8402.12.00.00 - Watertube boilers with a steam production not exceeding 45 t per hour 🖩

This HTS category, 8402.12.00.00, specifically classifies watertube boilers designed for generating steam where the maximum steam production capacity does not exceed 45 metric tons per hour. Watertube boilers are characterized by having water flow through tubes which are heated externally. These boilers are commonly employed in various industrial applications where controlled steam generation is required, such as in smaller manufacturing plants, food processing facilities, or for process heating.

It is crucial to distinguish this category from its sibling, 8402.11.00.00, which covers watertube boilers with a steam production capacity exceeding 45 metric tons per hour. The defining factor for classification here is the throughput capacity of the boiler. Another sibling, 8402.19.00.00, encompasses other types of vapor generating boilers, including hybrid designs, which are not exclusively watertube boilers. Therefore, classification within 8402.12.00.00 hinges on both the construction type (watertube) and the specified steam output limit.

As this is a leaf node within the HTS structure, there are no further subcategories. Classification at this level is definitive based on the product meeting the criteria of being a watertube boiler with a steam production capacity not exceeding 45 tons per hour. Practical considerations for classification include verifying the manufacturer's specifications regarding steam output and confirming the boiler's internal design features consistent with watertube construction.
