Import Tips
• Submit chemical composition analysis confirming alloy elements (e.g
• chromium >1.00%) to distinguish from carbon steel equivalents
• Ensure end-use declarations specify oil/gas pipeline application to avoid general pipe headings
• Pre-clear with CBP rulings for normalized/heat-treated pipes, as processing state can affect valuation
