HTS/Schedule B Units of Quantity Required on ALL Tariff Numbers as of January 1, 2020

As mentioned in ShapTalk December 2018 issue, all remaining tariff numbers will have a specific unit of quantity (UOQ) assigned to them.

Under the Trade Facilitation and Enforcement Act of 2015 (TFTEA), also referred to as the New Drawback Law, changes will be made to all HTS and Schedule B numbers for all units of measure currently indicated with an “X”.

An “X” appearing in the column for units of quantity means that no quantity (other than gross weight) is to be reported. All tariff numbers with a quantity measure of “X” will be replaced with an actual unit of measure to be used by Customs and Border Protection (CBP) to facilitate drawback claims.

If the specified units of quantity do not appear on your commercial invoice, Shapiro will be asking for additional information in order to submit the correct units of quantity to the Automated Commercial Environment (ACE).
