Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If functions as a rectifier or power supply rather than pure transformer
Static converters including rectifiers fall under 8504.40 when they include rectification circuitry beyond simple voltage transformation
If power handling capacity is 40VA or greater but still under 1kVA
Higher VA ratings within the same voltage range shift to different statistical suffix for precise duty assessment
If imported as a component within a larger electrical apparatus assembly
Electrical machines with individual functions may be classified under 8543 when not imported as standalone transformers
