9902.13.40 - Woven fabrics of synthetic staple fibers, containing 85 percent or more by weight of polyvinyl alcohol staple fibers and up to 15 percent of polynosic rayon fibers (provided for in subheading 5512.99.00)

This HTS classification, 9902.13.40, pertains to a very specific type of woven fabric composed primarily of synthetic staple fibers. The defining characteristic of these fabrics is their composition: they must contain at least 85 percent by weight of polyvinyl alcohol (PVA) staple fibers. An additional, limited component of up to 15 percent of polynosic rayon fibers is permitted within this classification. Crucially, this provision is intended to capture fabrics that would otherwise fall under subheading 5512.99.00, indicating a temporary modification or special rule applied to these particular PVA-rich woven textiles.

As this is a leaf node within Chapter 99, it does not have further subdivisions. Its distinctiveness lies precisely in the stringent material composition requirements, differentiating it from the broader categories of woven synthetic staple fiber fabrics found elsewhere in the HTS. While other woven fabrics might be classified under chapter 55, this entry carves out a specific niche for PVA and polynosic rayon blends, likely due to trade agreements or temporary legislative measures that impose particular import conditions or quotas on these materials. Importers must verify the exact fiber content through laboratory analysis to ensure accurate classification.
