Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If exceeding 22.38 kW
Higher power rotary stationary compressors/vacuum pumps move to the next power bracket subheading.
If primarily for testing semiconductor devices
Statistical notes place certain testing apparatus pumps in Chapter 90, separate from general processing compressors.
If imported as replacement part for existing semiconductor tool
Parts of air/vacuum pumps classify separately, not as complete units.

Import Tips & Compliance
• Provide vacuum level specs (e.g
• <10^-3 Torr) and semiconductor end-use affidavits for preferential treatment
• Label as 'dry rotary' if oil-free to distinguish from lubricated pumps; check for export control under EAR for vacuum tech
