HS code stands for Harmonized Commodity Description and Coding System. It is an international customs classification system which allocates a unique 6-digit HS code to each group of products.
HS codes consist of 6 at least digits and are broken down into: Chapters (first 2 digits), Headings (first 4 digits) and Subheadings (full 6 digits). The HS codes are further subdivided into 7- to 12-digit items depending on the country (also referred to as commodity codes and national tariff lines). They are used by customs to classify the shipped product. That way, they can accurately calculate taxes and duties and apply necessary restrictions.
