5603.94.90.90 - Of staple fibers (223)

This HTS category, 5603.94.90.90, specifically classifies nonwoven textile materials made from staple fibers. These materials are characterized by being "other" within the broader classification of nonwovens weighing over 150 g/m², and also "other" in terms of their construction or treatment beyond the most specific categories. The defining feature is their composition of staple fibers, which are short, discrete lengths of textile material.

To distinguish this category from its sibling, 5603.94.90.70, it's crucial to note the material composition. While both fall under "other nonwovens weighing more than 150 g/m²," this classification specifically excludes nonwovens made from continuous filaments. Therefore, the key differentiator lies in whether the nonwoven is constructed from short staple fibers or long, unbroken filaments.

As this is a leaf node within the HTS, there are no further subcategories. Classification within 5603.94.90.90 is determined by the material being exclusively staple fibers, meeting the weight threshold of over 150 g/m², and not fitting into more specific classifications within Chapter 56 that might address particular treatments or forms of nonwovens. Examples might include certain types of heavy-duty nonwovens used in industrial applications, filtration media, or geotextiles primarily composed of staple fibers.
