Last updated: August 2026 dataPolypropylene monofilament in this size range is a workhorse industrial input used in filtration media, agricultural netting, rope, and geotextiles. The US schedule subdivides the heading into three tariff lines — 5404120000, 5404121000, and 5404129000 — distinguishing by cross-sectional dimension and strip width, so precise physical measurement at entry is essential for correct classification. Canada leads US supply under this heading, benefiting from USMCA treatment, with Italy and Germany also significant sources. Importers sourcing from South Korea may also benefit from preferential treatment under KORUS.

Classification among 5404120000, 5404121000, and 5404129000 turns on two measurements: the cross-sectional dimension (whether it exceeds 1 mm) and, for strip-like forms, the width (whether it is 5 mm or less) and length. Importers should obtain certified dimensional specifications from the manufacturer before entry to avoid misclassification.
Polypropylene monofilament from China may be subject to Section 301 tariffs. No broad antidumping or countervailing duty orders are universally in place across all origins for this heading, but importers should check current CBP and USITC databases for any active orders or investigations before shipment, as trade-remedy coverage can change.
