Abrasives and Grinding Wheels: Statutory & Effective Tariff Rates
USITC Column 1 General rates for 11 abrasives and grinding wheels HTS lines (parseable range 0% (+1 see schedule)). Effective rate Jun 2026: 9.55%; monthly history s
The short answer
- The observed effective calculated-duty rate on U.S. imports of abrasives and grinding wheels was 9.55% in Jun 2026, down from 10.76% a year earlier — USITC Calculated Duties divided by covered customs value. The Column 1 General line-rate range is 0% (+1 see schedule) across 11 HTS lines in the 2026 schedule; individual lines are called “Free” only when the official General field is literally Free, which still does not determine a shipment’s final duty. Mexico is the largest source, holding 13.6% of 2025 imports.
Statutory rates from the schedule
- Grinding wheels, honing stones, and coated abrasives — sandpaper, belts, and flap discs for every deburring and finishing pass. This family covers HTS headings 6804, 6805: 11 eight-digit rate lines with a parseable Column 1 General range of 0% (+1 see schedule) in the 2026 schedule. “Free” means the official General field is literally Free for that line; it does not determine final entry liability.
- 1 line carries compound or specific duties that cannot be stated as a single percentage; this page flags them "see schedule" rather than approximating.
- Chapter 99 references on individual lines (for example, 9903.90.08) identify provisions to review; applicability and any additional duty depend on the entry facts.
