Alternative Classifications

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

8504.22.00Lower: 35% vs 36.6%

If power capacity is 10,000-100,000 kVA

Lower power handling capacity shifts classification to the previous subheading within liquid dielectric transformers.

8504.33.00Same rate: 36.6%

If dry-type construction

Dry-type transformers without liquid dielectric fall under a different subheading regardless of power capacity.

8504.90Lower: 10% vs 36.6%

If imported as individual core or coil assemblies

Parts of transformers, not complete units, are classified separately under parts heading.
