UK Tariff Code Lookup & Duty Calculator

The UK Global Tariff (UKGT) is the UK's own tariff schedule for imported goods, introduced on 1 January 2021 after Brexit. It replaced the EU's Common External Tariff (CET) and is maintained by HM Revenue & Customs (HMRC). It applies MFN duty rates to imports from most countries, with preferential rates available under FTAs such as the UK-EU Trade and Cooperation Agreement (TCA).

The 6-digit HS code is the international Harmonized System standard used worldwide to classify products (e.g. 0101.21 for pure-bred breeding horses). The UK extends this to 10-digit commodity codes (e.g. 0101.21.00.00) for import declarations, adding country-specific digits that carry the applicable UKGT duty rate and statistical reporting requirements.

This tool currently displays the HS 6-digit base layer — the international classification hierarchy shared by all 97 chapters. The HS base defines the product classification but does not carry the country-specific duty rate. UKGT MFN duty rates, preferential rates, and the full 10-digit commodity codes are being imported from HMRC's Trade Tariff service and will be displayed here in Q3 2026.

UK customs duty is typically calculated on the CIF value (cost + insurance + freight) of the goods, multiplied by the applicable UKGT duty rate. Import VAT (20% standard rate) is then applied on top of the CIF value plus the customs duty. Some goods attract excise duty (alcohol, tobacco, hydrocarbon oils). Our calculator estimates the customs duty portion using a manually entered rate.

The official source is the HMRC Trade Tariff service at gov.uk/guidance/uk-global-tariff. It provides the full UKGT schedule including 10-digit commodity codes, MFN duty rates, preferential rates, anti-dumping measures, and suspensions. Always verify current rates with HMRC before filing import declarations.
