Analysis
Subheading 6203.31 covers of wool or fine animal hair, within heading 6203. 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 17.5% to 17.5% with a median of 17.5%, so the line you choose sets the duty.
The US splits it as follows: 6203.31.50 for of worsted wool fabric, made of wool yarn having an average fiber… (17.5%) and 6203.31.90 for of wool or fine animal hair: other (17.5%).
By Census's concordance, most of its statistical lines are made by Cut and Sew Apparel Manufacturing (3152). Those are the NAICS industries a US producer of these goods would report under.
Goods only reach 6203.31 once they fall within heading 6203 (men's or boys' suits, ensembles, suit-type jackets, blazers, trousers, bib and brace…). 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.
