6003.30.10.00 - Open-work fabrics, warp knit (229)

This classification covers open-work fabrics that are knitted using the warp knitting technique and are composed of synthetic fibers. Warp knitting is a method where yarns are interlaced in a zigzag pattern to create stable, non-laddering fabrics, often with an open or mesh-like structure. Examples include various types of lace, mesh, and net fabrics made from synthetic materials such as polyester, nylon, or acrylic. The width of these fabrics is not specified in this particular sub-heading, but the general chapter scope indicates they are not of heading 6001 or 6002.

Within this level, 6003.30.10.00 is specifically for open-work warp knit fabrics of synthetic fibers. Its sibling category, 6003.30.60.00, covers "Other" knitted or crocheted fabrics of synthetic fibers that do not meet the specific criteria for open-work warp knit fabrics under 6003.30.10.00. This distinction hinges on whether the fabric exhibits an open-work structure and is produced via warp knitting.

As this is a leaf node, there are no further subcategories under 6003.30.10.00. Therefore, the focus for classification under this code is to ensure the fabric is indeed of synthetic fibers, exhibits an open-work design, and is produced through the warp knitting method. If a fabric of synthetic fibers is knitted or crocheted but does not fit these specific characteristics, it would likely be classified under the "Other" sibling category.
