Analysis
Subheading 7407.10 covers of refined copper, within heading 7407. 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% to 3% with a median of 3%, so the line you choose sets the duty.
The US splits it as follows: 7407.10.15 for profiles: hollow profiles (3%), 7407.10.30 for profiles: other (3%) and 7407.10.50 for of refined copper: bars and rods (1%).
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.
Goods only reach 7407.10 once they fall within heading 7407 (copper bars, rods and profiles). Under General Rule 6, subheadings are then compared only with others at the same level, so a product is matched against its siblings, not against lines elsewhere in the chapter.
