Import Tips
• Provide flow diagrams and installation manuals to demonstrate hand-operation and prevent reclassification as automatic
• Label with maximum pressure and temperature ratings per ASME standards for compliance
• Avoid bundling with actuators; separate shipments prevent set classification issues
