5511

Analysis

Heading 5511 of the Harmonized Tariff Schedule covers yarn (other than sewing thread) of man-made staple fibers, put up for retail sale. It divides into 3 six-digit subheadings and 3 eight-digit tariff lines, with 4 ten-digit statistical suffixes below them.

None of its 3 lines is duty-free at the general rate. Rates run from 7.5% to 7.5% with a median of 7.5%, so the line you choose sets the duty.

Its median rate of 7.5% sits at the 23rd percentile of the headings in chapter 55.

The largest subheadings are 5511.10 (unnamed, 1 line), 5511.20 (unnamed, 1 line) and 5511.30 (unnamed, 1 line).

By Census's concordance, most of its statistical lines are made by Fiber, Yarn, and Thread Mills (313110). 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.
