5211.31.00.25 - Osnaburg (313)

This HTS classification covers Osnaburg fabrics that are woven from cotton but contain less than 85% cotton by weight, with the primary admixture being man-made fibers. These fabrics exceed a weight of 200 grams per square meter, classifying them as heavier cotton woven goods. The fabric must be dyed and woven in a plain weave structure. Specifically, this category applies to sheeting fabrics within the Osnaburg type that are not napped.

The key differentiator for this specific classification, 5211.31.00.25, lies in its "Sheeting" sub-designation combined with the "Not napped" descriptor. While other sibling categories at this level might also be dyed, plain weave, and weigh over 200 g/m², this entry precisely targets sheeting constructions that have not undergone a napping process. This distinguishes it from potentially similar fabrics that might be brushed or have a raised surface.

As this node represents a leaf node within the HTS structure, there are no further subcategories branching from this classification. Therefore, classification decisions at this point rely entirely on meeting all the preceding criteria: woven cotton content below 85% (mixed mainly with man-made fibers), weight exceeding 200 g/m², dyed status, plain weave construction, and application as sheeting without being napped.
