5906.91.20.00 - Over 70 percent by weight of rubber or plastics

This HTS category, 5906.91.20.00, specifically covers knitted or crocheted textile fabrics that are not otherwise specified in heading 5902 and are over 70 percent by weight of rubber or plastics. These are essentially fabric-based materials that have been heavily treated or combined with rubber or plastic, resulting in a significant portion of their weight derived from these synthetic materials. The knitted or crocheted construction is a key defining characteristic, distinguishing them from woven or non-woven rubberized fabrics.

Within the "Knitted or crocheted" subcategory, this specific code differentiates itself from its sibling, 5906.91.25.00, which is designated for "Other" knitted or crocheted rubberized fabrics where the rubber or plastic content may be less than or equal to 70 percent by weight or where other distinguishing factors exist. Therefore, the primary differentiator for 5906.91.20.00 is the high proportion of rubber or plastic by weight.

As this is a leaf node, there are no further subcategories. Classification into this code depends on the verification that the fabric is indeed knitted or crocheted, that it is not covered by heading 5902, and crucially, that the rubber or plastic content constitutes more than 70 percent of its total weight. Examples could include certain types of industrial sheeting, specialized protective coverings, or heavy-duty rubberized fabrics used in applications where significant elasticity and water resistance are paramount.
