Import Tips
• Provide mill test certificates proving carbon steel composition to prevent reclassification as stainless or alloy steel
• Label with maximum pressure and temperature ratings to comply with ASME standards and facilitate CBP review
• Bundle with installation instructions but avoid packaging as sets to maintain individual valve classification
