Last updated: September 2026 dataArtificial fibers — including viscose rayon, modal, lyocell, and cupro — give knitted and crocheted fabrics in this heading a distinct drape, moisture absorption, and softness profile that differentiates them from synthetic-fiber counterparts. The US schedule covers double-knit/interlock constructions (6006410025) separately from other knit configurations (6006410085). China dominates US supply, with Taiwan and Mexico also among the leading sources. Correct classification requires distinguishing artificial (man-made cellulosic) fibers from synthetic (petroleum-derived) fibers, as the two fall under different HS headings and carry different duty treatment.

Artificial fibers are man-made from natural cellulosic sources — such as viscose rayon, modal, lyocell, and cupro — while synthetic fibers are derived from petrochemical polymers, such as polyester, nylon, and acrylic. This distinction is fundamental to HTS classification: artificial-fiber knit fabrics fall under heading 6006.4x, while synthetic-fiber knit fabrics fall under 6006.3x. Fiber content test reports from the manufacturer are the standard documentation used to support the correct classification.
Unbleached artificial-fiber knit fabrics retain their natural off-white or greige color and are typically destined for further processing — dyeing, printing, or finishing — before garment manufacturing. Bleached fabrics have been whitened and may be used as-is for white goods or as a base for lighter dye shades. The processing stage at time of import is relevant both to classification and to downstream supply chain planning.
