Statutory HTS duty rates for 50 copper semi-finished products tariff lines (MFN 1%–3%), from USITC. Effective rate May 2026: 40.87%; monthly history since 2014.
Statutory rates from the schedule
- Copper bar, profile, wire, plate, sheet, foil, and tube — busbar, harness, and heat-exchanger stock. This family covers HTS headings 7407, 7408, 7409, 7410, 7411: 50 eight-digit rate lines with MFN (column 1, general) rates of 1%–3% in the 2026 schedule.
- Chapter 99 flags on individual lines mark Section 301/232 overlay provisions (e.g. 9903.88.03) that apply on top of the MFN column.
What importers actually paid
- Latest month on record (2026-05): 40.87% effective on $339.3M of imports, versus 1.68% in the same month a year earlier. The monthly archive holds 149 observations from 2014-01 through 2026-05.
- In 2025, U.S. imports for consumption in this family totaled $5.4B in customs value and paid $580.4M in calculated duties: an effective tariff rate of 10.82%. The effective rate captures Section 301/232 overlays, exclusions, and special-program use that the statutory column cannot.
- A year earlier the effective rate was 0.99%, so the duty burden rose 9.8 points.
