U.S. imports of gas turbine parts, nesoi (other than for turbojets or turbopropellers) (HS 841199) totaled $493.3M in April 2026, traded with 58 countries.
Importers of Gas Turbine Parts, NESOI (Other Than for Turbojets or Turbopropellers) paid $18.8M in duties in April 2026 — an effective duty rate of 9.7% on $195.0M in dutiable value, based on actual customs collections rather than the published tariff schedule. Gas Turbine Parts, NESOI (Other Than for Turbojets or Turbopropellers) imports of $493.3M in April 2026 ran 12% above the year-to-date monthly average of $438.9M.
Last updated: April 2026 dataCovering parts for gas turbines other than turbojets and turbopropellers, this heading captures components for industrial power generation turbines, marine gas turbines, and non-turbojet/turboprop aircraft gas turbines. The US schedule distinguishes cast-iron parts (three lines by platform), non-aircraft parts (8411994000), non-civil aircraft parts (8411997050), and non-aircraft parts by type — rotors/spindles (8411999030), steel forgings (8411999081), and residual non-aircraft (8411999085) and aircraft (8411999090) lines. Mexico leads US imports, followed by Italy and Canada, a mix that reflects both industrial turbine component manufacturing and aerospace supply chains. The breadth of this heading means that a single turbine overhaul project may generate entries across multiple 10-digit lines.

The US schedule provides a dedicated line (8411999030) specifically for rotors, spindles, and their assemblies for non-aircraft gas turbines, separating them from the general non-aircraft parts lines. This specificity means that a rotor assembly must be classified to 8411999030 rather than the residual 8411999085 line, even if both lines would otherwise seem applicable.
An FAA Form 8130-3, EASA Form 1, or equivalent airworthiness release tag identifying the part as serviceable for a specific civil-certified engine type is the most direct evidence. For non-civil (military) aircraft parts, a military contract reference or end-use certificate may be required. Without platform-specific documentation, CBP may challenge the claimed tariff line during a CF-28 or CF-29 review.
