EORI (if you are the importer of record into an EU member state).

• Include the correct EORI on every commercial invoice and customs declaration.

• Integrate EORI numbers into your order and supplier templates to prevent errors.

Client Case:
A UK SME faced repeated delays at Rotterdam because shipments only listed a UK EORI. After registering for an EU EORI and updating their documentation, clearance times returned to normal.

2. VAT & IOSS: Manage EU Distance Selling Rules

The Problem:
Incorrect VAT treatment causes parcel holds, unexpected fees for your customers, and penalties. The EU strongly encourages the use of the IOSS scheme for distance sales.

The Solution:

• Register for the Import One-Stop Shop (IOSS) if you sell low-value B2C goods to the EU. Include your IOSS number on customs declarations to prevent VAT collection at the border.

• For non-IOSS shipments, clearly state delivery terms (DDP or DAP) so customers know if VAT is paid upfront.

• Stay updated on EU VAT reforms to ensure your checkout and tax settings remain compliant.

Client Case:
An online retailer had a high rate of delivery refusals and returns due to unexpected VAT charges. After implementing IOSS and displaying all taxes at checkout, refused delivery rates dropped significantly.

3. Documentation & Compliance: Avoid Costly Rejections

The Problem:
Incomplete invoices, wrong HS codes, or missing product certificates trigger inspections, rejections, and fines.

The Solution:

• Standardize your commercial invoices. They must include: accurate HS codes, country of origin, full consignee details, EORI numbers, Incoterms®, and weights.

• Maintain a library of product compliance documents (e.g., safety certificates, CE/UKCA marks) and provide them to your broker in advance.

• For regulated goods (electronics, cosmetics, food), ensure all market approvals and safety documentation are correct and attached.

Client Case:
A cosmetics importer eliminated repeated customs reassessments and inspections by replacing inconsistent supplier invoices with a single, detailed template.

4. Safety & Security Declarations: The New Filing Reality

The Problem:
Missing or incorrect safety and security filings can stop your goods at the border and result in penalties.

The Solution:

• Confirm who is responsible for filing these declarations—your carrier, forwarder, or your company—and ensure they are submitted before arrival.

• Double-check that the data in these filings (e.g., weight, description) perfectly matches your commercial invoice and transport documents (Bill of Lading/Air Waybill).

Client Case:
A manufacturer’s export to the EU was delayed due to a missed exit summary declaration. They implemented a new checklist for suppliers and forwarders, ensuring all data was provided for timely filing, which resolved the issue.

5. Northern Ireland: Navigate the Windsor Framework

The Problem:
Northern Ireland has unique rules. Using the wrong customs lane or paperwork can block your goods and lead to fines.

The Solution:

• Familiarise yourself with the Windsor Framework and its schemes for moving goods between Great Britain, Northern Ireland, and the EU.

• Use the correct duty-waiver schemes and labelling requirements for retail movements.

• Consider working with a broker who has specific expertise in NI-EU trade flows to ensure correct declaration types.

Client Case:
A GB wholesaler misrouted goods to the Republic of Ireland via NI, causing delays. After adopting NI-specific checklists and consulting a specialist broker, they streamlined their cross-border movements.
