Import Tips
• Verify alloy steel certification (e.g
• AISI standards) with mill test reports to confirm classification under 7302.10.50
• Ensure compliance with AAR or EN standards documentation for U.S. rail import approvals
• Avoid misclassification as carbon steel by providing precise chemical composition analysis
