5901.90 - Other:

This HTS category, 5901.90, encompasses textile fabrics that have been treated with gum or amylaceous substances, and are intended for specific industrial or craft applications, excluding those explicitly for book covers. This includes prepared painting canvases, which are textile fabrics treated to accept paint for artistic purposes, as well as buckram and similar stiffened textile fabrics specifically designed for use in hat foundations. The "Other" designation signifies items that do not fit the specific description of materials for book covers provided in the preceding sibling category.

Distinguishing 5901.90 from its sibling, 5901.10, is crucial. While both fall under the broader umbrella of treated textile fabrics, 5901.10 exclusively covers materials used as outer covers for books or similar items. In contrast, 5901.90 pertains to other applications such as prepared painting canvas and stiffened fabrics for millinery. Therefore, the intended end-use and specific preparation of the textile fabric are key differentiators at this level.

Within 5901.90, further subdivision is provided to differentiate based on fiber content. The subcategories, 5901.90.20.00 and 5901.90.40.00, address the material composition of these treated fabrics. This allows for more precise classification based on whether the fabric is predominantly composed of man-made fibers or falls into an "Other" category, which would typically include fabrics made of natural fibers like cotton or linen, or blends not primarily consisting of man-made fibers.
