The first six digits of the code are internationally standardized, while the final digits are country-specific. In Canada, tariff codes typically consist of 8 or 10 digits.
Why HTS Code Lookup Is Important in Canada

How to Perform an HTS Code Lookup in Canada
Here’s a step-by-step guide on how to find the correct HTS code for your products:

2. Identify Key Product Details
Before searching, gather detailed product specifications including:
Material or composition
Intended use
Product packaging
Manufacturing process
Country of origin
These details influence the code assignment. For example, cotton clothing and synthetic garments fall under different codes even if they look similar.
3. Review Notes and Explanations
The Customs Tariff tool provides additional legal notes and chapter descriptions. These help clarify classifications when multiple codes appear similar.
4. Request a Binding Ruling (Optional)
If you're unsure, the CBSA allows importers to request a National Customs Ruling (NCR). This is a legally binding decision on the correct classification and can save time and money in the long run.
HTS Code Structure Example
Let’s take an example of a product – men's cotton shirts.
6105.10 – International HS code (shirts, of cotton)
6105.10.00.00 – Full Canadian HTS code
This code determines the duty rate, which could be duty-free under CUSMA if made in the U.S. or Mexico.
HTS Code Lookup Tips
✔️ Always use Canadian sources. U.S. and Canadian codes can differ after the first 6 digits.
✔️ Avoid guessing. Even a small error can change duties or trigger investigations.
✔️ Keep codes updated. CBSA revises tariff schedules annually or in response to trade agreements.
✔️ Consult a customs broker for large or complex shipments.
