Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If general-purpose semiconductor devices without generator mounting
Transistors not principally for 8501/8502 machines classify under semiconductor heading 8541.
If used in static converters rather than generator parts
Power modules primarily for separate converter equipment fall under 8504.
If with integrated monitoring circuits for test equipment
Hybrid modules with significant control functions may classify as automatic regulators.
