If cotton becomes the predominant fiber — exceeding the acrylic or modacrylic content — the yarn would no longer classify under Chapter 55 (man-made staple fibers) and would instead fall under Chapter 52 (cotton) as a cotton yarn with synthetic fiber content. The 'mixed mainly with cotton' language in 550962 presupposes that acrylic/modacrylic is still the dominant fiber. Fiber analysis documentation is essential when the blend ratio is close to parity.
Yes. Under the Textile Fiber Products Identification Act (TFPIA), administered by the FTC, textile products sold in the US must be labeled with the generic fiber names and percentages by weight in descending order. For acrylic-cotton blended yarn, the label must accurately reflect the actual fiber composition. Importers and distributors are responsible for ensuring compliance before the product enters US commerce.
