On April 21, 2026, the U.S. International Trade Commission (USITC) published a notice in the Federal Register with recommended changes to the Harmonized Tariff Schedule (HTS). 

In June of 2025, the World Customs Organization (WCO) adopted certain recommendations into the Harmonized System (HS) which will enter into force on January 1, 2028. According to the notice, USITC has initiated an investigation to "prepare recommendations for such modifications to the HTS as it considers necessary or appropriate to conform the HTS with such amendments to the Harmonized System."

The notice invites government agencies and the public to submit comments on any proposed changes. Comments are due by May 18, 2026.
