5601.29.00.10 - Containing 85 percent or more by weight of silk or silk waste

This HTS classification pertains to wadding composed primarily of textile materials, specifically those containing 85 percent or more by weight of silk or silk waste. This category encompasses a variety of lightly matted or compressed fiber materials used for padding, filling, or insulation purposes. The key distinguishing factor for classification under 5601.29.00.10 is the significant silk content, which dictates its inclusion and valuation for customs purposes.

This specific subheading is differentiated from its siblings by the material composition. While other categories within 5601.29.00 may cover wadding of wool, fine animal hair, or other unspecified textile materials, this classification exclusively applies to products where silk or silk waste is the dominant component. This precise material threshold ensures accurate tariff application and avoids confusion with materials that have lesser silk content or are made from entirely different fibers.

As this is a leaf node within the HTS, there are no further subcategories to introduce. Therefore, the classification relies directly on the specified material content. Practical application would involve verifying the weight percentage of silk or silk waste within the wadding to confirm its correct placement under this tariff item. Examples of goods that could fall here include silk-filled quilt batting or silk-derived stuffing materials for various textile articles, provided they meet the 85% silk or silk waste threshold.
