6006.41.00.25 - Of double knit or interlock construction (222)

This HTS category, 6006.41.00.25, specifically classifies knitted or crocheted fabrics of artificial fibers that are unbleached or bleached and are of a double knit or interlock construction. Double knit fabrics are characterized by having two distinct sets of needles working simultaneously to produce a thicker, more stable fabric with the same appearance on both sides. Interlock construction is a variation of double knit, creating a smooth, reversible fabric that is soft and drapes well, often resembling a jersey knit but with greater stability and less tendency to run.

This classification distinguishes itself from its sibling category, 6006.41.00.85, which covers "Other" unbleached or bleached knitted or crocheted fabrics of artificial fibers. While this category is for specific constructions (double knit or interlock), the sibling category encompasses all other constructions of unbleached or bleached artificial fiber fabrics that do not meet the double knit or interlock criteria, such as single knit jersey or rib knits.

As a leaf node within the HTS system, this category does not have further subcategories. Therefore, the focus for classification within 6006.41.00.25 is on confirming that the fabric is indeed of artificial fibers, is in an unbleached or bleached state, and possesses the distinct characteristics of a double knit or interlock construction. Examples of materials falling under this classification would include polyester, nylon, or rayon fabrics knitted in a double knit or interlock structure.
