Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If used in non-semiconductor industrial compressors
General machinery parts not specific to semiconductor processes fall under broader tap/turbine parts headings.
If part of testing apparatus rather than processing equipment
Semiconductor testing machine parts are classified in Chapter 90 for measuring instruments.
If classified primarily as motor parts rather than compressor components
Parts recognized more specifically as motor stators go to Chapter 85 for electrical machinery.

Our AI classifier can analyze your specific product and recommend the correct HTS code with confidence.
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
