About heading 8504

Heading 8504 covers electrical transformers, static converters (for example, rectifiers) and inductors; parts thereof. It splits into 4 six-digit subheadings and 9 US tariff lines, 6 of which are duty-free under the general rate.

Headings are the four-digit level of the Harmonized System — the layer that is identical across all 160-plus countries that use it. The six-digit subheading is also international; the last two digits of each code here are US-specific and do not carry across to another country's tariff.
