Analysis
Subheading 2804.69 covers other, within heading 2804. 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 2 US tariff lines below it are national.
None of its 2 lines is duty-free at the general rate. Rates run from 5.3% to 5.5% with a median of 5.4%, so the line you choose sets the duty.
The US splits it as follows: 2804.69.10 for containing by weight less than 99.99 percent but not less than 99… (5.3%) and 2804.69.50 for other: other (5.5%).
By Census's concordance, most of its statistical lines are made by Nonferrous Metal (except Aluminum) Smelting and Refining (331410). Those are the NAICS industries a US producer of these goods would report under.
Goods only reach 2804.69 once they fall within heading 2804 (hydrogen, rare gases and other nonmetals). 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.
