5509
Yarn (other than sewing thread) of synthetic staple fibers, not put up for retail sale
Analysis
Heading 5509 of the Harmonized Tariff Schedule covers yarn (other than sewing thread) of synthetic staple fibers, not put up for retail sale. It divides into 18 six-digit subheadings and 23 eight-digit tariff lines, with 27 ten-digit statistical suffixes below them.
The spread of 6.2 percentage points between the cheapest and dearest lines makes misclassification expensive here. The highest rate, 13.2%, applies to 5509.53.00 (mixed mainly or solely with cotton) and 5509.59.00 (other yarn, of polyester staple fibers: other…).
None of its 23 lines is duty-free at the general rate. Rates run from 7% to 13.2% with a median of 10.6%, so the line you choose sets the duty.
The largest subheadings are 5509.69 (other, 3 lines), 5509.99 (other, 3 lines), 5509.51 (mixed mainly or solely with artificial staple…, 2 lines) and 5509.11 (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.
