Brass Diaphragm Pressure Reducing Valve from Japan
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.

Import Tips
• 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
