Import Tips
• Label with exact alloy grade and dimensions; CBP may require verification against ASTM A29 specs
• Avoid misclassification as tool steel (7228.70) by confirming it doesn't meet chapter note (e) element thresholds
• Include heat treatment records if normalized, as quenching doesn't count as 'further worked' but affects end-use docs
