U.S. imports of parts of turbojets and turbopropellers (HS 841191) totaled $1.5B in April 2026, traded with 64 countries.
Importers of Parts of Turbojets and Turbopropellers paid $17.4M in duties in April 2026 — an effective duty rate of 14% on $127.8M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataTurbojet and turbopropeller parts span a wide range of precision components — from cast-iron structural pieces to steel forgings and finished assemblies — each carrying distinct tariff treatment based on material, manufacturing method, and whether the part is destined for a civil aircraft engine. The US schedule separates cast-iron parts cleaned only (three lines by platform), non-aircraft parts (8411914000 and 8411919040), non-civil aircraft parts (8411917050), and aircraft engine parts by material — steel forgings (8411919081) versus all other civil aircraft engine parts (8411919085). France leads US imports under this heading, with Japan, Mexico, and Canada also significant sources, reflecting both OEM component manufacturing and MRO supply chains. Accurate classification requires knowing the base material, the manufacturing process (casting vs. forging vs. machined), and the intended engine platform.

The US schedule under 841191 explicitly separates cast-iron parts (cleaned only), steel forgings, and all other parts into distinct 10-digit lines. A steel forging for a civil aircraft turbojet engine falls to 8411919081, while a machined or otherwise processed steel part for the same engine falls to 8411919085. Misidentifying the manufacturing process is a common classification error that can result in incorrect duty assessment or CBP audit findings.
Each part must be classified individually based on its intended end-use platform. Civil aircraft engine parts and non-civil (military) aircraft engine parts fall to different tariff lines with potentially different duty rates and regulatory treatment. Importers should maintain part-level documentation — such as purchase orders, technical specifications, or airworthiness tags — that clearly identifies the intended platform for each line item in the entry.
