The scope of this order covers large liquid dielectric power transformers (large power transformers) having a top power handling capacity greater than or equal to 60,000 kilovolt amperes (60 megavolt amperes), whether assembled or unassembled, complete or incomplete.
Incomplete large power transformers are subassemblies consisting of the active part and any other parts attached to, imported with or invoiced with the active parts of large power transformers. The "active part" of the transformer consists of one or more of the following when attached to or otherwise assembled with one another: the steel core or shell, the windings, electrical insulation between the windings, the mechanical frame for a large power transformer.
The product definition encompasses all such large power transformers regardless of name designation, including but not limited to step-up transformers, step-down transformers, autotransformers, interconnection transformers, voltage regulator transformers, rectifier transformers, and power rectifier transformers.
The large power transformers subject to this order are currently classifiable under subheadings 8504.23.0040, 8504.23.0080 and 8504.90.9540 of the Harmonized Tariff Schedule of the United States (HTSUS).
