Import Tips & Compliance
• Present material test reports showing Ni>10% but steel matrix dominant to justify 7304 vs 7506 classification
• Include ASME Section II material spec sheets for alloy verification during entry
• Separate from carbon steel shipments to avoid commingling and classification disputes
