8407.29.00.20 - Less than 746 W

This HTS category, 8407.29.00.20, specifically covers spark-ignition internal combustion piston engines designed for marine propulsion that are also inboard engines with an inboard drive, and importantly, have a power output of less than 746 Watts (approximately 1 horsepower). These engines are typically found in smaller watercraft, such as tenders, dinghies, or auxiliary engines for sailboats where compact size and lower power output are sufficient for operation. The classification hinges on both the engine type (spark-ignition internal combustion piston) and its intended application (marine propulsion, inboard drive) combined with a precise power threshold.

Distinguishing this category from its siblings is crucial for accurate classification. 8407.29.00.30 covers engines of a similar type and application but with a higher power output, ranging from 746 Watts up to 18.65 kilowatts. Further up the power scale, 8407.29.00.40 encompasses engines exceeding 18.65 kilowatts. Therefore, the primary differentiator for 8407.29.00.20 is its specific power rating, indicating it is intended for applications requiring less robust propulsion.

As this is a leaf node within the HTS structure, there are no further subcategories branching from this specific classification. Classification decisions at this level are final and depend entirely on meeting the criteria of spark-ignition, piston internal combustion, marine propulsion, inboard drive, and the power output being less than 746 Watts. Importers and exporters should confirm these precise specifications to ensure correct declaration.
