Canada HS Codes: Complete Guide to Tariff Classification

Cracking the Code: A Guide to Canada’s Harmonized System (HS) Codes

Think of an HS code as the universal barcode of global trade. Instead of customs officers in every country needing to read descriptions in multiple languages—which could lead to translation errors or confusion—they simply look at a standardized set of digits that instantly tells them what is inside a package.
