Among the industry classification systems, Harmony System Codes (HSC) are often used for goods throughout the export process. A harmony system is a standardized numerical method for classifying goods. It is used by customs authorities around the world to identify products and collect statistics when determining tariffs and taxes.

HS is managed by the World Customs Organization (WCO) and is updated every 5 years. It serves as the basis for the import /export classification system used in the United States and many trading partners. The HS issues specific six-digit codes for various classifications and products.

Countries may add a long code to the first 6 digits for further classification. The United States uses a 10-digit code to classify products for export. This is called the schedule B number and the first 6 digits are the HS number. All physical products, from paper clips to airplanes, have a Schedule B  number.

Many online platforms provide a free and widely available online Schedule B search tool that can be used to classify your products. The Schedule B search tool is the most widely used method for classifying products.

If you have difficulty classifying your products, the Customs Rulings Online Search System (CROSS) database can help you find your Schedule B code. CROSS contains official legally binding decisions by other exporters and importers seeking a Schedule B code. Use this database to determine if other exporters or importers have requested and if so, made decisions on the same or similar products. To find the HS code of the product in other countries, one can use the search tool in the foreign customs database.

It is critical that you get an accurate match of your product to the relevant HS code. Some importers try to game the system to avoid tariffs, particularly in bound to the US. We always recommend you do your own research as well as discuss this with your manufacturer as well as your customs agent. This will ensure you do not face an unexpected problem at the border along with penalties that may be charged or worse, a denial of entry.
