Import Tips
• Obtain mill certificates confirming SAE 52100 grade and seamless production to prove suitability for bearing manufacture
• Include end-user statements from bearing producers to avoid misclassification as general tubing
• Watch for overlength shipments; ensure compliance with dimensional tolerances to prevent reclassification
