5604.90.90.00 - Other

This HTS category, 5604.90.90.00, encompasses "Other" rubber thread and cord, textile covered, and other textile yarns, strips, and the like of headings 5404 or 5405, which are impregnated, coated, covered, or sheathed with rubber or plastics. Essentially, it covers a broad range of textile-based materials combined with rubber or plastics that do not fit into more specific classifications within heading 5604. This includes items such as elastic threads and cords used in apparel and other textile articles, as well as strips of textile material that have been treated with rubber or plastics for enhanced properties.

This category is distinguished from its sibling, 5604.90.20.00, which specifically covers high tenacity yarns of polyesters, nylon, other polyamides, or viscose rayon that are also impregnated or coated. Therefore, 5604.90.90.00 applies to textile covered rubber threads and cords, as well as yarns and strips of *other* materials (not the specific ones listed in 5604.90.20.00) or those that are covered or sheathed with rubber or plastics, rather than solely impregnated or coated. The key differentiator lies in the material composition of the textile component and the specific method of rubber or plastic application.

As a leaf node, this classification represents the most specific level of detail for these goods. When classifying products under this heading, it is crucial to consider the primary textile material used, the nature of the rubber or plastic treatment (coating, covering, or sheathing), and whether the product is a thread, cord, or strip. If a product meets the general criteria of being a textile covered rubber thread or cord, or a treated textile yarn or strip, but does not meet the specific material or treatment requirements of other more narrowly defined subheadings, it will fall under this residual "Other" classification.
