Synthetic staple fibers, not carded, combed or otherwise processed for spinning
Analysis
Heading 5503 of the Harmonized Tariff Schedule covers synthetic staple fibers, not carded, combed or otherwise processed for spinning. It divides into 6 six-digit subheadings and 8 eight-digit tariff lines, with 11 ten-digit statistical suffixes below them.
2 of its 8 lines with a percentage rate are duty-free at the general rate (25%) and 6 are dutiable, from duty-free up to 4.3%. The median line pays 4.3%.
Its median rate of 4.3% sits at the 10th percentile of the headings in chapter 55.
The largest subheadings are 5503.19 (other, 2 lines), 5503.90 (other, 2 lines), 5503.11 (unnamed, 1 line) and 5503.20 (unnamed, 1 line).
By Census's concordance, most of its statistical lines are made by Artificial and Synthetic Fibers and Filaments Manufacturing (325220). 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.
