The U.S. Census Bureau regularly updates the Schedule B export classification codes in January and July. But this year and last, we also made changes to many Schedule B units of measure (UOMs) of X (no quantity required), assigning them specific quantities like kilograms to adhere to the Trade Facilitation and Trade Enforcement Act of 2015 (TFTEA)

U.S. Customs and Border Protection (CBP) needs specific UOMs for Harmonized Tariff Schedule (HTS) and Schedule B numbers to calculate duty drawback, a refund of duties, fees and taxes paid on goods imported into the U.S. and subsequently exported. (For more information on duty drawback, visit <>.) The U.S. International Trade Commission updated the UOMs of HTS numbers with duty rates at the beginning of 2019 – and assigned specific UOMs to the remaining numbers this January. For more information on these changes, see CBP’s website.

You can visit the List of Schedule B Codes Where Quantity Converted From X for 2020 and 2019 on our website. Also, check out our previous blog, New Schedule B Numbers Have Arrived, to learn about other resources. For background on the relationship between HTS and Schedule B numbers, see our blog, Exporting with Import Classification Numbers.
