Import Tips
• Provide flow rate charts and pressure drop data to customs for proper flow control verification
• Label with maximum operating pressure and fluid compatibility to meet safety standards
• Avoid common pitfall of classifying as check valves (8481.30); confirm unidirectional flow isn't primary function
