Canada’s H.S. codes and duty rates are contained in a schedule to the Customs Tariff. Every year, Canada publishes online the Departmental Consolidation of the Customs Tariff. This is chapter-by-chapter files (html and pdf files) with Canada’s tariff rates and a column setting out tariff reductions under Canada’s various free trade agreements. The 2018 Version includes the newly implemented Canada-EU CETA (CEUT abbreviation) and Canada-Ukraine Free Trade Agreement (UAT abbreviation). If you know the H.S. tariff classification number, you can look up the applicable tariff rate for goods imported into Canada.
