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

USITC Column 1 General rates for 44 turbines and fluid-power drives HTS lines (parseable range 0%–6.7%). Effective rate Jun 2026: 3.07%; monthly history since 2014.

The short answer

  • The observed effective calculated-duty rate on U.S. imports of turbines and fluid-power drives was 3.07% in Jun 2026, down from 6.49% a year earlier — USITC Calculated Duties divided by covered customs value. The Column 1 General line-rate range is 0%–6.7% across 44 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. 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 a parseable Column 1 General range of 0%–6.7% in the 2026 schedule. “Free” means the official General field is literally Free for that line; it does not determine final entry liability.

Observed calculated-duty data

  • Latest month on record (2026-06): 3.07% effective on $4.0B of imports, versus 6.49% in the same month a year earlier. The monthly archive holds 150 observations from 2014-01 through 2026-06.
  • In 2025, U.S. imports for consumption in this family totaled $40.8B in customs value, with $2.1B in USITC reported calculated duty on $40.8B of covered customs value: an effective calculated-duty rate of 5.22%. The aggregate reflects the recorded entry mix but does not attribute the result to a specific legal provision.
  • A year earlier the effective calculated-duty rate was 0.87%, so the observed rate rose 4.3 points.
  • Top source countries in 2025: Canada ($7.5B at 1.66%), France ($6.0B at 2.65%), United Kingdom ($4.5B at 1.67%), Mexico ($4.0B at 2.82%), Germany ($3.5B at 4.45%).
  • Reported freight and insurance equaled 1.35% of covered customs value in 2025 ($453.4M total); charge coverage was 82.2% of customs value, from USITC DataWeb. It is shown alongside the effective calculated-duty rate and is not part of the customs-value duty base.

Frequently asked questions

  • What is the U.S. tariff rate on turbines and fluid-power drives? USITC calculated duties imply an effective rate of 3.07% in Jun 2026 (calculated duties ÷ covered customs value, USITC DataWeb). The parseable Column 1 General line-rate range is 0%–6.7%; individual lines are called “Free” only when the official General field is literally Free, and product, origin, preference and tariff mix can contribute to the observed-rate difference.
  • What are the statutory MFN line rates for turbines and fluid-power drives? The parseable Column 1 General line-rate range is 0%–6.7% across the family's 44 eight-digit HTS lines in the 2026 Harmonized Tariff Schedule (headings 8406, 8410, 8411, 8412). “Free” means the official General field is literally Free for a line; it does not determine final entry liability.

About this data

  • Reference statistics derived from USITC published data. Not a customs ruling. MFN-Free and Special-rate fields describe statutory line coverage only; final entry liability requires origin, date, eligibility, exclusions and other transaction facts. Calculated Duties are statistical estimates, not a cash-collections ledger. Confirm classification, origin, program eligibility, and final entry liability with a licensed customs broker.
