Do You Need a Tariff Number to Ship to Canada?

Shipping goods across the Canada–U.S. border (or from anywhere overseas) means navigating more than just logistics. One of the most important requirements in international trade is providing the correct tariff number for each product. But why is this number necessary, and what could go wrong if you don’t use one? Here’s what every exporter needs to know about tariff numbers for shipping to Canada.

What Is a Tariff Number?

A tariff number, also known as an HS (Harmonized System) code, is a standardized numerical code assigned to every type of product that is imported or exported internationally. The World Customs Organization developed the Harmonized System, which categorizes goods into chapters, headings, and subheadings according to their nature, composition, and intended use.

For Canadian imports, the HS code is used along with Canada’s own tariff classification structure. Most commonly, you’ll see eight or ten-digit numbers, where the first six digits align with international norms, and the subsequent digits provide Canadian-specific detail.

Why Are Tariff Numbers Necessary for Canada?

1. Legal Requirement

Canada Border Services Agency (CBSA), the authority responsible for customs in Canada, mandates that all imported goods are classified and declared using the correct tariff number. Failing to provide an accurate HS code can result in delays, penalties, or even seizure of your shipment.

2. Helps Determine Duties and Taxes

The tariff number determines how much duty and GST/HST is owed on your shipment. Different goods attract different tax rates and duty amounts. Without a correct HS code, customs officials cannot accurately assess the obligations, potentially costing you extra money or causing disputes with customers.

3. Identifies Import Restrictions and Regulations

Certain goods are subject to special requirements, restrictions, or permits under Canadian law. The HS code helps authorities flag goods that need additional paperwork or may be prohibited.

4. Enables Efficient Processing

Including the correct tariff number on your commercial invoice and customs declaration helps ensure your shipment moves quickly through Canadian customs. It minimizes risk of inspection, secondary review, or delays, all of which can impact your customer experience and business reputation.

What Happens if You Provide the Wrong Tariff Number?

Mistakes or omissions with tariff numbers can cause a range of problems, including:

• Shipping delays: Goods might be held at the border while authorities verify product classification.
• Fines or penalties: CBSA can impose administrative monetary penalties for misclassification.
• Incorrect duties: You may end up overpaying or underpaying duties and taxes. Underpayment could lead to retroactive assessments, additional costs, and stressful audits.
• Seizure of goods: Severe errors or misclassifications could result in shipment seizure.
• Loss of trusted trader status: Repeated infractions can affect your reputation and eligibility for customs privileges.
