Import Tips
• Verify exact diameter measurement and alloy composition certification to meet 'other alloy steel' criteria; ensure coils are irregularly wound, not straight lengths
• Provide mill test certificates (MTC) showing non-tool steel alloy elements
• Watch for reclassification if diameter under 19 mm
