5603.94.90.70 - Of filaments (223)

This HTS category, 5603.94.90.70, specifically classifies nonwoven textile materials that are neither made from filaments nor staple fibers, and weigh more than 150 grams per square meter. These "other" nonwovens are distinguished by their construction, falling outside the categories defined by the type of fiber used. The "Other" descriptor at this level indicates a further refinement within the broader category of nonwovens weighing over 150 g/m².

To classify goods under this heading, the primary determinant is that the nonwoven material is not primarily composed of continuous filaments or cut staple fibers. Instead, it may be constructed through other processes like spunbonding, meltblowing, or needle-punching, where the fiber arrangement and bonding create the nonwoven structure. It is crucial to distinguish these materials from those classified under sibling category 5603.94.90.90, which explicitly covers nonwovens of staple fibers.

As a leaf node, 5603.94.90.70 does not have further subcategories. Therefore, classification at this specific code relies entirely on meeting the criteria of being an "other" nonwoven, weighing more than 150 g/m², and not being of filaments or staple fibers. Examples might include certain needle-punched felts or air-laid nonwovens with a specific fiber composition not covered by filament or staple fiber classifications.
