Import Tips

Label products clearly as 'low-pressure check valves' and provide max PSI rating (under 123 psi equiv. to 850 kPa) on packaging

Comply with NSF/ANSI 61 standards for potable water use; include certification docs to speed customs clearance

Avoid misdeclaration as brass if pure copper to match exact HTS copper definition
