Import Tips
• Verify alloy composition certification to confirm it qualifies as 'other alloy steel' and not tool or high-strength steel per chapter notes
• Provide mill test reports (MTRs) documenting chemical analysis to avoid reclassification during customs exam
• Watch for 'further worked' treatments like coating, which shift to 7225.99 subheadings if applicable
