What is a Harmonized System code in Shopify?
A Harmonized System (HS) code is the customs tariff number Shopify stores on each product so Markets can calculate duties and pre-fill international shipping forms. Without accurate HS codes, cross-border orders risk holds, reclassification, and unexpected duty bills for your customers.
