6002.90.80.20 - Open-work fabrics, warp knit (222)

This HTS category, 6002.90.80.20, specifically classifies open-work fabrics that are produced using a warp knitting technique. The defining characteristic of this subcategory is its open construction, meaning it has deliberate holes or gaps in its fabric structure, often achieved through specialized knitting machinery and stitch formations. These fabrics are typically made with a significant content of elastomeric yarn or rubber thread, exceeding 5% by weight, and are not of the pile or loop forms covered by heading 6001.

Within the broader category of "Other" knitted or crocheted fabrics not exceeding 30 cm in width and containing elastomeric yarn or rubber thread, this classification differentiates itself from its sibling, 6002.90.80.80. While both fall under the "Other" designation at this level, 6002.90.80.20 is exclusively for warp-knitted open-work fabrics. The sibling category, 6002.90.80.80, would encompass any other "other" knitted or crocheted fabrics within the scope that are not open-work and warp-knitted, such as plain knit fabrics or those with different construction methods.

As this is a leaf node in the HTS classification, there are no further subdivisions. Therefore, the focus for classification under 6002.90.80.20 is on the precise identification of an open-work fabric where the knitting method is warp knitting, and it meets the material composition and width requirements of its parent categories. Examples include certain types of lingerie fabrics, decorative mesh fabrics, and specialized athletic wear materials where breathability and flexibility are key attributes.
