Artificial staple fibers are man-made fibers derived from natural polymers, most commonly viscose rayon, modal, lyocell (Tencel), and cupro. These differ from synthetic staple fibers (polyester, nylon, acrylic), which are petroleum-derived. Correct identification of the fiber's polymer origin is essential, as artificial and synthetic fibers classify under entirely separate HS chapters.
A single yarn is produced from one strand of drafted and twisted fibers. Once two or more single yarns are twisted together, the result is a multiple (folded) yarn; further twisting of multiple yarns produces a cabled yarn. This distinction is determined by the spinning and twisting process documented in the manufacturer's technical specification sheet, and it separates 551011 (single) from 551012 (multiple/cabled).
