U.S. imports of Woven Fabrics of Other Synthetic Staple Fibers (Not Polyester, Acrylic, or Modacrylic), Under 85%, Mixed with Other Fibers (NESOI) (HS 551599) totaled $245K in September 2026, imported from 34 countries.
Importers of Woven Fabrics of Other Synthetic Staple Fibers (Not Polyester, Acrylic, or Modacrylic), Under 85%, Mixed with Other Fibers (NESOI) paid $44K in duties in September 2026, an average duty rate of 17.92% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Woven Fabrics of Other Synthetic Staple Fibers (Not Polyester, Acrylic, or Modacrylic), Under 85%, Mixed with Other Fibers (NESOI) imports of $245K in September 2026 ran 22% below the year-to-date monthly average of $313K.
Last updated: September 2026 dataResidual woven fabrics of non-polyester, non-acrylic, non-modacrylic synthetic staple fibers blended with fibers other than manmade filaments — including wool, fine animal hair, cotton, or other natural fibers — are captured here when synthetic staple content is under 85% by weight. Italy leads US imports, with India, China, Turkey, and France also supplying the market, reflecting a globally distributed production base for specialty synthetic blends. The US schedule is notably detailed, with wool/fine animal hair blend lines subdivided by the 36% wool weight threshold and combing status (lines 5515990510, 5515990520, 5515991010, 5515991020), plus separate lines for cotton and other fiber blends. Given the residual nature of this heading, importers should systematically rule out all more specific headings before classifying here.

The classification logic requires ruling out headings 551511–551519 (polyester staple blends) and 551521–551529 (acrylic/modacrylic staple blends) before arriving at 551599. If the synthetic staple fiber is confirmed as neither polyester nor acrylic/modacrylic, and the blending fiber is cotton (not a manmade filament), then 551599 applies. A fiber identification report specifying the polymer type is the key supporting document.
Lines 5515990510 and 5515990520 apply when wool or fine animal hair is 36% or more by weight (uncombed and combed, respectively), while lines 5515991010 and 5515991020 cover fabrics where wool or fine animal hair is below that threshold. When wool content is near the 36% boundary, a precise gravimetric fiber analysis is essential, and a binding ruling from CBP may be warranted to lock in the correct line before large-volume shipments.
