The three subheadings split by fiber: nylon and other polyamide high-tenacity yarns go to 590210, polyester high-tenacity yarns to 590220, and viscose rayon to 590290. Importers must obtain fiber-content documentation from the manufacturer to declare the correct subheading, as duty rates can differ across the three.

No. Heading 5902 is specifically limited to tire cord fabric. High-tenacity woven fabrics used for belting, hose reinforcement, or other industrial applications classify under different headings in Chapter 59 depending on their construction and end use. The tire-specific application is a hard requirement of the heading text.
