Analysis
Subheading 8483.50 covers flywheels and pulleys, including pulley blocks, within heading 8483. 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 2.8% to 5.7% with a median of 2.8%, so the line you choose sets the duty.
The US splits it as follows: 8483.50.40 for gray-iron awning or tackle pulleys, not over 6.4 cm in wheel diameter (5.7%), 8483.50.60 for other: flywheels (2.8%) and 8483.50.90 for other: other (2.8%).
By Census's concordance, most of its statistical lines are made by Mechanical Power Transmission Equipment Manufacturing (333613), Hardware Manufacturing (332510) and Motor Vehicle Gasoline Engine and Engine Parts Manufacturing (336310). Those are the NAICS industries a US producer of these goods would report under.
