5603.13.00.10 - Impregnated, coated or covered with material other than or in addition to rubber, plastics, wood pulp or glass fibers; "imitation suede" (223)

This HTS classification covers nonwoven fabrics primarily composed of man-made filaments that have a weight exceeding 70 grams per square meter but not exceeding 150 grams per square meter. These materials are distinguished by being impregnated, coated, or covered with substances other than, or in addition to, rubber, plastics, wood pulp, or glass fibers. A notable subset within this category includes materials specifically referred to as "imitation suede," which are manufactured to mimic the texture and appearance of natural suede.

Within the broader category of nonwovens weighing more than 70 g/m² but not more than 150 g/m², this specific subheading differentiates itself from other siblings based on its composition and treatment. For instance, HTS code 5603.13.00.70 would encompass nonwoven articles ready for use and packaged for industrial, institutional, or retail sale, suggesting finished goods rather than raw materials or semi-finished fabrics. The "Other" category (5603.13.00.95) serves as a residual for items not specifically described elsewhere at this level.

As this HTS code represents a leaf node, there are no further subdivisions. Classification into this specific subheading hinges on the fabric's weight falling within the specified range (71-150 g/m²), its nonwoven construction from man-made filaments, and the presence of impregnations, coatings, or coverings beyond those excluded by the primary description. The inclusion of "imitation suede" highlights a common and important application of these materials.
