6004.90.90.00 - Other (222)

This HTS category, 6004.90.90.00, encompasses knitted or crocheted fabrics exceeding 30 cm in width that contain 5 percent or more of elastomeric yarn or rubber thread by weight, and which are not specifically classified under other headings within Chapter 60. These fabrics, therefore, are characterized by their elasticity and stretch, making them suitable for a wide range of apparel and industrial applications where flexibility is a key requirement.

This specific subheading differentiates itself from its sibling, 6004.90.20, by its composition. While 6004.90.20 specifically covers fabrics containing *both* elastomeric yarn and rubber thread, this subheading, 6004.90.90.00, is intended for fabrics containing at least 5% elastomeric yarn *or* rubber thread, but not necessarily both. This distinction is crucial for accurate classification, as the presence of one or both components dictates the correct tariff code.

As a leaf node, this category does not have further subdivisions. Therefore, the classification of goods under 6004.90.90.00 relies on the definitive criteria of containing 5% or more of elastomeric yarn or rubber thread by weight, while excluding fabrics that contain both as per the sibling category, and ensuring the fabric's width exceeds 30 cm. Examples of goods that might fall here include certain types of stretch knit fabrics used in activewear, swimwear, or some medical textiles where only one elastic component is present.
