Last updated: September 2026 dataCoarse-count single combed cotton yarn — where short fibers have been removed before spinning — delivers greater uniformity and strength than its uncombed counterpart at the same metric number, making it preferred for heavy-duty woven goods requiring a cleaner surface. Pakistan and India are the leading suppliers to the US market, with China-origin shipments subject to Section 301 tariffs. The 10-digit lines under this subheading (5205210000, 5205210020, and 5205210090) distinguish ring-spun from other spinning methods, a specification detail that affects fabric performance and buyer acceptance.

Ring spinning produces a stronger, more uniform yarn with better surface characteristics than open-end or air-jet spinning at equivalent counts. The US schedule's 10-digit line 5205210020 specifically captures ring-spun product, reflecting commercial demand distinctions that matter to fabric mills — and potentially to duty treatment under certain trade programs or quota provisions.
Customs may request a mill certificate or fiber analysis confirming the combing process. Combed yarn typically shows a more parallel fiber arrangement, fewer neps, and a smoother surface under microscopic examination. Without documentation, CBP may require laboratory testing, which can delay entry — so obtaining combing-process certification from the spinner before shipment is advisable.
