2530

Analysis

Heading 2530 of the Harmonized Tariff Schedule covers mineral substances not elsewhere specified or included. It divides into 3 six-digit subheadings and 6 eight-digit tariff lines, with 8 ten-digit statistical suffixes below them.

5 of its 6 lines with a percentage rate are duty-free at the general rate (83%) and 1 are dutiable, from duty-free up to 2.9%. The median line pays duty-free.

The largest subheadings are 2530.90 (other, 3 lines), 2530.20 (kieserite, epsom salts (natural magnesium…, 2 lines) and 2530.10 (unnamed, 1 line).

By Census's concordance, most of its statistical lines are made by Other Nonmetallic Mineral Mining and Quarrying (21239). Those are the NAICS industries a US producer of these goods would report under.

Its median rate of duty-free sits at the 46th percentile of the headings in chapter 25.

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.
