The UK has launched two databases replacing the EU TARIC and the Market Access Databases. Both tools are available on gov.uk and similar to the EU tools detail product-specific and country-specific information.
Trade with the UK
Similar to the EU TARIC it provides information on imports into the UK such as duty rates and imports requirements.
Check How to Export Goods
Similar to the EU Market Access Database, this tool provides UK exporters with information on access to foreign markets such as import duty rates and import requirements. It also covers export requirements from the UK.
