Code 8504 90 · Heading 8504

Parts for transformers, static converters and induction coils, not specified elsewhere

This code covers parts for transformers, static converters and induction coils that are not covered by a more specific parts category. The deciding distinction is what type of equipment the part is for and, for transformer or induction-coil parts, whether it is a ferrite core, a steel lamination or core, or another part.

For example

  • A ferrite core for a transformer or induction coil
  • Steel laminations for a transformer or induction coil
  • Another part for a transformer or induction coil, not a ferrite core or steel lamination or core
  • A part for a static converter
