U.S. imports of synthetic monofilament, nesoi (67 decitex or more, cross-section not exceeding 1 mm) (HS 540419) totaled $4.3M in April 2026, traded with 24 countries.
Importers of Synthetic Monofilament, NESOI (67 Decitex or More, Cross-Section Not Exceeding 1 mm) paid $562K in duties in April 2026 — an effective duty rate of 18% on $3.2M in dutiable value, based on actual customs collections rather than the published tariff schedule. Synthetic Monofilament, NESOI (67 Decitex or More, Cross-Section Not Exceeding 1 mm) imports of $4.3M in April 2026 ran 11% below the year-to-date monthly average of $4.8M.
Last updated: April 2026 dataNylon, polyester, and other non-elastomeric, non-polypropylene synthetic monofilaments meeting the 67-decitex and 1 mm cross-section thresholds land here as the residual 'NESOI' category within heading 5404. The US schedule carves out a dedicated line for racket strings (5404191000) — a commercially distinct end-use — alongside separate lines for nylon/polyamide (5404198020), polyester (5404198040), and all other synthetic types (5404198080). Japan is the leading supplier, followed by Mexico and Germany, reflecting both precision manufacturing capability and proximity-driven supply chains. Correct polymer identification is critical because misidentifying nylon as polyester, or vice versa, shifts the applicable tariff line.

Racket strings (5404191000) are distinguished because they have a specific end-use and cross-sectional dimension range (1–5 mm) that sets them apart from general-purpose monofilament. This dedicated line allows CBP to apply a distinct duty rate and facilitates trade statistics for the sporting goods sector. Importers must confirm the product is actually intended and suitable for use as racket strings to claim this classification.
CBP expects a manufacturer's specification sheet or laboratory analysis confirming the polymer type (e.g., nylon 6, nylon 6,6, polyethylene terephthalate). For blended compositions, the predominant polymer by weight governs classification. A licensed customs broker can advise on whether a binding ruling from CBP is warranted for novel or ambiguous polymer blends.
