Key Information on HS Codes: The Basics of the Harmonized System

HS codes, also known as Harmonized System codes, are an international standard for classifying goods used in international trade. The system was developed by the World Customs Organization (WCO) and is used by more than 200 countries and economic territories worldwide.

Every HS code is made up of six digits, which identify goods in a uniform, precise way. The first two digits identify the chapter the goods fall under, the next two indicate the heading within that chapter, and the last two digits identify the subheading. This system lets goods be classified consistently and clearly around the world.

HS codes are extremely important in international trade, because they allow goods to be uniquely identified, which is essential for setting duty tariffs, trade rules, and for statistical purposes and monitoring trade. They also make it easier for goods to move across borders, allowing for faster, more efficient customs clearance.

HS codes are regularly updated by the WCO to reflect changes in technology, trade patterns and regulatory needs. That's why it's important for exporters and importers to keep track of these changes, to ensure their goods are classified correctly.
