Last updated: September 2026 dataAcrylic and modacrylic staple fiber yarns at 85% or more by weight, spun as single (non-plied) yarn and sold in bulk rather than retail packages, are a workhorse input for knitted outerwear, blankets, and upholstery fabrics. The single US tariff line under this heading is 5509310000. Guatemala leads US import supply, followed by Canada and Turkey — a geographically diverse sourcing base that reflects the global spread of acrylic spinning capacity. Importers should verify fiber content documentation carefully, as the 85% threshold is the classification boundary separating this heading from blended-fiber subheadings.

Classification at 85% or more acrylic or modacrylic by weight is based on the fiber composition of the yarn as imported. If the acrylic/modacrylic content falls below 85%, the yarn shifts to a blended-fiber subheading (e.g., 5509610000 or 5509620000 depending on the secondary fiber). Importers should obtain mill certificates or fiber analysis reports to substantiate the declared composition.
A single yarn is a strand produced in one spinning operation without subsequent twisting together with another strand. Multiple or cabled yarn (classified under 550932) consists of two or more single yarns twisted together. The distinction affects both the HTS line and, in some cases, applicable duty treatment, so the yarn's construction should be confirmed with the manufacturer before filing entry.
