5603.91.00.90 - Other (223)

This HTS classification, 5603.91.00.90, pertains to "other" nonwovens that weigh no more than 25 grams per square meter. These nonwoven fabrics are not specifically covered by other subheadings within 5603.91.00, which deals with nonwovens weighing not more than 25 g/m2. The key characteristic defining this category is its weight, making it suitable for lightweight applications.

This specific subheading distinguishes itself from its sibling, 5603.91.00.10, which covers nonwovens that are impregnated, coated, or covered with materials other than rubber, plastics, wood pulp, or glass fibers, or those described as "imitation suede." Therefore, 5603.91.00.90 applies to lightweight nonwovens that do not possess these additional treatments or characteristics.

As this is a leaf node, there are no further subcategories. Classification within this heading hinges on the absence of specific impregnations, coatings, or coverings, coupled with the weight not exceeding 25 g/m2. Examples of goods that might fall into this category include certain types of very lightweight disposable wipes, interlinings for apparel, or filtration media where the nonwoven fabric itself is the primary component and lacks significant additional treatments beyond its manufacturing process.
