6212.10.90.20 - Of man-made fibers (649)

This HTS category, 6212.10.90.20, specifically covers brassieres that are not knitted or crocheted and are manufactured from man-made fibers. This includes a wide range of brassieres constructed from synthetic materials like polyester, nylon, spandex, and rayon. The defining characteristic for this classification is the material composition, ensuring that garments made entirely or predominantly of these artificial fibers are correctly identified.

It is crucial to distinguish this category from its sibling, 6212.10.90.10, which exclusively classifies brassieres made of cotton. Therefore, any brassiere made from a blend containing significant amounts of man-made fibers would typically fall under this classification (6212.10.90.20) unless the cotton content is dominant and the specific cotton classification applies. The "Other" sibling category (6212.10.90.40) serves as a residual category for brassieres made from materials not otherwise specified within this group.

As this is a leaf node in the HTS structure, there are no further subcategories to explore under 6212.10.90.20. This means that the classification is finalized at this level based on the material (man-made fibers) and the product type (brassiere, not knitted or crocheted). Classification decisions at this point rely heavily on accurate declarations of the material content of the brassiere.
