Sources and method

Every duty rate on this site is copied from the official customs tariff of the destination: the US Harmonized Tariff Schedule, the UK Trade Tariff, the EU Combined Nomenclature, the Canadian Customs Tariff and the Japanese tariff schedule. Tax and exemption rules come from the official pages of the customs and tax authorities.

For each product group we take the HS6 code and read every tariff line under it. A rate is turned into a number only when it is a plain percentage ("12%", "Free"); a specific or compound duty (for example per kilogram plus a percentage) is not converted and is flagged. The range is the lowest to the highest plain rate among the lines. Japan applies the lower of the General and the WTO rate, as Japan Customs states. 400 tariff lines are recorded, each with a verbatim excerpt from the official page and its URL.
