8411.12 - Of a thrust exceeding 25 kN:

This HTS category, 8411.12, covers turbojets designed to produce a significant amount of thrust, specifically those with a thrust exceeding 25 kilonewtons (kN). These powerful jet engines are primarily utilized in larger aircraft, including commercial airliners and military jets, where substantial engine power is required for takeoff and sustained flight. The classification hinges on this measurable thrust output, distinguishing them from smaller jet engines.

Distinguishing this category from its sibling, 8411.11, is crucial for accurate classification. HTS code 8411.11 pertains to turbojets with a thrust not exceeding 25 kN. Therefore, the sole criterion for differentiation at this level is the engine's thrust capacity, with 8411.12 exclusively encompassing those exceeding this 25 kN threshold.

Within 8411.12, further subdivisions exist to refine the classification of these high-thrust turbojets. The subcategory 8411.12.40.00 specifically addresses "Aircraft turbines," indicating a focus on engines directly integrated into aircraft propulsion systems. The residual category, 8411.12.80.00, covers "Other" turbojets that meet the thrust requirement but may not be exclusively designated for aircraft use, potentially including industrial applications or specialized propulsion systems.
