We’ve updated the API documentation to include a number of new endpoints:
For listing the country and country groups used by the tariff, which will be needed after EU Exit.
The data behind the A-Z browsing on the trade tariff.
Added more data in the commodity code response, so that the duty expression is exposed by each component part (previously it was one string) so that the values can be extracted.
Clarified that the search quota filters for status use underscore no spaces.
Let me know if you have any issues or need more data in the TARIFF API for your use case.
