Importers of Parts of Reaction Engines, Linear-Acting Hydraulic & Pneumatic Motors, and NES Engines & Motors paid $30.1M in duties in July 2026 — an effective duty rate of 14% on $212.6M in dutiable value, based on actual customs collections rather than the published tariff schedule. Parts of Reaction Engines, Linear-Acting Hydraulic & Pneumatic Motors, and NES Engines & Motors imports of $341.0M in July 2026 ran 14% above the year-to-date monthly average of $299.5M.
Last updated: July 2026 dataCovering replacement and component parts for reaction engines (excluding turbojets), linear-acting hydraulic and pneumatic power units, and residual engine categories, SITC 71899 is a broad parts heading that demands careful classification to avoid misallocation with finished-goods headings. The essential character test — whether the part is dedicated to a specific engine type — drives correct assignment and affects duty treatment. Parts destined for MRO (maintenance, repair, and overhaul) programs may qualify for different entry procedures than parts imported for original equipment manufacturing.

When a part is designed or marketed for use with a specific engine type, it should follow that engine's parts heading. If the part is genuinely interchangeable across multiple engine categories, classification defaults to the residual parts heading (71899). Binding ruling requests to CBP can provide certainty for high-volume or high-value parts.
MRO parts may be eligible for special entry procedures such as duty drawback or bonded warehouse treatment, but they enter under the same tariff classification as OEM parts. The distinction matters for record-keeping and potential duty-recovery programs, not for the classification code itself.
