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.
Countries that use the HS are allowed to define commodities at a more detailed level than 6-digits, however all definitions must be within that 6-digit framework. The U.S., for example, defines products using 10-digit codes in its Harmonized Tariff Schedule (HTS).
Import codes are administered by the U.S. International Trade Commission (USITC).
Harmonized System (HS) and Schedule B numbers
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.
Schedule B Numbers are used to classify exported products in the United States and are based on the international HS system. HS numbers and Schedule B numbers will be the same up to the first 6 digits as the importing country's classification code.
Why 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. The Schedule B number is needed to complete the Shipper’s Export Declaration, Certificates of Origin and other shipping documents; and
3. The HS Number may be needed on shipping documents, such as certificates of origin
