5603.94.90.50 - Obtained by mechanical entanglement, of staple fibers (223) 🖩

This HTS classification, 5603.94.90.50, specifically covers "Other" nonwovens, obtained by mechanical entanglement of staple fibers, weighing more than 150 g/m². These nonwoven fabrics are characterized by their construction where fibers are physically interlocked through processes such as needle-punching or hydro-entanglement, rather than being bonded by heat or chemicals. The "Other" designation at this level indicates that these mechanically entangled fabrics do not fall under any more specific sub-classifications within this broader category.

The key differentiator for this category lies in the manufacturing process. It stands apart from sibling categories that might cover similar staple fiber nonwovens but are produced through thermal bonding (e.g., 5603.94.90.30). The absence of thermal or chemical bonding is the primary criterion for classifying goods under 5603.94.90.50, provided they meet the weight and fiber type requirements.

As a leaf node in the HTS structure, this classification does not have further subcategories. Therefore, the focus for accurate classification under 5603.94.90.50 rests on confirming the mechanical entanglement method, the use of staple fibers, and the fabric weight exceeding 150 g/m². Examples of products fitting this description could include certain types of filtration media, industrial wipes, or padding materials where the structural integrity is achieved solely through mechanical fiber interlacing.
