2910
Epoxides, epoxyalcohols, epoxyphenols and epoxyethers, with a three-membered ring, and their halogenated, sulfonated, nitrated or nitrosated derivatives
Analysis
Heading 2910 of the Harmonized Tariff Schedule covers epoxides, epoxyalcohols, epoxyphenols and epoxyethers, with a three-membered ring, and their halogenated, sulfonated, nitrated or nitrosated derivatives. It divides into 6 six-digit subheadings and 8 eight-digit tariff lines, with 8 ten-digit statistical suffixes below them.
None of its 8 lines is duty-free at the general rate. Rates run from 3.7% to 5.5% with a median of 4.8%, so the line you choose sets the duty.
The largest subheadings are 2910.90 (other, 3 lines), 2910.10 (unnamed, 1 line), 2910.20 (unnamed, 1 line) and 2910.30 (unnamed, 1 line).
By Census's concordance, most of its statistical lines are made by All Other Basic Organic Chemical Manufacturing (325199). Those are the NAICS industries a US producer of these goods would report under.
Its median rate of 4.8% sits at the 44th percentile of the headings in chapter 29.
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.
