6006.33.00.20 - Of nylon (222)

This HTS subcategory, 6006.33.00.20, specifically classifies knitted or crocheted fabrics that are made from nylon yarns and are of a double knit or interlock construction. These fabrics are characterized by their construction, which involves interlacing two sets of yarns simultaneously to create a fabric with a smooth face and a slightly textured back, or a fabric where both sides have the same appearance. The key defining factor for this classification is the presence of nylon as the primary synthetic fiber.

This classification distinguishes itself from its sibling categories by the specific material composition. While 6006.33.00.40 covers similar double knit or interlock construction fabrics made of polyester yarns, and 6006.33.00.60 serves as a residual category for other synthetic fibers within this construction type, 6006.33.00.20 is exclusively for nylon. The "of yarns of different colors" designation within the parent category means that these fabrics can be constructed using nylon yarns of varying colors, resulting in striped, patterned, or heathered effects, or a solid color achieved through the combination of different colored yarns.

As this is a leaf node within the HTS, there are no further subcategories for this specific classification. Therefore, the classification is finalized based on the criteria of being a knitted or crocheted fabric, of synthetic fibers, with yarns of different colors, of a double knit or interlock construction, and specifically made of nylon. Importers should ensure that the fabric's composition and construction align precisely with these requirements to ensure accurate customs declaration.
