Analysis
Heading 9109 of the Harmonized Tariff Schedule covers clock movements, complete and assembled. It divides into 2 six-digit subheadings and 11 eight-digit tariff lines, with 3 ten-digit statistical suffixes below them.
11 of the lines carry specific or compound rates (per kilogram, per dozen and so on) rather than a percentage, so their burden depends on the unit value of the goods.
The largest subheadings are 9109.10 (electrically operated, 8 lines) and 9109.90 (other, 3 lines).
By Census's concordance, most of its statistical lines are made by Other Measuring and Controlling Device Manufacturing (334519). 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.
