6505.00.90 - Other

This category, HTS Code 6505.00.90, "Other," specifically addresses headgear that is knitted or crocheted, or made up from lace, felt, or other textile fabric, but does not fall into the more specific material-based subcategories. This includes a wide array of headwear not primarily composed of cotton, flax, wool, or man-made fibers, as well as those where the primary fiber content is not readily identifiable for classification under those sibling categories. Examples could include novelty hats, ceremonial headwear, or specialized industrial head coverings where the textile composition doesn't align with the other listed options.

Distinguishing this category from its siblings is crucial for accurate classification. The sibling categories, such as "Of cotton, flax or both," "Of wool," and "Of man-made fibers," are defined by the predominant fiber content of the headgear. This "Other" category serves as a residual classification for headwear that does not meet the primary material requirements of those more specific groups, ensuring all knitted or crocheted textile headgear is accounted for within Chapter 65.

Within this "Other" category, further distinctions are made. One significant subdivision is for headwear containing 70 percent or more by weight of silk or silk waste, recognizing the unique properties and value of silk. The existence of this and other potential "Other" subdivisions indicates that even within this residual category, specific material compositions or intended uses may warrant further, more granular classification to ensure precise trade reporting and duty assessment.
