Analysis
Subheading 7409.90 covers of other copper alloys, within heading 7409. 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 1.7% to 3% with a median of 3%, so the line you choose sets the duty.
The US splits it as follows: 7409.90.10 for of a thickness of 5 mm or more (3%), 7409.90.50 for of a width of 500 mm or more (1.7%) and 7409.90.90 for of a width of less than 500 mm (3%).
By Census's concordance, most of its statistical lines are made by Copper Rolling, Drawing, Extruding, and Alloying (331420). Those are the NAICS industries a US producer of these goods would report under.
