Warp Knit Fabrics of Synthetic Fibers, Unbleached or Bleached

Stitch-bonded fabrics are produced by stitching together layers of fibers, yarns, or existing fabrics using warp-knit stitching — they are not formed by conventional interloping of yarns alone. This construction method, associated with products like Malimo-type fabrics, places them in a specific tariff line. Importers should obtain mill documentation describing the production process to support classification in 6005360020 versus the residual 6005360080 line.

A fabric is considered unbleached if it retains its natural off-white or gray color from the synthetic fiber without any whitening treatment. Bleached fabrics have undergone a chemical whitening process to achieve a brighter white. Both states are captured within the same subheading 600536, so the distinction affects statistical reporting and may affect quota or trade-remedy tracking but does not change the 6-digit heading. The specific 10-digit line used should reflect the actual finishing state as documented by the mill.
