6210.20.90.30 - Having a fiber content of 70 percent or more by weight of silk or silk waste (734)

This HTS code, 6210.20.90.30, specifically classifies anoraks, windbreakers, and similar articles categorized as recreational performance outerwear. The defining characteristic for this classification is their fiber content, which must consist of 70 percent or more by weight of silk or silk waste. These garments are designed for outdoor activities where protection from the elements is paramount, embodying the performance aspect of outerwear.

This category is distinguished from its sibling, 6210.20.90.39, by its stringent material requirement. While both fall under recreational performance outerwear, the sibling category encompasses similar articles that do not meet the specific 70 percent silk or silk waste threshold. Therefore, the primary differentiator for this code lies in the predominant use of silk fibers in its construction.

As this is a leaf node within the HTS, there are no further subcategories. Classification is finalized at this level based on the product meeting the description of anoraks, windbreakers, or similar articles falling under recreational performance outerwear, and crucially, satisfying the 70 percent or more silk or silk waste fiber content requirement.
