Where the numbers come from, under what licence, and how often they are refreshed.
Last updated
Tollmark holds no opinion about what duty should be. Every rate on this site is ingested from an official tariff source, kept with the legal instrument it came from and the date it took effect, and re-checked nightly. The raw response behind every figure is archived, so any published number can be traced back to the exact bytes that produced it.

Northern Ireland: rates, not totals
Northern Ireland is charged the EU's Common External Tariff rather than the UK Global Tariff, so its duty can differ from Great Britain's on the same goods. Across the commodity codes this site covers the two agree far more often than they differ, and where they differ the difference is shown on the relevant category page.
We publish those rates and no Northern Ireland totals. Its customs relief follows EU rules — from 1 July 2026, €3 per item on consignments under €150 of intrinsic value — while its VAT follows UK rules, because Northern Ireland remains part of the UK VAT system. Those are euro figures on a sterling territory, and this site does not convert currencies inside a quote. Leaving the relief out would overstate every small parcel; converting it ourselves would invent a number. So the rates are published and the total is not.
Goods moving from Great Britain to Northern Ireland are a different regime again, and nothing here describes it.
What we could not store
Some things an upstream source publishes do not fit our model, and we record those rather than quietly dropping them. Two cases recur:
- Preferences granted to a group of countries. The UK grants some preferential rates to blocs rather than to individual states. Our records hold one country per rate, so a group preference is logged as a coverage gap instead of being flattened to an arbitrary member.
- Headings whose commodity codes disagree. Where two ten-digit codes under one six-digit heading carry different rates, that heading has no single true rate. We publish nothing for it rather than picking one.
