Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the primary function is high-temperature zone refining rather than mechanical shaping
Induction heating furnaces for semiconductor processing may fall under industrial furnaces.
If dedicated solely to semiconductor crystal growth without metal removal
Statistical notes direct pure semiconductor manufacturing apparatus to Chapter 84 heading 8486.
