Analysis
Heading 2804 of the Harmonized Tariff Schedule covers hydrogen, rare gases and other nonmetals. It divides into 11 six-digit subheadings and 12 eight-digit tariff lines, with 16 ten-digit statistical suffixes below them.
5 of its 12 lines with a percentage rate are duty-free at the general rate (42%) and 7 are dutiable, from duty-free up to 5.5%. The median line pays 3.7%.
The spread of 5.5 percentage points between the cheapest and dearest lines makes misclassification expensive here. The highest rate, 5.5%, applies to 2804.69.50 (other: other).
The largest subheadings are 2804.69 (other, 2 lines), 2804.10 (unnamed, 1 line), 2804.21 (unnamed, 1 line) and 2804.29 (unnamed, 1 line).
Its median rate of 3.7% sits at the 67th percentile of the headings in chapter 28.
By Census's concordance, most of its statistical lines are made by Industrial Gas Manufacturing (325120), Nonferrous Metal (except Aluminum) Smelting and Refining (331410) and Other Basic Inorganic Chemical Manufacturing (325180). Those are the NAICS industries a US producer of these goods would report under.
