5603.94.90 - Other

This HTS code, 5603.94.90, encompasses "other" nonwoven textile materials that weigh more than 150 grams per square meter. These materials are not made by weaving, knitting, or felting but rather by bonding fibers together through mechanical, chemical, or thermal processes. The scope here is broad, covering nonwovens that do not fall into more specific classifications within heading 5603, and are specifically defined by their weight threshold.

To differentiate this category from its sibling, 5603.94.30.00, it's crucial to note that this "other" classification applies to nonwovens that are *not* laminated fabrics. Laminated fabrics, by definition, involve the bonding of two or more layers of material, whereas the nonwovens classified here may be impregnated, coated, or covered, but their primary characteristic is their single nonwoven layer construction, distinct from a multi-layered laminate.

This "other" category then further breaks down into more specific subcategories. 5603.94.90.10 addresses nonwovens that are impregnated, coated, or covered with materials other than or in addition to rubber, plastics, wood pulp, or glass fibers, explicitly including "imitation suede." The subsequent subdivision, 5603.94.90.20 (implied by the blank entry), would then capture any remaining nonwovens weighing over 150 g/m² that do not meet the criteria of the impregnated/coated subcategory, effectively serving as a residual classification for this weight class.
