Analysis
Heading 8458 of the Harmonized Tariff Schedule covers lathes (including turning centers) for removing metal. It divides into 4 six-digit subheadings and 6 eight-digit tariff lines, with 22 ten-digit statistical suffixes below them.
None of its 6 lines is duty-free at the general rate. Rates run from 4.2% to 4.4% with a median of 4.4%, so the line you choose sets the duty.
Its median rate of 4.4% sits at the 91st percentile of the headings in chapter 84.
The largest subheadings are 8458.91 (numerically controlled, 2 lines), 8458.99 (other, 2 lines), 8458.11 (unnamed, 1 line) and 8458.19 (unnamed, 1 line).
By Census's concordance, most of its statistical lines are made by Machine Tool Manufacturing (333517). 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.
