Import Tips
• Provide NSF/ANSI 61 certification for potable water contact to ensure regulatory compliance
• Declare exact dimensions and pressure ratings; undersized washers risk reclassification as fittings under 3917
• Bundle in sets only if for retail; bulk shipments may trigger different valuation rules
