Last updated: April 2026 dataPolypropylene single filament yarn with twist exceeding 50 turns per meter occupies a narrow but distinct classification niche, covering high-twist PP constructions used in specialty woven fabrics, fine filtration textiles, and certain technical applications. The heading consolidates into one 10-digit line (5402530000), covering all polypropylene filament yarns at this twist level that are not nylon or polyester. China is the leading US supplier, with Turkey and Greece also notable sources — a geographic spread that spans both large-volume Asian production and Mediterranean specialty textile manufacturing. Imports from China are subject to Section 301 tariffs, a cost factor that has encouraged some buyers to diversify toward Turkish or other origins.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Low-twist polypropylene yarn (≤50 turns/m) is predominantly used in bulk applications such as geotextiles, carpet backing, and rope. High-twist polypropylene yarn (>50 turns/m) is more commonly specified for fine woven fabrics, filtration media, and specialty technical textiles where the increased twist improves fabric cohesion and surface uniformity. The higher twist also affects dyeability and hand, though PP's inherent dyeing challenges remain regardless of twist level.
Yes — polypropylene filament yarn originating in China is subject to Section 301 tariffs, which increases landed cost relative to non-Chinese sources. Turkey and Greece are established alternative suppliers under this heading, and Vietnam and Mexico also appear in the broader polypropylene yarn supply base. Importers evaluating origin shifts should verify that alternative-origin yarn meets their technical specifications, since PP yarn properties can vary by resin grade and spinning technology.
