Import Tips
• Include heat treatment records proving compliance with ASTM standards to satisfy technical verification
• Declare exact alloy composition to distinguish from carbon steel rates and avoid anti-dumping scrutiny
• Use proper packing to prevent distortion during transit, as customs may inspect for damage-related reclassification
