High-tenacity nylon, polyamide, and polyester yarns are engineered for tensile strength well above standard textile grades, and woven fabrics made from them — classified under SITC 65311 — serve demanding end uses including ballistic panels, industrial webbing, parachute cloth, and heavy-duty luggage shell fabric. The 'other than pile or chenille and narrow or special fabrics' exclusion in the description is a meaningful scope boundary: pile constructions and narrow woven goods fall into separate headings regardless of yarn type. Section 301 tariffs have applied to certain synthetic woven fabrics of Chinese origin, making origin documentation and country-of-origin determination particularly important for this category.
