Analysis
Heading 3925 of the Harmonized Tariff Schedule covers builders' ware of plastics, not elsewhere specified or included. It divides into 4 six-digit subheadings and 5 eight-digit tariff lines, with 7 ten-digit statistical suffixes below them.
None of its 5 lines is duty-free at the general rate. Rates run from 3.3% to 6.3% with a median of 5.3%, so the line you choose sets the duty.
The largest subheadings are 3925.30 (shutters, blinds (including venetian blinds) and…, 2 lines), 3925.10 (unnamed, 1 line), 3925.20 (unnamed, 1 line) and 3925.90 (unnamed, 1 line).
By Census's concordance, most of its statistical lines are made by All Other Plastics Product Manufacturing (326199) and Blind and Shade Manufacturing (337920). Those are the NAICS industries a US producer of these goods would report under.
Its median rate of 5.3% sits at the 51st percentile of the headings in chapter 39.
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.
