Coming soon

Sign-up for the newsletter to keep informed of the new features to be added to the platform. We will shortly be publishing the Explanatory Notes and Classification Opinions for the HS 2022. We will also be presenting other WCO standards, such as the Revised Kyoto Convention, in a user-friendly way.

Licences and application programming interface (API) solution

Organizations and companies wishing to incorporate the features offered by WCO Trade Tools into their applications and online services can do so thanks to our API solution or our licence options. You may, for example, already have an application to calculate Customs duties and wish to offer your customers a search engine to find their way around the HS (API solution) or to give them access to HS Legal Notes, Explanatory Notes or Classification Opinions (API and Licence options). By connecting with our platform, you simplify the work required to do so.
