Analysis
Heading 7102 of the Harmonized Tariff Schedule covers diamonds, whether or not worked, but not mounted or set. It divides into 5 six-digit subheadings and 7 eight-digit tariff lines, with 11 ten-digit statistical suffixes below them.
Every one of its 7 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.
Its median rate of duty-free sits at the 23rd percentile of the headings in chapter 71.
The largest subheadings are 7102.21 (unworked or simply sawn, cleaved or bruted, 3 lines), 7102.10 (unnamed, 1 line), 7102.29 (unnamed, 1 line) and 7102.31 (unnamed, 1 line).
By Census's concordance, most of its statistical lines are made by Jewelry and Silverware Manufacturing (339910). 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.
