Beta · sample data

During the beta these results come from a sample reference dataset (tax rates, HS catalog, regulations, screening, sanctions and PEP lists), not the official sources. Use them to build and test your integration, not for customs declarations or compliance decisions. API responses carry x-tariffapis-data: sample.
