Analysis
Subheading 8504.40 covers static converters, within heading 8504. The first six digits are shared by every country that uses the Harmonized System, so this part of the code is the same in the US, UK and EU schedules; the 5 US tariff lines below it are national.
Every one of its 5 tariff lines is duty-free at the general rate, so classification within the subheading affects statistics and Chapter 99 measures rather than the base duty.
The US splits it as follows: 8504.40.40 for speed drive controllers for electric motors (duty-free), 8504.40.60 for suitable for physical incorporation into automatic data processing… (duty-free), 8504.40.70 for power supplies for automatic data processing machines or units… (duty-free), 8504.40.85 for for telecommunication apparatus (duty-free) and 8504.40.95 for static converters: other (duty-free).
By Census's concordance, most of its statistical lines are made by All Other Miscellaneous Electrical Equipment and Component Manufacturing (335999), Other Electronic Component Manufacturing (334419) and Relay and Industrial Control Manufacturing (335314). Those are the NAICS industries a US producer of these goods would report under.
