Analysis
Subheading 9032.90 covers parts and accessories, within heading 9032. 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 3 US tariff lines below it are national.
None of its 3 lines is duty-free at the general rate. Rates run from 1.1% to 1.7% with a median of 1.7%, so the line you choose sets the duty.
The US splits it as follows: 9032.90.21 for designed for use in a 6, 12 or 24 V system (1.1%), 9032.90.41 for of automatic voltage and voltage-current regulators: other (1.7%) and 9032.90.61 for parts and accessories: other (1.7%).
By Census's concordance, most of its statistical lines are made by Automatic Environmental Control Manufacturing for Residential, Commercial, and Appliance Use (334512), Instruments and Related Products Manufacturing for Measuring, Displaying, and Controlling Industrial Process Variables (334513) and Motor Vehicle Electrical and Electronic Equipment Manufacturing (336320). Those are the NAICS industries a US producer of these goods would report under.
