Where the numbers come from, under what licence, and how often they are refreshed.
Last updated
Tariff rates come from the official sources listed below. Country-level rules and carrier fees are maintained separately, so a tariff refresh does not refresh every input to an estimate. Follow the source links and read the dates attached to the particular rate or fee you are using.
The importer stores raw source responses and links new records to source evidence. Some older records have less complete evidence. An archive key identifies internal evidence; it is not a public guarantee of independent review or a complete history of every earlier figure.

Northern Ireland: rates, not totals
Tollmark uses the Northern Ireland tariff feed for selected comparisons with Great Britain. A comparison identifies differences in the published tariff rates, not the complete charge for a particular parcel.
We do not calculate Northern Ireland landed totals. The model does not resolve the applicable movement, relief and VAT arrangements for that destination. For the VAT context, see the official guidance: Northern Ireland remains part of the UK VAT system. A missing total is a limit of Tollmark's coverage, not a statement that no VAT or duty is payable.
Goods moving from Great Britain to Northern Ireland are a different regime again, and nothing here describes it.
How tariff coverage is limited
Not every distinction in the tariff can be resolved at a six-digit heading. Two important limits are:
- Preferences granted to a group of countries. The UK grants some preferential rates to blocs rather than to individual states. Our records expand a group preference into its member countries, preserving the agreement and excluding countries the measure does not cover. If the source does not provide usable membership, we record a coverage gap. These comparison records do not establish that a parcel qualifies: the live calculator uses the ordinary tariff.
- 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.
Country rules and carrier fees
VAT defaults, valuation rules and relief thresholds are stored as country rules. Carrier fees are taken from published price lists and stored with their source and check date. These inputs are not automatically refreshed by the nightly tariff job. The carrier table on a category page shows the source for the fee it lists; verify the service and price before ordering.
A calculation date is the date the model ran. It must not be read as the last successful check of every source. Scheduled checks, review and publication can be delayed. Read the methodology for how a default rate or typical carrier fee affects the result.
Calculator coverage
The calculator covers Great Britain and Norway for the commodity codes we have ingested. Northern Ireland supplies tariff comparisons only. Other destinations and commodity codes show a coverage gap until their data is loaded and checked. Browse the published categories to see the available source-backed pages.

If you think a figure here is wrong, report the page and source. The corrections log records documented corrections and its own coverage limits.
