5511.10.00.30 - Acrylic or modacrylic (200)

This HTS classification, 5511.10.00.30, specifically covers yarns of synthetic staple fibers, containing 85 percent or more by weight of such fibers, when put up for retail sale, and composed of acrylic or modacrylic fibers. The key defining characteristic here is the fiber content, focusing on acrylic and modacrylic as the primary synthetic staple fibers that constitute the vast majority of the yarn's weight. This ensures that yarns primarily made of other synthetic staple fibers, such as polyester or nylon, would be classified elsewhere.

Within the broader category of "Yarn (other than sewing thread) of man-made staple fibers, put up for retail sale: Of synthetic staple fibers, containing 85 percent or more by weight of such fibers," this particular code differentiates itself from its sibling, 5511.10.00.60, "Other." The distinction lies in the specific identification of acrylic or modacrylic as the constituent fiber. Category 5511.10.00.60 would therefore encompass yarns meeting the general criteria of synthetic staple fiber content and retail packaging, but composed of synthetic staple fibers other than acrylic or modacrylic.

As this is a leaf node, there are no further subcategories to explore. The classification concludes at this level, meaning that once a yarn is identified as being composed of acrylic or modacrylic synthetic staple fibers, meeting the 85% by weight threshold, and is put up for retail sale, it is definitively classified under 5511.10.00.30. This precise coding ensures accurate reporting for trade statistics and customs duties related to these specific types of acrylic and modacrylic yarns.
