FAQ
Common Questions
What is the current USITC HTS revision?
The current active revision is 2026HTSRev17, effective 2026-08-24. HTS revisions are published annually (January 1) and sometimes mid-year to reflect legislative changes, trade agreements, or tariff actions.
How often does the HTS schedule change?

Why does the HTS revision matter for my imports?
