6006.31.00.20 - Of nylon (222)

This HTS category, 6006.31.00.20, specifically classifies knitted or crocheted fabrics of synthetic fibers that are unbleached or bleached and are constructed with a double knit or interlock stitch. The defining characteristic of this subheading is its explicit designation for fabrics composed of nylon. These fabrics are typically characterized by their dense, stable structure, often featuring a smooth face on both sides due to the intermeshing of stitches.

This classification is distinct from its sibling categories by the material composition. 6006.31.00.40 pertains to fabrics of polyester, while 6006.31.00.60 encompasses other synthetic fibers not specifically enumerated. Therefore, the primary differentiator for this subheading lies in the definitive identification of nylon as the sole synthetic fiber content for these unbleached or bleached double knit or interlock fabrics.

As this is a leaf node, there are no further subcategories within this specific classification. Classification decisions at this level are based on the confirmed presence of nylon, the unbleached or bleached state of the fabric, and its construction as a double knit or interlock. This ensures precise categorization for trade purposes, facilitating accurate tariff assessment and statistical tracking of nylon-based knitted or crocheted fabrics within this specific construction and processing state.
