Analysis
Heading 7320 of the Harmonized Tariff Schedule covers springs and leaves for springs, of iron or steel. It divides into 3 six-digit subheadings and 7 eight-digit tariff lines, with 14 ten-digit statistical suffixes below them.
1 of its 7 lines with a percentage rate are duty-free at the general rate (14%) and 6 are dutiable, from duty-free up to 3.9%. The median line pays 3.2%.
Its median rate of 3.2% sits at the 83rd percentile of the headings in chapter 73.
The largest subheadings are 7320.10 (leaf springs and leaves therefor, 3 lines), 7320.20 (helical springs, 2 lines) and 7320.90 (other, 2 lines).
By Census's concordance, most of its statistical lines are made by Spring Manufacturing (332613). 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.
