5603.14 - Weighing more than 150 g/m2:

This HTS category, 5603.14, encompasses nonwovens manufactured from man-made filaments that have a weight exceeding 150 grams per square meter (g/m²). These materials are characterized by their substantial weight and are typically formed by bonding or interlocking fibers through mechanical, chemical, or thermal processes. Products falling under this heading are generally robust and often used in applications requiring durability and structural integrity, such as filtration media, geotextiles, industrial wipes, or as components in the automotive and construction industries.

The critical distinction for this classification lies in its weight threshold. It is differentiated from its sibling categories, 5603.11, 5603.12, and 5603.13, by the definitive exclusion of nonwovens weighing 150 g/m² or less. Therefore, any nonwoven fabric composed of man-made filaments that surpasses this weight benchmark will be classified within 5603.14.

Within this broad category, further subdivisions exist to refine the classification. The subcategories are 5603.14.30, which specifically addresses laminated fabrics, and 5603.14.90, which serves as a residual category for all other nonwovens meeting the weight criteria but not being laminated. Laminated nonwovens, classified under 5603.14.30, involve the bonding of a nonwoven fabric to another material, such as a film or another textile, to enhance its properties or create a composite material with specific functionalities. The "Other" category is for nonwovens that are not laminated.
