Statutory HTS duty rates for 29 aluminum semi-finished products tariff lines (MFN Free–6.5%), from USITC. Effective rate May 2026: 54.12%; monthly history since 2014

Statutory rates from the schedule

  • Aluminum bar, rod, wire, plate, sheet, foil, and tube — extrusions and rolled stock for machining and fabrication. This family covers HTS headings 7604, 7605, 7606, 7607, 7608: 29 eight-digit rate lines with MFN (column 1, general) rates of Free–6.5% in the 2026 schedule.
  • Chapter 99 flags on individual lines mark Section 301/232 overlay provisions (e.g. 9903.91.01) that apply on top of the MFN column.

What importers actually paid

  • Latest month on record (2026-05): 54.12% effective on $1.1B of imports, versus 25.97% 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 $7.6B in customs value and paid $2.5B in calculated duties: an effective tariff rate of 32.81%. 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 6.15%, so the duty burden rose 26.7 points.
