7616.99.51.50 - Hangers and supports for pipes and tubes

This category, HTS 7616.99.51.50, specifically encompasses hangers and supports designed for pipes and tubes, manufactured from aluminum. These articles serve the functional purpose of holding, securing, or supporting cylindrical conduits, preventing their sagging, vibration, or misalignment. Examples include pipe clamps, brackets, U-bolts, and similar structural components intended for plumbing, industrial piping systems, or ventilation ductwork. The material of aluminum is a key defining characteristic for inclusion within this heading.

Distinguishing this classification from its siblings is crucial. Unlike laminated goods (7616.99.51.20) which involve multiple bonded aluminum sheets, or ladders (7616.99.51.30) and Venetian blinds (7616.99.51.40) with their distinct forms and functions, these hangers and supports are solely dedicated to the utility of pipe and tube accommodation. Their design prioritizes load-bearing and securing capabilities for cylindrical structures, rather than forming a surface, climbing aid, or light-filtering apparatus.

As this node represents a leaf node in the HTS, there are no further subdivisions. Classification within 7616.99.51.50 is determined by the article's primary function as an aluminum pipe or tube hanger or support. Importers should ensure that the product's design and intended use align with this specific function to avoid misclassification under broader "other" categories or more specialized aluminum articles within Chapter 76.
