A standardised international code used to classify traded products for customs and tariffs.
An HS Code (Harmonized System Code) is a standardised numerical code used worldwide to classify traded goods. Developed by the World Customs Organization, the Harmonized System assigns every product a six-digit code that customs authorities use to determine duty rates, taxes, restrictions and trade statistics.
Countries add further digits for national detail — India, for example, uses an eight-digit ITC-HS classification. Using the correct HS Code is critical: a wrong code can lead to overpaid duty, clearance delays or penalties.
Buyers and suppliers should confirm the HS Code early, as it affects landed cost and eligibility for trade agreements.
