Analysis
Heading 2524 of the Harmonized Tariff Schedule covers asbestos. It divides into 2 six-digit subheadings and 2 eight-digit tariff lines, with 7 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 2524.10 (unnamed, 1 line) and 2524.90 (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.
