Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If general-purpose transformer not tied to regulators
Inductors and transformers without specific apparatus use go to Chapter 85.
If for oscilloscopes or general voltmeters
Measuring instruments parts classified under heading 9030, not regulators.
If imported as power supply cable assemblies
Insulated cables with voltage sensing fall under Chapter 85 wiring provisions.
