SITCSection 7
U.S. imports of gas turbines & turbopropellers (SITC 71481) totaled $59.7M in April 2026, traded with 7 countries.
Importers of Gas Turbines & Turbopropellers paid $316K in duties in April 2026 — an effective duty rate of 10% on $3.2M in dutiable value, based on actual customs collections rather than the published tariff schedule. Gas Turbines & Turbopropellers imports of $59.7M in April 2026 ran 11% below the year-to-date monthly average of $67.1M.
Last updated: April 2026 dataTurbopropeller engines couple a gas-turbine core to a reduction gearbox and propeller shaft, making them the preferred powerplant for regional turboprop aircraft and military transports where fuel economy at moderate speeds outweighs the speed advantage of pure jets. SITC 71481 captures both the complete turboprop assembly and standalone industrial gas turbines used in power generation and mechanical drive applications. Importers should confirm whether a unit is certified under FAA Part 33 (aircraft engines) or falls under industrial standards, as the applicable documentation and duty treatment can differ.

Not necessarily. While both may fall within SITC 71481, the HTS subheading at the 10-digit level and applicable regulatory requirements differ based on end use. Aircraft-certified turbines require FAA airworthiness documentation, whereas industrial units are governed by commercial equipment standards. Consulting a licensed customs broker before entry is recommended to confirm the correct classification.
A turbopropeller transmits most of its thrust through a gearbox-driven propeller, while a turbofan generates thrust primarily through a large ducted fan. This mechanical distinction drives separate SITC headings: turbopropellers fall under 71481, while turbofans are generally classified with turbojets under 71441. Engineering drawings or OEM specifications are the most reliable basis for making this determination at entry.
