5512.99.00.10 - Blue denim (225)

This HTS category, 5512.99.00.10, specifically classifies woven fabrics of synthetic staple fibers that contain 85 percent or more by weight of synthetic staple fibers, with a focus on blue denim. The "blue denim (225)" designation indicates a specific type of woven fabric characterized by its indigo-dyed warp yarns and typically white filling yarns, creating the characteristic mottled blue appearance and durability. This classification applies when the fabric meets the weight threshold for synthetic staple fibers and is indeed blue denim.

Distinguishing this category from its sibling, 5512.99.00.05, is crucial. The sibling category covers "Other" woven synthetic staple fiber fabrics where the yarns are of different colors, excluding blue denim or fabrics with a jacquard weave. Therefore, if a woven fabric of synthetic staple fibers, meeting the 85% weight requirement, is blue denim, it falls under 5512.99.00.10, whereas other multi-colored woven synthetic staple fiber fabrics would be classified under the sibling.

As this node represents a leaf in the HTS structure, there are no further subcategories to introduce. Classification at this level is determined by the presence of blue denim within the defined parameters of woven fabrics containing 85 percent or more by weight of synthetic staple fibers, excluding other types of multi-colored weaves. Practical considerations for classification would involve verifying the fiber content and visually identifying the characteristic blue denim weave.
