Import Tips
• Submit detailed alloy analysis reports confirming note (e)(iii) criteria to CBP upon entry
• Label coils clearly as 'tool steel' with grade; mislabeling can lead to 7213 reclassification
• Check for any further working (e.g
• polishing) which excludes from hot-rolled heading per chapter notes
