No — HTS 550952 covers polyester blended mainly with wool OR fine animal hair, so cashmere, alpaca, angora, and similar fine-hair fibers are included in the same heading as standard wool blends. However, the specific animal fiber content may be relevant for other regulatory purposes, such as country-of-origin labeling under the Textile Fiber Products Identification Act, which requires disclosure of fiber type and percentage.
When fiber proportions are close, the importer should obtain a certified fiber analysis from the manufacturer. 'Mixed mainly' means the wool or fine animal hair is the predominant non-polyester fiber; if another fiber type (e.g., cotton or artificial fiber) actually exceeds the wool content, the yarn would be reclassified to a different blended subheading. For borderline cases, a CBP binding ruling provides the most reliable classification certainty.
