Short answer: An HS code is a standardized product classification used by customs authorities to identify goods and determine duties, restrictions, and reporting requirements.
What the digits mean
- The first six digits come from the international Harmonized System.
- Destinations can add digits for their own tariff schedules and statistical needs.
Why Shopify teams need SKU-level codes
- Material, function, and construction can change classification.
- A single generic code across a catalog can produce wrong rates and declarations.
How to maintain HS data
- Keep the evidence behind each classification.
- Recheck when the product, material, supplier, or destination changes.
