8512.40.20.00 - Defrosters and demisters

This HTS subheading, 8512.40.20.00, specifically classifies defrosters and demisters designed for use with cycles or motor vehicles. These devices are integral to automotive safety, functioning to either melt frost or prevent condensation from obstructing the driver's view. Typically, these units employ electrical heating elements or a fan-driven air circulation system to achieve their intended purpose, directly impacting visibility in adverse weather conditions.

This category is distinguished from its sibling, 8512.40.40.00, which covers windshield wipers. While both are motor vehicle accessories related to maintaining clear visibility, defrosters and demisters address issues of frost and fog, whereas wipers are designed to physically remove rain or snow. The primary function of clearing accumulated moisture or ice is the key differentiator.

As this subheading is a leaf node, it does not have further subdivisions. Therefore, classification under 8512.40.20.00 is determined by the article's explicit function as a defroster or demister for cycles or motor vehicles, and its electrical nature or design as a component thereof.
