Import Tips
• Submit oxygen content analysis certificates; levels above 50 ppm may reclassify as ETP rather than OFHC
• Use ISRI scrap specifications if importing recycled content billets to qualify for lower duties
• Label as 'not for remelting into alloys' to prevent heading 7405 master alloy classification
