8411.12.40.00 - Aircraft turbines 🖩

This HTS category, 8411.12.40.00, specifically classifies aircraft turbojets with a thrust exceeding 25 kilonewtons (kN). These are sophisticated jet engines designed for the propulsion of aircraft, characterized by their powerful output. The "aircraft turbines" at the 8411.12 level are further narrowed down by the "turbojets" designation, meaning they operate by expelling a jet of gas at high speed. The critical distinguishing factor for this sub-heading is the measured thrust capability, specifically requiring a thrust rating greater than 25 kN to qualify.

This category is distinguished from its sibling, 8411.12.80.00, which covers "Other" aircraft turbojets. While both fall under aircraft turbojets with a thrust exceeding 25 kN, this specific sub-heading 8411.12.40.00 implies a more precise or distinct set of criteria within that thrust range that warrants separate classification, often relating to specific types or common configurations of high-thrust aircraft engines. Without further subcategories, the focus remains on the precise identification of these powerful aircraft propulsion systems based on their rated thrust.
