International Logistics: Schedule B and HS Numbers

What is a Harmonized System (HS) classification number, the Schedule B number, and it there a difference between the two numbers?

The Harmonized System (HS) Classification is a 6-digit standardized numerical method of classifying traded products. HS numbers are used by customs authorities around the world to identify products for the application of duties and taxes. Additional digits are added to the HS number by some governments to further distinguish products in certain categories.

In the United States, numbers used to classify exported products are called “Schedule B” numbers. The U.S. Census Bureau administers the Schedule B system. Schedule B numbers, not HS numbers, must be provided on the Shippers’ Export Declaration (SED). The Census Bureau uses SEDs and Schedule B numbers to calculate U.S. export statistics.

There is a difference between the HS classification number and the Schedule B number. The HS number is an internationally accepted code. The basic HS code contains 6-digits, known as a subheading. The Schedule B is a 10-digit code built upon the first 6 digits of the HS code. Additionally, the Schedule B code is a U.S.-specific coding system used by the U.S. Government to monitor U.S. exports.

To find you HS or Schedule B number, go directly to the Census Bureau website at http://www.census.gov/scheduleb to classify your own product through a keyword search.
