Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If equipped with pile-driving or extracting mechanisms
Pile-drivers and extractors have separate provisions even if self-propelled.
If for electric self-propelled bulldozers used in tunneling prep
Bulldozers and angledozers classify under 8429 if primary function is earth moving.
If imported as a parts kit for vehicle-based tunneling rig
Parts for motor vehicles working off-highway may apply to chassis components.
