6006.90 - Other:

This HTS category, 6006.90, encompasses knitted or crocheted fabrics that do not fall under the more specific classifications based on wool, fine animal hair, cotton, synthetic, or artificial fibers. Essentially, it serves as a residual category for other types of knitted or crocheted fabrics, meaning that if a fabric's primary material composition does not align with the preceding subheadings in heading 6006, it will likely be classified here.

To distinguish this category from its siblings, it's important to note that categories such as 6006.10.00.00 specifically cover fabrics of wool or fine animal hair. Similarly, other sibling categories are designated for fabrics predominantly composed of cotton, synthetic fibers, or artificial fibers. Therefore, 6006.90 is applicable when the fabric is not primarily made of these specified materials.

The subcategories within 6006.90 further refine the classification based on material. Specifically, 6006.90.10.00 is designated for fabrics containing 85 percent or more by weight of silk or silk waste, recognizing this as a distinct and important textile material. The residual category, 6006.90.90.00, is for all other knitted or crocheted fabrics not otherwise specified, including those made from a blend of materials where no single component meets the 85% threshold for silk, or fabrics made from other fibers not listed in prior subheadings.
