HS Code stands for Harmonized System Code, which is a standardized numerical method of classifying traded products. It is a global product classification system used by customs authorities around the world to identify products for assessing duties and taxes, among other things. 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. The United States uses a 10-digit code to classify products for export, known as a Schedule B number, with the first six digits being the HS number. The HS code is important for exports, and it is used to classify physical goods for shipment to a foreign country, report shipments in the Automated Export System (AES) when the value is more than $2,500, or the item requires a license, and complete required shipping documentation such as shipper’s letter of instructions, commercial invoice, or certificate of origin. To determine what the HS Code for a product is in another country, one can refer to the foreign country’s version of the HS code. The first six digits of the HS code are universally the same for all countries, but additional digits are added by different countries as per their national code systems.
