Alternative Classifications

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

8481.90.90Same rate: 35%

If used in non-semiconductor industrial compressors

General machinery parts not specific to semiconductor processes fall under broader tap/turbine parts headings.

9031.80.80Same rate: 35%

If part of testing apparatus rather than processing equipment

Semiconductor testing machine parts are classified in Chapter 90 for measuring instruments.

8503.00.95Higher: 38% vs 35%

If classified primarily as motor parts rather than compressor components

Parts recognized more specifically as motor stators go to Chapter 85 for electrical machinery.

Import Tips & Compliance

Verify the stator is designed exclusively for 8414.30 compressors used in semiconductor processes to avoid reclassification

Provide technical specs and end-use certification for semiconductor manufacturing to qualify for potential duty exemptions

Ensure documentation distinguishes from general industrial stators to prevent customs misclassification
