US tariff schedule changes
USITC publishes a new revision of the Harmonized Tariff Schedule whenever lines or rates change. We compare each revision with the one before it, line by line.
First comparison coming soon. We started archiving the schedule with Revision 21 (2026). The first line-by-line comparison will appear here when USITC publishes the next revision. Follow @hs-code.net on Bluesky to hear about it.
