Analysis
Subheading 8501.31 covers of an output not exceeding 750 W, within heading 8501. 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.
None of its 5 lines is duty-free at the general rate. Rates run from 2.4% to 4% with a median of 2.8%, so the line you choose sets the duty.
The US splits it as follows: 8501.31.20 for exceeding 37.5 W but not exceeding 74.6 W (2.8%), 8501.31.40 for exceeding 74.6 W but not exceeding 735 W (4%), 8501.31.50 for exceeding 735 W but under 746 W (3.3%), 8501.31.60 for motors: other (2.4%) and 8501.31.81 for of an output not exceeding 750 W: generators (2.5%).
By Census's concordance, most of its statistical lines are made by Motor and Generator Manufacturing (335312). Those are the NAICS industries a US producer of these goods would report under.
