Business PickupFor foreign companies, navigating Canada’s trade and tariff framework is complex. Misunderstanding tariff regulations presents serious financial and operational risks, from unexpected costs and delays to penalties. Here, we’re sharing a clear, practical overview of key tariff rules, compliance obligations, and cost-saving strategies to support smooth customs clearance and confident cross-border trade.
Understanding Canadian tariffs: The basics
Tariffs are a type of tax that governments apply to goods entering from another country. When these goods cross borders, the importer of Record (IOR) pays the tariff to the customs agency. In addition, Canadian-imposed tariffs, such as those issued as a countermeasure to the U.S. tariffs imposed on Canadian goods, can also affect costs. (As of September 1, 2025, the Government of Canada’s 25% tariff only applies to auto imports, steel, and aluminum products originating from the U.S.)
Any business involved in importing or exporting goods must also be familiar with the World Customs Organization’s Harmonized Description and Coding System (HS), which classifies products using a 6-digit code. The HS is a basis on which tariff schedules and export codes are created, and allows everyone involved in international trade to find the appropriate tariff rate.
Tariffs can be calculated as a percentage or as a fixed fee on the value for duty of imported goods, as determined by the good’s HS code, as well as the origin and trade agreements. Typically, the formula is:
Duty = Value for Duty (VFD) x Duty Rate, plus other applicable taxes (such as GST)
For example, a US good with a value for duty of $50 would be multiplied by the 25% tariff for a total surtax of $12.50
In addition to the HS, businesses should anticipate charges such as the Goods and Services Tax (GST), a federal value-added tax at a rate of 5%. This tax is applicable across all of Canada, except provinces that have adopted the Harmonized Sales Tax. Provincial sales tax (PST) is also levied on the sales of goods and services in British Columbia, Saskatchewan, and Manitoba, with rates varying by province.
Key compliance requirements for importers
To legally import goods into Canada, international businesses must meet several mandatory compliance requirements enforced by the Canada Border Services Agency (CBSA). Failure to comply can result in shipment delays, monetary penalties, retroactive duty assessments, or seizure of goods. For example, importers are responsible for assigning the correct HS tariff classification code to each product, which determines applicable duty rates, eligibility for trade agreement benefits, and regulatory controls or restrictions.
Goods must also be accurately declared using the transaction value method, meaning the price actually paid or payable. Under-declaring value can lead to penalties and back-dated duty charges. Importers must therefore include:
- Assists such as molds, tooling, or design work
- Royalties or licensing fees tied to the goods
- Packing and transportation costs to the point of direct shipment to Canada
Additionally, importers must correctly identify the country of origin, which affects duty rates, trade agreement eligibility, and labeling and marking requirements. Importantly, origin is based on rules of origin, not simply where goods were shipped from. Incorrect origin claims can invalidate preferential tariff treatment. Complete and accurate documentation should include the following:
- Commercial invoices with full product descriptions and values
- Bills of lading or air waybill
- Certificates of origin (if claiming preferential tariffs)
- Import permits or licenses, where applicable
Proper recordkeeping is also critical for businesses. According to the CBSA, all documentation should be retained for a minimum of six years.
Trade agreements and tariff reduction opportunities
While Canada’s tariff regulations can be challenging to manage, the good news is that the country has major trade agreements designed to promote fairer trade and freer markets by reducing tariffs and establishing guidelines. Some examples include:
- United States-Mexico-Canada Agreement (CUSMA)
- Comprehensive Economic and Trade Agreement (CETA) with the EU
- Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP), connecting Canada to North, South, and Asia-Pacific markets.
If your goods qualify, your business may benefit from reduced or zero tariffs. With that in mind, there are important pitfalls to avoid, including assuming eligibility without proper documentation and misunderstanding rules of origin. Be sure to verify eligibility long before your goods are shipped.
In addition to leveraging applicable fair trade agreements, there are other practical ways your business can reduce its tariff exposure. For example, determining the correct tariff classification from the outset will allow you to sidestep potentially costly fees and penalties. Further, pursuing strategic supply chain planning can also help you avoid unexpected costs and delays.
