2506

Analysis

Heading 2506 of the Harmonized Tariff Schedule covers quartz (other than natural sands); quartzite, whether or not roughly trimmed or merely cut, by sawing or otherwise, into blocks or slabs of a rectangular (including square) shape. It divides into 2 six-digit subheadings and 2 eight-digit tariff lines, with 4 ten-digit statistical suffixes below them.

Every one of its 2 tariff lines is duty-free at the general rate, so classification within the heading affects statistics and Chapter 99 measures rather than the base duty.

The largest subheadings are 2506.10 (unnamed, 1 line) and 2506.20 (unnamed, 1 line).

By Census's concordance, most of its statistical lines are made by Dimension Stone Mining and Quarrying (212311). 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.
