Analysis
Subheading 5604.90 covers other, within heading 5604. The first six digits are shared by every country that uses the Harmonized System, so this part of the code is the same in the US, UK and EU schedules; the 2 US tariff lines below it are national.
None of its 2 lines is duty-free at the general rate. Rates run from 5% to 8.8% with a median of 6.9%, so the line you choose sets the duty.
The US splits it as follows: 5604.90.20 for high tenacity yarn of polyesters, of nylon or other polyamides or of… (8.8%) and 5604.90.90 for other: other (5%).
By Census's concordance, most of its statistical lines are made by Rope, Cordage, Twine, Tire Cord, and Tire Fabric Mills (314994) and Narrow Fabric Mills and Schiffli Machine Embroidery (313220). Those are the NAICS industries a US producer of these goods would report under.
Goods only reach 5604.90 once they fall within heading 5604 (rubber thread and cord, textile covered; textile yarn, and strip and the like of heading…). Under General Rule 6, subheadings are then compared only with others at the same level, so a product is matched against its siblings, not against lines elsewhere in the chapter.
