Import Tips
• Label with precise dimensions; CBP measures maximum cross-section—over 18mm triggers different rate
• Include heat analysis certificate proving tool steel elements per note (e) to prevent fallback to generic alloy steel
• Avoid bundling with further-worked items; separate shipments reduce misclassification risk
