U.S. imports of Narrow Knitted or Crocheted Artificial Fiber Fabrics (Width ≤30 cm) (HS 600340) totaled $4K in September 2026, imported from 12 countries.
Narrow Knitted or Crocheted Artificial Fiber Fabrics (Width ≤30 cm) imports of $4K in September 2026 ran 92% below the year-to-date monthly average of $46K.
Last updated: September 2026 dataArtificial fiber narrow knits — viscose, modal, lyocell, and cupro trims and tapes not exceeding 30 cm wide — occupy a small but distinct classification niche outside headings 6001 and 6002. Australia and Canada lead US imports under this heading, an unusual supplier profile that reflects specialty industrial and medical-textile applications rather than mass apparel production. The heading divides into open-work (6003401000) and other knitted constructions (6003406000). Artificial fibers are cellulose-derived regenerated fibers and must be distinguished from synthetic (petroleum-derived) fibers; fiber-content declarations should specify the generic fiber name (e.g., viscose rayon, lyocell) to support correct classification.

Artificial fibers are regenerated cellulose-based fibers such as viscose rayon, modal, lyocell, and cupro, derived from natural cellulose sources. Synthetic fibers are petroleum-derived polymers such as polyester, nylon, and acrylic. This distinction determines whether a narrow knit fabric is classified under 600340 (artificial) or 600330 (synthetic), and fiber-content documentation must use the correct generic fiber name.
Classification follows the predominant fiber by weight. If artificial fibers (e.g., viscose) constitute more than 50% of total fiber content, the fabric falls under 600340; if synthetic fibers predominate, it falls under 600330. For blends where no single fiber class predominates, the chapter notes and General Rules of Interpretation guide the classification, and consultation with a licensed customs broker is advisable.
