Silk yarn (other than yarn spun from silk waste) not put up for retail sale
Analysis
HTS 5004.00.00 covers silk yarn (other than yarn spun from silk waste) not put up for retail sale under heading 5004 (silk yarn (other than yarn spun from silk waste) not put up for retail sale).
Goods from countries without normal trade relations pay the column 2 rate of 40% instead of nothing, so origin decides between free entry and a 40% duty.
There is no general-rate duty on this line, which puts it with roughly 62% of the 13 tariff lines in chapter 50 that are also free. Chapter 99 measures such as Section 301 or 232 can still apply on top, depending on where the goods come from.
It is the only US line under subheading 5004.00, so the six-digit code used by every Harmonized System country and the eight-digit US line describe the same goods; a foreign tariff or an exporter's invoice showing 5004.00 points straight here.
Census statistics map these goods to NAICS 313110 (Fiber, Yarn, and Thread Mills), an industry of 250 US establishments employing 18,290 people, the industry a domestic producer of these goods reports under.
