Import Tips
• Provide engineering drawings confirming cross-sectional dimensions under 16 mm equivalent for wire-like profiles if applicable
• Label as 'structural' vs 'pressure' to prevent misclassification into line pipe headings
• Include country-of-melt certification, as alloy steel from certain origins may trigger anti-dumping duties
