Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as bulk graphite material without customization
Unmachined graphite articles fall under Chapter 68 for non-specific industrial materials rather than semiconductor-specific parts.
If includes integrated temperature control sensors
Equipment with automatic control features may shift to Chapter 90 for semiconductor testing apparatus parts.
