Analysis
Subheading 5408.22 covers dyed, within heading 5408. 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 14.9% to 14.9% with a median of 14.9%, so the line you choose sets the duty.
The US splits it as follows: 5408.22.10 for of cuprammonium rayon (618) (14.9%) and 5408.22.90 for dyed: other (14.9%).
By Census's concordance, most of its statistical lines are made by Broadwoven Fabric Mills (313210). Those are the NAICS industries a US producer of these goods would report under.
Goods only reach 5408.22 once they fall within heading 5408 (woven fabrics of artificial filament yarn, including woven fabrics obtained from…). 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.
