6505.00.90.30 - Containing 70 percent or more by weight of silk or silk waste (759)

This HTS classification, 6505.00.90.30, specifically designates headwear that is constructed from textile materials and contains a significant proportion of silk. To fall under this subheading, the headgear must be composed of 70 percent or more by weight of silk or silk waste. This category is a specific subset within the broader classification for knitted or crocheted headgear, or headgear made up from lace, felt, or other textile fabric.

The defining characteristic of this subheading is its stringent material requirement. While other subcategories within 6505.00.90 might cover headwear made from various other textile blends or constructions, this particular code is exclusively for those predominantly made of silk. Therefore, headgear made from cotton, wool, synthetic fibers, or even silk blends with less than 70% silk content would be classified elsewhere.

As this is a leaf node in the HTS classification, there are no further subcategories. All headgear meeting the criteria of being made from textile fabric (knitted, crocheted, lace, felt, etc.), not in strips, and containing 70 percent or more by weight of silk or silk waste will be classified directly under this code. Examples include silk hats, caps, bonnets, and headbands that meet these precise material specifications.
