Schedule B and HTS (HS) Codes

The Harmonized System

Export codes, also known as Schedule B numbers, are administered by the U.S. Census Bureau.

All import and export codes used by the United States are based on the Harmonized System (HS). The HS assigns 6-digit codes for general categories. This 6-digit code is known as the Harmonized System number.

Harmonized System (HS) numbers are used to classify products for customs purposes. By international agreement, most countries recognize the same first 6 "harmonized" digits.

To get a duty rate, one needs to have the complete product number used by the importing country. Since this is sometimes difficult, companies can use the Schedule B number to approximate.
