Analysis
Heading 2806 of the Harmonized Tariff Schedule covers hydrogen chloride (Hydrochloric acid); chlorosulfuric acid. It divides into 2 six-digit subheadings and 2 eight-digit tariff lines, with 2 ten-digit statistical suffixes below them.
1 of its 2 lines with a percentage rate are duty-free at the general rate (50%) and 1 are dutiable, from duty-free up to 4.2%. The median line pays 2.1%.
The largest subheadings are 2806.10 (unnamed, 1 line) and 2806.20 (unnamed, 1 line).
By Census's concordance, most of its statistical lines are made by Other Basic Inorganic Chemical Manufacturing (325180). Those are the NAICS industries a US producer of these goods would report under.
Its median rate of 2.1% sits at the 41st percentile of the headings in chapter 28.
The heading text decides whether a product belongs here at all (General Rule of Interpretation 1); the subheadings and lines below it only apply once that is settled. Section and chapter notes can override the heading wording, so read them for borderline goods.
