Artificial staple fibers — primarily viscose rayon, modal, lyocell, and cupro — processed through carding or combing for spinning are a key input for soft-hand apparel yarns and blended fabrics. Unlike synthetic fibers derived from petrochemicals, artificial fibers are cellulose-based, a distinction that matters both commercially and for classification purposes. All US imports enter under the single tariff line 5507000000, and the heading covers all artificial fiber types without further subdivision at the 10-digit level.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Artificial fibers (heading 5507) are derived from natural cellulose — including viscose rayon, modal, lyocell, and cupro — while synthetic fibers (headings 5506 and related) are polymer-based and derived from petrochemicals. The distinction is chemical in origin: if the fiber's base material is regenerated cellulose, it is artificial; if it is a synthesized polymer, it is synthetic. This difference determines which heading applies and can affect duty rates.
No — heading 5507 and its single US tariff line 5507000000 do not subdivide by fiber type. Modal, lyocell, cupro, and standard viscose rayon are all classified together when carded or combed for spinning. Importers relying on fiber-specific marketing claims (e.g., 'Tencel' or 'ECOVERO') should ensure that commercial documentation accurately reflects the fiber's cellulosic origin for classification and any applicable sustainability certifications.
