Import Tips & Compliance
• Provide engineering drawings showing tolerances to confirm precision classification and avoid bulk pipe headings
• Label shipments clearly as 'seamless cold-drawn' with nonalloy steel grade (e.g
• 1018 or ST37) for CBP review
• Check for anti-dumping duties on specific steel tube origins; maintain country-of-melt documentation
