Understanding Harmonized System (HS) Codes

The Harmonised System (HS) is an internationally recognised classification system for categorising and identifying traded products. The World Customs Organization (WCO) developed and maintains it. The HS assigns unique codes to products based on their composition, characteristics, and intended use. These codes, known as tariff codes or HS codes, are standardised across countries and facilitate the smooth flow of goods in global trade.


The primary purpose of the Harmonised System is to provide a common language for customs authorities, traders, and statisticians to classify products uniformly. It enables countries to classify goods consistently for customs procedures, tariff calculations, trade data collection, and analysis. Having a harmonised classification system promotes transparency, simplifies customs processes, and ensures fair trade practises.
