HS Codes Explained
HS codes (Harmonized System Code) are internationally standardized product classification codes. Understanding these codes is very useful when searching and analyzing trade statistics data.
What are HS Codes?
HS codes are based on the "Harmonized Commodity Description and Coding System" developed by the World Customs Organization (WCO). Adopted by approximately 200 countries, they serve as the standard for product classification in international trade.
