8413.81.00.30 - Household water systems, self-contained; and windmill pumps

This HTS classification covers specific types of pumps designed for household use or for the utilization of wind power. It specifically includes self-contained household water systems, which are integrated units designed to draw, treat, and/or distribute water within a domestic setting. Additionally, this category encompasses windmill pumps, which are mechanical devices powered by wind to move water, typically for agricultural or domestic supply purposes. The defining characteristic is their intended application in either a residential context or through wind-driven mechanisms.

It is important to distinguish this category from its siblings. While 8413.81.00.20 is dedicated to turbine pumps, which rely on rotating impellers to generate flow, this category focuses on the end-use or power source rather than the specific pumping mechanism. Turbine pumps can be used in household systems or windmills, but their classification is determined by their operational type in that sibling category. Therefore, 8413.81.00.30 isolates those systems and pumps based on their distinct application.

As a leaf node, this classification does not have further subcategories. The distinction between household water systems and windmill pumps is the primary focus for classification within this specific HTS code. Importers and exporters should ensure the goods clearly fit either the self-contained household water system or windmill pump description to correctly utilize this code, considering their design, function, and intended place of use.
