5210.39.20.20 - Sateens (326)

This HTS category encompasses sateen fabrics woven from cotton, where cotton comprises less than 85% by weight and is mixed primarily or solely with man-made fibers. The fabric must also weigh no more than 200 g/m². Sateens are characterized by their distinctive smooth, lustrous surface, achieved through a weave structure where warp threads float over several weft threads, or vice versa, creating a smooth face with minimal interlacing. This weave is a key identifier for classification within this specific sub-category.

Distinguishing this category from its sibling, 5210.39.20.90 (Other), is the explicit requirement for a satin weave. The "Other" category would cover woven fabrics within the same material composition and weight parameters that do not utilize a satin weave. Therefore, the presence of the characteristic smooth, glossy surface and the underlying satin weave structure are crucial for accurate classification under 5210.39.20.20.

As this is a leaf node in the HTS, there are no further subdivisions. Classification under this code is final, provided all preceding criteria, including the material composition, weight, and weave structure, are met. Examples of goods that would fall here include certain types of apparel linings, decorative fabrics, or upholstery materials where the smooth, satiny finish is a primary characteristic and the fabric is constructed with a significant proportion of man-made fibers alongside cotton.
