8516.90.05.00 - Of heaters or heating apparatus of subheading 8516.10, 8516.21 or 8516.29

This HTS category, 8516.90.05.00, specifically covers parts for electric heating apparatus falling under subheadings 8516.10 (electric instantaneous or storage water heaters and immersion heaters), 8516.21 (electric space heating apparatus incorporating a fan), and 8516.29 (other electric space heating apparatus). This includes components such as heating elements, thermostats, casings, and control mechanisms designed for these types of heaters.

It is crucial to distinguish this category from its siblings. For instance, while 8516.90.15.00 and 8516.90.25.00 cover specific housings for hand dryers and flatirons, respectively, this category is broader and encompasses parts for a wider range of electrothermic heating devices. Similarly, other sibling categories are dedicated to parts for toasters, microwave ovens, or cooking stoves, clearly defining their scope and excluding the general heating components found here.

As this is a leaf node, there are no further subcategories to introduce. The classification of parts under 8516.90.05.00 relies on their direct association with and intended use in the electric water heaters, immersion heaters, or electric space heaters described in the parent subheadings. Therefore, classification hinges on identifying the specific function of the part in relation to these broader heating appliances.
