Import Tips
• Label shipments clearly as 'spiegeleisen' with batch analysis; CBP often requires proof against high-strength steel misclassification
• Watch for partial remelting evidence which could reclassify as scrap under 7204
• Ensure weights per unit match primary form declarations (pigs/blocks)
