Harmonized System Tariff & HS Code Classification

Harmonized codes (or tariffs) are an international customs classification system now used by most trading nations throughout the world.

HS Codes are commonly used throughout the export process for goods. The Harmonized System is a standardized numerical method of classifying traded products. It is utilized by customs authorities around the globe to identify products when assessing duties and taxes and for gathering statistics. 

How to use HS Codes:

  • Classify physical goods for shipment to a foreign country;
  • Report shipments in the Automated Export System (AES) when the value is greater than $2,500, or the item requires a license.
  • Complete required shipping documentation such as shipper’s letter of instructions, commercial invoice or certificate of origin;
  • Determine import tariff (duty) rates and determine if a product qualifies for a preferential tariff under a free trade agreement;
  • Conduct market research and obtain trade statistics;
  • Comply with U.S. law, if needed.
