Import Tips
• Chemical analysis reports are crucial to prove 'other alloy steel' status vs carbon or stainless steel
• Verify no internal/external welds via non-destructive testing records to maintain seamless classification
• For bundles, ensure packing lists specify individual pipe dimensions to avoid set classification issues
