Analysis
Heading 7201 of the Harmonized Tariff Schedule covers pig iron and spiegeleisen in pigs, blocks or other primary forms. It divides into 3 six-digit subheadings and 4 eight-digit tariff lines, with 4 ten-digit statistical suffixes below them.
Every one of its 4 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 7201.50 (alloy pig iron; spiegeleisen, 2 lines), 7201.10 (unnamed, 1 line) and 7201.20 (unnamed, 1 line).
By Census's concordance, most of its statistical lines are made by Iron and Steel Mills and Ferroalloy Manufacturing (331110). 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 72.
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.
