Import Tips
• Provide chemical analysis confirming tool steel elements (C, Mn levels) to CBP; mismatches lead to 7228.50.30 reclassification
• Ensure no heat treatment beyond cold-finishing; annealed condition only, as quenched/tempered may affect alloy steel heading
• Label dimensions clearly; max cross-section determines statistical suffix within 7228.50.10
