Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If integrated with testing apparatus
Semiconductor testing equipment classifies in Chapter 90, not transmission components.
If molded resin injection molds for semiconductor parts
Special statistical notes cover certain semiconductor manufacturing molds separately.
If when identified as tool for wafer preparation
Wafer grinding machines themselves classify differently from speed components.
