Last updated: April 2026 dataCarded, combed, or otherwise processed acrylic and modacrylic staple fibers are a key upstream input for the apparel, home textiles, and industrial nonwovens sectors, valued for their wool-like hand and dyeability. The distinction between acrylic and modacrylic matters at classification: modacrylic fibers contain a lower proportion of acrylonitrile and are often used in flame-retardant applications. Imports of processed acrylic staple fiber have faced antidumping scrutiny from multiple origins, making country-of-origin documentation a recurring compliance priority for yarn spinners sourcing globally.

The key criterion is acrylonitrile content: acrylic fibers contain 85% or more acrylonitrile by weight, while modacrylic fibers fall between 35% and 85%. Importers should confirm fiber composition from the manufacturer's technical data sheet before declaring the classification, as misclassification between the two can affect applicable duty rates and any trade-remedy exposure.
Certain origins of acrylic staple fiber have historically been subject to antidumping duty orders. Importers should check the current scope of any active orders with the US International Trade Commission and USDOC before shipment, as scope rulings can affect whether a specific fiber specification or country of origin falls within a covered order.
