6003.20.10.00 - Open-work fabrics, warp knit (229)

This HTS category, 6003.20.10.00, specifically covers open-work fabrics that are produced using a warp knitting technique and are not exceeding 30 cm in width. The defining characteristic here is the "open-work" nature, indicating a fabric with deliberate holes or gaps, often achieved through specialized knitting patterns. These fabrics are distinct from other knitted or crocheted fabrics that might be made of cotton but lack this open-work construction or are not produced via warp knitting.

The primary distinction from its sibling category, 6003.20.30.00 ("Other"), lies in the specific inclusion of *warp knit* open-work fabrics. The sibling category would encompass other cotton fabrics of the specified width that do not meet the criteria of being both open-work and warp knitted. This could include weft knit open-work fabrics or other types of cotton knitted fabrics under heading 6003 that do not fit the specific open-work warp knit definition.

As this is a leaf node in the HTS classification system, there are no further subcategories branching from 6003.20.10.00. Therefore, the focus for classification purposes is on accurately identifying fabrics that are indeed warp knitted and exhibit an open-work construction, while being of cotton and within the specified width limitation. Examples could include certain types of lace-like fabrics or net fabrics manufactured using warp knitting methods.
