To help users of the Online Trade Tariff APIs, we are augmenting the API documentation.
We have focussed on:
-
detailed documentation of the commodities API. The commodities API is the most commonly used API and contains most of the data that is needed to pull commodity and measure data into external applications.
-
a list of commonly requested reference data, such as measure types, measure type series, condition and action codes.
If you have any feedback, queries or issues, or suggestions for further documentation, please contact the team on hmrc-trade-tariff-support-g@digital.hmrc.gov.uk.
