Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

8504.40.40Same rate: 35%

If functions as rectifier unit

Primary rectification function classifies as static converter rather than pure transformer.

8504.90Lower: 10% vs 35%

If imported as inductor component

Pure inductors without transformation capability fall under separate parts category.

8504.23.00Higher: 36.6% vs 35%

If for capacities over 10 MVA

Very large power station transformers exceed distribution range subheadings.
