8419.90.10.00 - Of instantaneous or storage water heaters 🖩

This HTS category, 8419.90.10.00, specifically covers parts and accessories that are integral to the functioning of instantaneous or storage water heaters, but not those that are electric. This means components such as tanks, heating elements (when not part of a broader appliance covered elsewhere), thermostats, safety valves, and housings designed exclusively for these nonelectric water heating devices fall under this classification. The classification is determined by the specific design and intended use of the part in relation to these nonelectric water heating units.

Distinguishing this category from its siblings is crucial. While other categories under 8419.90 address parts for machinery involved in material treatment processes, or specifically parts of heat exchange units, 8419.90.10.00 is narrowly focused on components dedicated to water heaters that operate without electricity. For instance, parts for machinery used in drying or sterilizing materials, or components of general heat exchangers, would not be classified here even if they involve temperature change. This section is exclusively for components of devices whose primary function is the heating of water for immediate or storage use, without electrical power input.

As this is a leaf node in the HTS structure, there are no further subcategories to introduce. Therefore, classification decisions within 8419.90.10.00 will rely on a detailed examination of the part's construction, material, and its direct relationship and essentiality to the operation of a nonelectric instantaneous or storage water heater, ensuring it is not classifiable as a finished product under heading 8419 itself or as a more general component under other 'Other' parts categories.
