what is an hs code

An HS code, or Harmonized System code, is a standardized numerical method of classifying traded products. It is used by customs authorities around the world to identify products when assessing duties and taxes. The HS assigns specific six-digit codes for varying classifications and commodities, and countries are allowed to add longer codes to the first six digits for further classification. In the United States, the Schedule B is a 10-digit code built upon the first 6 digits of the HS code, and it is used to classify products for export and monitor U.S. exports for export compliance and trade data collection
