6505.00.60.40 - Containing 23 percent or more by weight of wool or fine animal hair (459)

This HTS subcategory specifically classifies headgear that is knitted or crocheted, or constructed from knitted or crocheted fabric, and is not made in part from braided materials. Crucially, these items must not contain any braid components, distinguishing them from headgear that incorporates braided elements. This classification encompasses a wide array of knitted or crocheted hats, caps, and other head coverings, provided they meet the material and construction criteria outlined.

Within the broader category of "Other" headgear not made up from braid, this specific subcategory focuses on articles where the primary textile construction is either knitting or crocheting. This contrasts with other potential "Other" classifications that might cover headgear made from woven fabrics, felt, or other non-knitted/crocheted textile constructions. The absence of braid is a defining characteristic that separates these items from potentially similar headgear that might include braided trims or structural elements.

As this is a leaf node, further subdivisions do not exist. Therefore, classification within this code hinges on a meticulous examination of the item's construction method. Items classified here will be exclusively made from knitted or crocheted fabrics or constructed through knitting or crocheting processes. Any presence of braided materials, even as trim, would likely lead to classification in a different HTS code, emphasizing the strict interpretation of "not in part of braid" for this particular designation.
