2829

Analysis

Heading 2829 of the Harmonized Tariff Schedule covers chlorates and perchlorates; bromates and perbromates; iodates and periodates. It divides into 3 six-digit subheadings and 6 eight-digit tariff lines, with 6 ten-digit statistical suffixes below them.

3 of its 6 lines with a percentage rate are duty-free at the general rate (50%) and 3 are dutiable, from duty-free up to 3.7%. The median line pays 1.55%.

The largest subheadings are 2829.90 (other, 4 lines), 2829.11 (unnamed, 1 line) and 2829.19 (unnamed, 1 line).

Its median rate of 1.55% sits at the 38th percentile of the headings in chapter 28.

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.

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.
