Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

8504.34.00.00Higher: 36.6% vs 35%

If transformer stators without generator function

Pure transformer windings classify under electrical transformers heading.

8503.00.90.00Same rate: 35%

If APU-specific generator stators

Auxiliary power unit generators may have separate classification.

7017.90.50.00Higher: 41.7% vs 35%

If glass laboratory equipment stators (misclassification risk)

Beware of lab equipment misclassification; prove aircraft power generation use.
