Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If specifically designed as original engine part for motor vehicles
Auto-specific pulleys may fall under Chapter 87 as parts of engines for vehicles rather than general transmission components.
If classified as pulley blocks rather than single pulley
Assemblies with blocks or multiple sheaves use a different subheading within the same pulley category.
If as replacement part without grooves fully machined
Incomplete grooved parts are treated as general pulley parts, not finished grooved pulleys.
