Import Tips
• Verify exact weight and gray iron composition via material certificates to confirm 8455.30.0015 eligibility and avoid reclassification to lighter rolls
• Obtain mill test reports proving suitability for rolling mills, as general castings may shift to Chapter 73
• Ensure proper documentation of end-use in metalworking to prevent customs disputes over industrial vs. general machinery parts
