Analysis
Subheading 7604.10 covers of aluminum, not alloyed, within heading 7604. 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 2.6% to 5% with a median of 3%, so the line you choose sets the duty.
The US splits it as follows: 7604.10.10 for of aluminum, not alloyed: profiles (5%), 7604.10.30 for having a round cross section (2.6%) and 7604.10.50 for bars and rods: other (3%).
By Census's concordance, most of its statistical lines are made by Other Aluminum Rolling, Drawing, and Extruding (331318). Those are the NAICS industries a US producer of these goods would report under.
Goods only reach 7604.10 once they fall within heading 7604 (aluminum 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.
