Analysis
Heading 2828 of the Harmonized Tariff Schedule covers hypochlorites; commercial calcium hypochlorite; chlorites; hypobromites. It divides into 2 six-digit subheadings and 2 eight-digit tariff lines, with 2 ten-digit statistical suffixes below them.
None of its 2 lines is duty-free at the general rate. Rates run from 2.4% to 3.7% with a median of 3.05%, so the line you choose sets the duty.
The largest subheadings are 2828.10 (unnamed, 1 line) and 2828.90 (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 3.05% sits at the 47th 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.
