5806.10.30.10 - Containing 85 percent or more by weight of silk or silk waste

This HTS classification, 5806.10.30.10, specifically covers narrow woven fabrics that are not otherwise specified in heading 5807. These fabrics are characterized by their pile construction, similar to woven pile fabrics such as terry toweling, or are chenille fabrics. Crucially, this particular subheading applies when the fabric contains 85 percent or more by weight of silk or silk waste. This material composition is the primary determinant for classification under this code.

Distinguishing this category from its siblings, 5806.10.30.20, which pertains to fabrics of wool or fine animal hair, and 5806.10.30.90, the "other" category for woven pile and chenille narrow fabrics, is essential. The defining characteristic here is the high silk content. Therefore, a narrow woven pile or chenille fabric that does not meet the 85% silk or silk waste threshold, or is primarily composed of wool or fine animal hair, would fall under a different subheading.

As this is a leaf node, there are no further subcategories. Classification decisions at this level are made by determining if a narrow woven pile or chenille fabric meets the 85% silk or silk waste threshold. If it does, it is classified under 5806.10.30.10. If it does not meet this material criterion, or if its primary composition is wool or fine animal hair, then alternative subheadings within 5806.10.30 would apply.
