A visor or peak that is a component intended for incorporation into a hat or cap classifies under heading 6507. A finished, wearable sun visor designed to be worn on its own as headgear would instead classify under the appropriate finished headgear heading (such as 6506), since it functions as a complete article rather than a component.

Heading 6507 covers headbands in the context of hat-making components (i.e., the interior band sewn inside a hat). Athletic sweatbands worn on the forehead or wrist as standalone accessories generally classify under textile accessory headings rather than 6507, since they are not components of headgear construction. The intended use and design of the article are the key factors.
