Turbines and Fluid-Power Drives: Statutory & Effective Tariff Rates

Statutory HTS duty rates for 44 turbines and fluid-power drives tariff lines (MFN Free–6.7%), from USITC. Effective rate May 2026: 3.43%; monthly history since 2014.

The short answer

  • The effective U.S. tariff on turbines and fluid-power drives was 3.43% in May 2026, down from 7.37% a year earlier — calculated duties actually paid divided by customs value, from USITC data. The statutory MFN rate is Free–6.7% across 44 HTS lines in the 2026 schedule. Canada is the largest source, holding 18.4% of 2025 imports.

Statutory rates from the schedule

  • Steam, gas, and hydraulic turbines plus hydraulic and pneumatic motors — rotary power for generation and heavy motion. This family covers HTS headings 8406, 8410, 8411, 8412: 44 eight-digit rate lines with MFN (column 1, general) rates of Free–6.7% in the 2026 schedule.
  • Chapter 99 flags on individual lines mark Section 301/232 overlay provisions (e.g. 9903.88.01) that apply on top of the MFN column.
