Import Tips
• Submit detailed chemical composition reports to distinguish from stainless (Chapter 72 heading 7220) or specific alloys
• Ensure product is not in coils if intending 7225 classification; coiled products may go to 7225.99.0090
• Label shipments clearly as 'not further worked' to prevent misclassification into coated or clad categories
