FAQ: Schedule B and HS Numbers

What’s the difference between the Schedule B codes (for exports) and the Harmonized Tariff Schedule (HTS) codes (for imports)?

The international Harmonized System (HS) is administered by the World Customs Organization and serves as the foundation for the import and export classification systems used in the United States.

The United States (U.S.) import classification system, the Harmonized Tariff Schedule (HTS) administered by the U.S. International Trade Commission (USITC), and the U.S. export classification system, the Schedule B administered by the U.S. Census Bureau, Foreign Trade Division, both rely on the international HS codes for their 4- and 6-digit headings and subheadings.

A Schedule B number is a 10-digit code used in the U.S. to classify physical goods for export to another country. An HTS number is a 10-digit code used to classify physical goods imported into the U.S. from another country. There are more HTS numbers than Schedule B numbers, reflecting a greater amount of detail on products imported into the U.S. Though matched at the 6-digit HS level, Schedule B and HTS codes for products may not be the same up to the 10-digit level. When filing U.S. import or export records, it is important to use the correct classification system.

Why do you need to know your product’s Schedule B and HS numbers?

Exporters need to know their product’s Schedule B and HS numbers for the following reasons:

  1. To determine applicable import tariff rates and whether a product qualifies for a preferential tariff under a Free Trade Agreement;
  2. To file the Electronic Export Information in the Automated Export System (AES); and
  3. To complete shipping documents, such as certificates of origin.
