Customs Compliance Checklist for UK Importers and Exporters

Why a Customs Compliance Checklist Matters

Customs compliance isn’t a one-off task — it’s an ongoing commitment that touches every stage of your import and export operations. From commodity classification to record-keeping, HMRC expects businesses to maintain robust systems. A single compliance failure can result in delayed shipments, financial penalties, or even seizure of goods. According to GOV.UK customs guidance, businesses must take proactive steps to ensure full compliance with UK border requirements.

This checklist covers the essential areas every UK importer and exporter should review regularly.

EORI Number and Registrations

• Confirm you have a valid UK EORI number (starting with GB) — required for all customs declarations.
• If trading with the EU, check whether you also need an EU EORI number (required if you make declarations in an EU member state).
• Ensure your EORI is linked to your correct VAT registration.
• Review authorisations for any simplified procedures (e.g., CFSP, EIDR) and confirm they remain valid.

Commodity Classification

• Verify that commodity codes for your top-selling products are accurate and up to date.
• Review whether any codes have changed in the latest UK Trade Tariff update (updates occur periodically).
• Consider applying for Binding Tariff Information (BTI) rulings on high-volume or high-value products for certainty.
• Cross-check that codes on commercial invoices match those used in customs declarations.

Misclassification is one of the most common compliance failures. If you need assistance, our team at agencjacelna.uk can review your product classifications.

Customs Valuation

• Ensure you are using the correct valuation method (Method 1 — transaction value — applies to most imports).
• Include all required adjustments: freight, insurance, royalties, assists, and packing costs.
• Use HMRC’s published exchange rates for currency conversions, not spot rates.
• If you import from related parties, document your transfer pricing methodology.

Origin and Preferential Rates

• Determine the country of origin for each product line — this affects duty rates and trade remedy measures.
• Check whether any preferential trade agreements (e.g., UK–EU TCA, UK–Japan CEPA) apply to reduce or eliminate duty.
• Obtain and retain valid origin declarations or certificates before claiming preferential rates.
• Monitor changes to Rules of Origin under each agreement, as they can be amended.

Import and Export Licences

• Identify whether any of your products require import or export licences (e.g., dual-use goods, agricultural products, controlled substances).
• Apply for licences before shipment — retrospective licensing is rarely available.
• Maintain a register of all licences held, including expiry dates and usage limits.

Record-Keeping

• Retain all customs documentation for a minimum of six years, as required by HMRC.
• This includes customs declarations, invoices, transport documents, origin certificates, licences, and correspondence with customs agents.
• Store records securely and ensure they are easily retrievable in the event of an audit.

Duty Relief and Special Procedures

• Review whether you qualify for any duty relief schemes — such as Inward Processing, Outward Processing, Temporary Admission, or End Use.
• Ensure authorisations are active and conditions are being met, including discharge deadlines.
• Report accurately on goods entering and leaving special procedures.

Security and Safety Declarations

• Confirm that Entry Summary Declarations (ENS) and Exit Summary Declarations (EXS) are being filed where required.
• Verify that your safety and security data is accurate and filed within the required timeframes.
