U.S. imports of woven fabrics of synthetic filament yarn, specifically bonded in layers (HS 540730) totaled $309K in April 2026, traded with 15 countries.
Last updated: April 2026 dataLayer-bonded synthetic filament fabrics — where two or more woven plies are laminated or adhesively bonded together as an integral structure — serve technical applications including automotive interlinings, composite reinforcement, and protective outerwear shells. The US schedule separates constructions by plastic content: fabrics where parallel textile yarns account for more than 60% by weight of plastic (5407301000) are distinguished from lighter plastic-content versions (5407309000). Italy leads US supply, consistent with its strength in technical and performance textile manufacturing, with Taiwan and India also significant. The bonding method and plastic-to-textile weight ratio are the controlling classification variables.

A laboratory analysis or manufacturer's technical data sheet stating the weight of plastic versus textile yarn per square meter is the standard supporting document. The 60% threshold refers to the weight of plastic relative to the total fabric weight. If the plastic content is borderline, an independent laboratory test per a recognized method (e.g., ASTM D629 for fiber content) provides the most defensible basis for classification.
CBP and the HS Explanatory Notes interpret 'specifically bonded' to mean the layers are intentionally joined as part of the manufacturing process to form a single fabric structure — not merely placed together. Whether the layers can be physically separated after bonding is less determinative than whether the bonding was integral to the product's design. Fabrics where layers separate easily under normal handling may be challenged as not meeting the 'specifically bonded' criterion.
