Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If sold as universal power supply transformer without oven-specific design
General transformers for electrical apparatus classify separately from oven-dedicated parts.
If parts of other industrial electric ovens or furnaces
Non-microwave oven heating parts go to different 8514 subheading.
If imported as electrical machinery part for unspecified appliances
Lack of microwave oven specificity leads to other electrical equipment parts.
