6006.43.00.25 - Of double knit or interlock construction (222)

This classification, 6006.43.00.25, specifically covers knitted or crocheted fabrics of artificial fibers that are constructed using yarns of different colors. This implies fabrics where the visual effect of multiple colors is achieved through the use of pre-dyed yarns incorporated during the knitting or crocheting process, rather than through printing or dyeing the fabric after its construction. The "double knit or interlock construction" designation indicates a specific fabric structure characterized by interlocking loops, resulting in a fabric that is typically opaque, stable, and has the same appearance on both sides, often with a dense feel.

Distinguishing this category from its sibling, 6006.43.00.85 ("Other"), is crucial. While the sibling category would encompass knitted or crocheted fabrics of artificial fibers where the yarns are of the same color but the fabric construction results in a patterned or textured effect (e.g., jacquard, rib knit), or fabrics where the color is applied post-construction (e.g., dyed, printed), this subcategory is solely for those fabrics where the color variation originates from the different colored yarns used during knitting. The key differentiator is the method of achieving the multi-colored appearance.

As a leaf node, this category has no further subdivisions. Therefore, the classification hinges on the precise identification of the fabric as being made from artificial fibers, featuring a double knit or interlock construction, and importantly, being made of yarns of different colors. Examples include certain types of pique knits, double jersey, or other interlock constructions where contrasting colored yarns are strategically employed to create stripes, checks, or other multi-colored patterns directly within the fabric's structure.
