6006.42.00.25 - Of double knit or interlock construction (222)

This HTS category, 6006.42.00.25, specifically classifies knitted or crocheted fabrics of artificial fibers that are dyed and constructed using a double knit or interlock technique. Double knit fabrics feature two sets of needles creating a reversible fabric with a stable structure, while interlock is a type of double knit where the stitches on both sides are interlocking and aligned, resulting in a smooth and often thicker fabric. The crucial element for classification here is the specific construction method, indicative of a fabric with particular drape, elasticity, and surface characteristics.

This category is distinguished from its sibling, 6006.42.00.85, which covers "Other" knitted or crocheted fabrics of artificial fibers that are dyed. While both are dyed fabrics of artificial fibers, the distinction lies solely in the construction. 6006.42.00.25 applies only to those explicitly identified as double knit or interlock, whereas the sibling category encompasses all other dyed knitted or crocheted fabrics made from artificial fibers not meeting the double knit or interlock criteria.

As this is a leaf node in the HTS structure, there are no further subcategories to introduce. Classification under this heading is definitive once the material composition (artificial fibers), coloration (dyed), and specific construction (double knit or interlock) are established. For example, a dyed polyester interlock fabric used for activewear or sophisticated knit garments would fall under this classification.
