Articles that are made from synthetic or artificial monofilaments, strip, or cordage but do not fit the descriptions for rope, knotted netting, or specific woven fabric headings end up here. Examples include woven or plaited articles made from synthetic strip (such as polypropylene flat tape woven into bags or mats) that are not classifiable as fabrics or as finished textile articles under other headings.

Artificial fibers (such as viscose rayon or lyocell) are derived from natural cellulose, while synthetic fibers (such as nylon, polyester, or polypropylene) are petroleum-based. Both are covered here, but the distinction can affect the applicable duty rate and any trade-remedy exposure, since antidumping or Section 301 measures may apply to one fiber type but not the other depending on the specific order's scope language.
