There are 3 types of tariff rates that are used to calculate duty payable on imported goods. Products where no tariff is payable are duty free items.
For imports into Canada, Canada Border Services Agency (CBSA) publishes a comprehensive manual with duty rates for over 8,000 products. That reference document is called the Customs Tariff.
Ad Valorem Duty Rates
The most common type of duty rate is the ad valorem duty calculated based on a percentage of an imported good’s value for duty.
