5512.21.00.90 - Other (220)

This HTS classification, 5512.21.00.90, encompasses woven fabrics primarily composed of synthetic staple fibers, with at least 85% by weight being synthetic staple fibers. Specifically, this category applies when the fabric contains 85% or more by weight of acrylic or modacrylic staple fibers, and it is either unbleached or bleached. The "Other (220)" designation indicates that this classification is for fabrics not specifically described by the preceding sibling categories within the "Unbleached or bleached" sub-heading.

This category serves as a residual for woven acrylic or modacrylic staple fiber fabrics that meet the primary composition thresholds but do not fall into more granular descriptions such as poplin, sheeting, printcloth, cheesecloth, lawns, voiles, batistes, or duck. The distinction from these sibling categories relies on the specific weave structure, yarn density, and intended end-use characteristics that define those more specific classifications. For instance, while all are woven synthetic staple fiber fabrics, this category captures those whose characteristics do not align with the defined properties of poplin (often a plain weave with fine yarns), sheeting (typically a plain weave with a specific thread count), printcloth (a plain weave fabric often finished for printing), or duck (a strong, plain weave fabric).

As a leaf node, this classification does not have further subcategories. Therefore, classification into 5512.21.00.90 hinges on the precise determination that the fabric meets the stipulated fiber content and bleaching status, and that its weave, texture, and other physical attributes do not correspond to any of the more specifically enumerated woven fabric types within the same heading.
