Import Tips
• Certify copper alloy composition (e.g
• C12200) meets water heater pressure standards per ASME codes
• Pair with tank diagrams showing manifold integration to substantiate 8419 classification over generic plumbing
• Avoid misdeclaration as pipe fittings; emphasize thermal expansion joints specific to heater operation
