U.S. imports of Plastic Monofilament, Rods, Sticks & Profile Shapes, N.E.S. (Cross-Section > 1 mm) (SITC 58390) totaled $26.2M in August 2026, imported from 58 countries.
Importers of Plastic Monofilament, Rods, Sticks & Profile Shapes, N.E.S. (Cross-Section > 1 mm) paid $4.3M in duties in August 2026, an average duty rate of 16.33% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataResidual coverage for monofilaments exceeding 1 mm in cross-section and extruded profile shapes made from plastics not captured by the ethylene or vinyl chloride polymer headings — including nylon, polypropylene, acrylic, and engineering resins — falls here. These semi-finished forms are critical inputs for automotive trim, medical device housings, and specialty industrial components, where resin selection is driven by mechanical or thermal performance requirements. Because this is an NES heading, importers must first confirm that no named-polymer heading applies before using this classification.

Nylon (polyamide), polypropylene, acrylic (PMMA), polycarbonate, and various engineering thermoplastics frequently fall here when they do not match a named-polymer heading. The key step is confirming the resin identity through a material safety data sheet or resin certificate before determining that the NES heading is appropriate.
Applying a UV-stabilizing coating or incorporating color pigment during extrusion is generally considered surface-working or a production characteristic that does not remove the article from this heading. However, post-extrusion operations that significantly alter the shape — such as bending into a finished component or machining to close tolerances — may push the article into a finished-goods heading, so the extent of downstream processing should be evaluated carefully.
