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
