8413.82.00.00 - Liquid elevators 🖩

This HTS category, 8413.82.00.00, specifically covers "liquid elevators." Unlike pumps which actively move liquid through mechanical means such as impellers or pistons, liquid elevators operate on different principles. They are designed to raise liquids to a higher level without the direct application of mechanical force to the liquid itself. This often involves methods like pneumatic pressure, vacuum, or siphoning to facilitate the upward movement of the fluid.

The primary distinction between this category and its sibling, 8413.81.00 (Other pumps), lies in the fundamental mechanism of operation. While both deal with the movement of liquids, pumps employ direct mechanical action, whereas liquid elevators utilize indirect methods to achieve elevation. Therefore, an item will be classified under 8413.82.00.00 if its primary function is to lift liquids through pneumatic, vacuum, or similar non-mechanical force transfer principles, rather than through the direct displacement or impulsion of the liquid by moving parts.

As this is a leaf node within the HTS classification system, there are no further subcategories to explore under 8413.82.00.00. Classification at this level is definitive for liquid elevators. Examples of goods that would fall into this category include various types of vacuum or pressure-driven lifting devices used in industrial processes, laboratories, or for bilge pumping on vessels, provided they do not incorporate significant pumping mechanisms for direct liquid propulsion.
