2842

Analysis

Heading 2842 of the Harmonized Tariff Schedule covers other salts of inorganic acids or peroxoacids (including aluminosilicates whether or not chemically defined), other than azides. It divides into 2 six-digit subheadings and 3 eight-digit tariff lines, with 4 ten-digit statistical suffixes below them.

None of its 3 lines is duty-free at the general rate. Rates run from 3.1% to 3.7% with a median of 3.3%, so the line you choose sets the duty.

The largest subheadings are 2842.90 (other, 2 lines) and 2842.10 (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 3.3% sits at the 55th 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.
