U.S. exports of monofilament, rods, sticks and profile shapes of plastics (nesoi) (HS 391690) totaled $32.0M in July 2026.
Importers of Monofilament, Rods, Sticks and Profile Shapes of Plastics (NESOI) paid $4.0M in duties in July 2026 — an effective duty rate of 20% on $19.8M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataThe residual plastics profile heading captures a commercially diverse range of semi-finished plastic shapes not made from ethylene or vinyl chloride polymers, including acrylic (PMMA) rods and profiles (3916901000), plastic racquet strings (3916902000), large-diameter monofilaments (3916903000 and 3916906000), and all other plastic rods and profile shapes (3916905000). Acrylic profiles serve display, signage, and optical applications, while plastic racquet strings represent a niche sporting goods line with its own dedicated tariff treatment. Canada and China are the leading suppliers across this heading, with Germany and Mexico also significant; Chinese-origin goods may carry Section 301 exposure depending on the specific line.

Racquet strings made of plastic monofilament with a cross-section exceeding 1 mm are classified in Chapter 39 as plastic profile shapes rather than in Chapter 56 or 95 as textile or sporting goods strings. The material composition (plastic rather than natural gut or textile fiber) and the cross-sectional dimension drive the Chapter 39 classification. Strings made of natural gut or textile fibers would classify differently, so material identification is essential.
To classify under 3916901000, acrylic (polymethyl methacrylate) rods and profiles must be 'not more than surface-worked' — meaning they have not been machined, shaped, or fabricated into a specific finished article. A product specification sheet confirming the material as PMMA, the cross-sectional dimensions, and a description of any surface treatment (cutting to length, polishing) helps establish that the goods remain semi-finished profile shapes rather than finished plastic articles subject to a different heading.
