8703.40.00.20 - Having engines with not more than 4 cylinders

This HTS classification, 8703.40.00.20, specifically applies to hybrid vehicles that utilize both a spark-ignition internal combustion piston engine and an electric motor for propulsion, and are not capable of being externally charged. The defining characteristic of vehicles under this heading is the number of cylinders in their internal combustion engine. This particular subcategory covers those hybrid vehicles where the internal combustion engine is equipped with no more than four cylinders, and the engine's cylinder capacity falls between 1,500 cc and 3,000 cc. These vehicles are primarily designed for the transport of persons, aligning with the broader scope of heading 8703.

Vehicles classified under 8703.40.00.20 are distinct from their sibling categories based on engine cylinder count. Category 8703.40.00.30 covers similar hybrid vehicles but with engines having more than four but not exceeding six cylinders, while 8703.40.00.40 encompasses those with more than six cylinders. Therefore, the precise number of cylinders in the internal combustion engine is the critical factor for differentiating between these closely related classifications.

As this node represents a leaf category within the HTS, there are no further subdivisions. The classification concludes at this level, meaning that any new or used vehicle meeting the criteria of being a hybrid (spark-ignition internal combustion engine and electric motor for propulsion, not externally chargeable), with an engine displacement between 1,500 cc and 3,000 cc, and having an internal combustion engine with four or fewer cylinders, will be classified under 8703.40.00.20. Examples would include specific models of hybrid sedans, SUVs, or coupes that fit these precise specifications.
