8408.90.10.80 - Exceeding 37.3 kW

This HTS category, 8408.90.10.80, specifically covers compression-ignition internal combustion piston engines, commonly known as diesel or semi-diesel engines, that are intended for installation in agricultural or horticultural machinery or equipment and have a power output exceeding 37.3 kilowatts (kW). These engines are designed to operate on the diesel principle, igniting fuel through compression rather than a spark plug. The key defining characteristic for this subclassification is their substantial power output, indicating their use in larger, more demanding agricultural and horticultural applications.

The primary distinction of this category from its sibling, 8408.90.10.40, lies solely in their power rating. While both are compression-ignition engines intended for agricultural or horticultural machinery, this code applies to those exceeding 37.3 kW, whereas the sibling covers engines not exceeding this power threshold. This power differentiation is critical for customs classification as it often reflects the intended application and operational capacity of the engine within the machinery.

As a leaf node within the HTS structure, this category does not possess further subcategories. Therefore, the classification is finalized at this level based on the engine type (compression-ignition internal combustion piston engine), its intended use (for installation in agricultural or horticultural machinery or equipment), and its power output (exceeding 37.3 kW). Examples of machinery that might incorporate these engines include large tractors, combine harvesters, industrial tillers, or specialized landscape management equipment requiring significant power.
