Last updated: August 2026 dataNylon and non-aramid polyamide filament tow serves as a key intermediate in the production of staple fibers, nonwovens, and engineered textiles for automotive, apparel, and industrial filtration markets. China is the dominant supplier to the US under this heading, with France and Taiwan also contributing meaningfully. The single tariff line 5501190000 captures all non-aramid polyamide tow not elsewhere specified, so correct fiber-type documentation is essential to avoid misclassification with the aramid subheading.

A manufacturer's fiber specification sheet or mill certificate identifying the polymer type (e.g., nylon 6 or nylon 6,6 versus para- or meta-aramid) is the most reliable supporting document. CBP may request this to confirm correct classification under 5501190000 versus the aramid subheading 5501110000.
Automotive airbag fabric, industrial filtration media, and cut-resistant workwear are among the primary downstream applications. Demand from these sectors can create seasonal or model-year-driven import surges that affect lead times and pricing.
