Compliance Management for UK Importers and Exporters
Customs compliance means your declarations are right the first time, and any errors are corrected promptly and within the time limits. That covers the commodity code, the customs value, the origin claim, the licences and certificates, and the records behind every entry. Tevolution helps UK importers and exporters, and overseas companies selling into the UK, find and fix gaps before they turn into duty demands, penalties or delays at the border.
Why customs compliance matters after clearance
Most businesses judge customs by one question: did the goods arrive? But a released shipment is not a closed file. HMRC can review declarations after the goods have been cleared, and errors in classification, valuation or origin can lead to back-dated duty and import VAT, interest and penalties.
The risk grows quietly. One wrong commodity code, repeated on every shipment for two years, becomes a large and unexpected bill. So does a preference claim that the supplier’s origin paperwork cannot support.
The three pillars: classification, valuation and origin
Every customs declaration rests on three decisions. Get them right and most other compliance issues fall into place.
Tariff classification
The commodity code decides the duty rate, the import VAT treatment, and whether licences, health certificates or other controls apply. We check codes against the UK Global Tariff and the product’s real composition and use, not just the supplier’s invoice description. Where a code is disputed or unclear, we can help you apply to HMRC for an Advance Tariff Ruling.
Customs valuation
Duty is charged on the customs value, which is not always the invoice price. Freight, insurance, royalties, assists and related-party pricing can all change it. We review how your values are built so you neither overpay nor underdeclare.
Origin and preference
Preferential origin under the UK’s trade agreements, including the Trade and Cooperation Agreement with the EU, can reduce duty to zero. But the claim must be supported by the rules of origin and the right evidence. We check that your claims hold up and that your suppliers’ statements on origin are valid.

Customs compliance FAQs
What is customs compliance?
It is the process of making sure your imports and exports meet UK customs law: correct classification, valuation and origin, the right licences and certificates, accurate declarations and complete records.
Who is responsible if a declaration is wrong?
The importer or exporter named on the declaration. If a customs agent acts as an indirect representative, the agent can also be liable for the duty. Either way, the business carries the risk, which is why regular checks matter.
What happens in an HMRC customs audit?
HMRC reviews a sample of your past declarations against your commercial records, and may ask how you classify, value and claim origin for your goods. Errors can lead to back-dated duty and VAT, interest and penalties. Read more in our guide to customs audits.
Can I correct a mistake on a past declaration?
Yes. Errors can usually be amended or disclosed to HMRC, and overpaid duty can often be reclaimed, subject to time limits. It is better to correct an error yourself than to wait for HMRC to find it.
For a full explanation, read our Customs Compliance page.
Do you only work with UK companies?
No. We also act for overseas companies importing into the UK, including as indirect representative.
