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
