EU customs guides for importers

Last updated 26 August 2026

Clear answers to some of the customs questions importers search for most often. Every guide starts with the practical answer, links to primary EU sources and says where the facts still need professional judgement.

Current rule

EU €3 customs duty on low value parcels

What changed in July 2026, how the per item charge works and why it is not the same as the proposed handling fee.

Calculation

How to calculate EU import duty and import VAT

A worked calculation covering customs value, tariff rate, freight, origin and the import VAT base.

Classification

HS code, CN code and TARIC code

The difference between six, eight and ten digit codes, plus a safer process for finding the right EU classification.

Registration

What is an EORI number and how do you check one?

Who needs an EORI, where to request it, how to use the official validator and what a valid result does not prove.

Read the guide

Valuation

Customs value, freight, insurance and Incoterms

Why the invoice total is not always the customs value and how to find the costs that need review.

Read the guide

Audit

EU customs declaration audit checklist

A field-by-field review of classification, origin, value, measures, quantities, evidence and duty calculations.

Recovery

EU customs duty recovery

What importers can actually claim, the normal three-year application period and the evidence a recovery case needs.

How to use the guides

Start with the question in front of you. Use the calculation, code, EORI and valuation guides for a single issue. Use the audit checklist when you are organising a wider review, and the duty recovery guide only after you have found a possible overpayment.

The guides are general information. They do not replace the law, national customs procedures or advice from a competent customs professional.

Check one declaration

Run the free declaration check to see how The Declarant separates findings, calculations and missing evidence before a broader historical review.
