8411.11.40.00 - Aircraft turbines

This HTS category, 8411.11.40.00, specifically covers turbojets designed for aircraft with a thrust not exceeding 25 kilonewtons (kN). These are jet engines whose primary function is to propel an aircraft by expelling a high-speed jet of gas. Examples include engines used in smaller trainer aircraft, unmanned aerial vehicles (UAVs), or as auxiliary power units in larger aircraft. The key defining characteristic for classification here is the maximum thrust output, which is capped at 25 kN.

Distinguishing this subcategory from its sibling, 8411.11.80.00, is crucial for accurate classification. While both fall under "Turbojets of a thrust not exceeding 25 kN," the 80.00 subcategory likely encompasses specific types or variations of turbojets within that thrust range not covered by the .40.00 designation, potentially based on specific technical features or intended applications not solely defined by thrust. In essence, 8411.11.40.00 is for a more precisely defined segment of low-thrust aircraft turbojets.

As this node is a leaf node within the HTS structure, there are no further subcategories. Classification decisions within this code will rely on adhering strictly to the definition of a turbojet for aircraft use and ensuring the stated thrust capacity does not exceed 25 kN. Importers and exporters must be able to provide documentation or specifications verifying this thrust limitation to correctly classify goods under this specific tariff line.
