Last updated: September 2026 dataPolypropylene filament yarn at low twist is widely used in geotextiles, nonwovens, rope, carpet backing, and packaging applications, where its chemical resistance and low moisture absorption are commercially valued. The heading splits into two 10-digit lines — 5402480010 for general untwisted/low-twist constructions and 5402480070 for multifilament yarns with twist between 5 and 50 turns/m — allowing importers to match the correct line to their product's construction. South Korea leads US imports under this heading, with Turkey and India also significant suppliers. Polypropylene yarn from certain origins may be subject to Section 301 tariff considerations depending on country of origin.

Geotextile manufacturers, carpet backing producers, and industrial rope and cordage makers are among the primary consumers. The yarn's resistance to moisture, acids, and alkalis makes it preferred over polyester or nylon in certain civil engineering and agricultural applications. Packaging and nonwoven fabric producers also source this product for high-volume, cost-sensitive applications.
The 5402480010 line covers the broader category of polypropylene yarns that are untwisted or twisted up to 50 turns/m, while 5402480070 is specifically reserved for multifilament constructions with twist at or above 5 turns/m up to 50 turns/m. Importers should confirm filament count and twist measurement from the manufacturer to avoid misclassification between these two lines.
