U.S. imports of synthetic elastomeric monofilament (67 decitex or more, cross-section not exceeding 1 mm) (HS 540411) totaled $12K in April 2026, traded with 7 countries.
Last updated: April 2026 dataElastomeric monofilaments — think spandex-type single strands used in swimwear, hosiery, and medical compression textiles — are classified here when they meet the 67-decitex threshold and stay within the 1 mm cross-sectional limit. The entire heading collapses into a single US tariff line (5404110000), simplifying classification but placing all volume under one duty exposure. China is the dominant supplier, with Japan and Argentina also contributing meaningfully to US import flows. Importers should note that Section 301 measures apply to Chinese-origin goods in this category, making origin documentation a critical compliance step.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
A monofilament is classified as elastomeric when it is made from a polymer — such as segmented polyurethane (spandex/Lycra-type) — that can be stretched significantly and recovers its original length. If the fiber is synthetic but not elastomeric (e.g., nylon or polyester), it falls under 540419 instead. The elastomeric property must be inherent to the polymer, not a result of texturing or processing.
Yes. Elastomeric monofilament classified under 5404110000 and originating from China is subject to Section 301 tariffs. Importers should verify the current list and rate applicability with a licensed customs broker, as exclusions and modifications have changed over time.
