Analysis
Subheading 5007.10 covers fabrics of noil silk, within heading 5007. 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 0.8% to 3.9% with a median of 2.35%, so the line you choose sets the duty.
The US splits it as follows: 5007.10.30 for containing 85 percent or more by weight of silk or silk waste (0.8%) and 5007.10.60 for fabrics of noil silk: other (3.9%).
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 5007.10 once they fall within heading 5007 (woven fabrics of silk or of silk waste). 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.
