6006.33.00 - Of yarns of different colors

This HTS category, 6006.33.00, encompasses knitted or crocheted fabrics of synthetic fibers where the yarns used in their construction are of different colors. The distinguishing characteristic is the presence of multiple colors within the yarn itself, creating a patterned or variegated effect inherently present in the fiber before or during the knitting/crocheting process. This contrasts with sibling categories such as 6006.31.00 (unbleached or bleached) and 6006.32.00 (dyed), where the color is achieved through later treatment of the fabric or yarn. Furthermore, it is distinct from 6006.34.00 (printed), which involves the application of colorants to the surface of a pre-formed fabric.

Within this category, further classification is based on construction and specific applications. Subcategories exist to delineate between different knitting constructions, such as double knit or interlock fabrics, and a residual "Other" category for fabrics not fitting these specific constructions. This detailed breakdown allows for precise identification and ensures that fabrics with varying technical specifications or manufacturing methods are appropriately categorized, facilitating accurate trade statistics and tariff application. The "Of yarns of different colors" designation remains the primary unifying factor across all sub-classifications within 6006.33.00.
