Brass Diaphragm Pressure Reducing Valve
A brass-constructed diaphragm-type valve designed to automatically reduce high inlet water pressure to a lower outlet pressure for residential plumbing systems. It falls under HTS 8481.10.0090 as a pressure-reducing valve not specified elsewhere in the subheading, used for pipes and tanks in non-industrial applications. The diaphragm mechanism responds to downstream pressure changes to maintain steady output.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If lacks automatic pressure regulation
Valves without pressure-reducing function are classified as other taps, cocks, or valves in 8481.80, based on function rather than pressure control.
If includes check valve functionality
Combined pressure-reducing and check valve assemblies may shift to 8481.30 for check valves if prevention of backflow is primary purpose.
If designed as pump parts
Parts specifically for pumps, including certain pressure regulators, fall under Chapter 84 pump parts rather than general valves.

Import Tips & Compliance
• Verify valve pressure ratings and material composition for accurate HTS classification; obtain manufacturer's test certificates for pressure performance
• Ensure compliance with NSF/ANSI 61 standards for potable water use to avoid customs holds
• Common pitfall: misclassifying as a simple tap under 8481.80
