On March 8, 2019, U.S. Customs and Border Protection (CBP) announced a timeline for converting the Harmonized Tariff Schedule of the United States (HTSUS) units of quantity (UOQ) to align with the Trade Facilitation and Trade Enforcement Act (TFTEA).
CBP is working with the U.S. Census Bureau and the U.S. International Trade Commission to change UOQ with a statistical suffix of “X” to specific quantities. According to CBP, the first HTSUS update was on January 1, 2019 and has tentatively scheduled the next update for January 1, 2020. CBP directs any questions to firstname.lastname@example.org.
