2811

Analysis

Heading 2811 of the Harmonized Tariff Schedule covers other inorganic acids and other inorganic oxygen compounds of nonmetals. It divides into 6 six-digit subheadings and 12 eight-digit tariff lines, with 13 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 4.2%. The median line pays 3%.

The largest subheadings are 2811.29 (other, 4 lines), 2811.19 (other, 3 lines), 2811.22 (silicon dioxide, 2 lines) and 2811.11 (unnamed, 1 line).

By Census's concordance, most of its statistical lines are made by Other Basic Inorganic Chemical Manufacturing (325180) and Industrial Gas Manufacturing (325120). Those are the NAICS industries a US producer of these goods would report under.

Its median rate of 3% sits at the 46th 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.
