Import Tips
• Customs may require proof it's not 'high-strength steel'—ensure yield documentation complies with U.S
• Note (a)
• Use commercial invoices specifying exact dimensions to confirm 600 mm+ width criterion
• For bulk imports, segregate by grade to prevent blending with stainless or tool steel shipments
