Import Tips & Compliance
• Ensure the slabs are not further worked than hot-rolled or forged, as additional processing may change classification
• Provide a certificate of analysis confirming the nickel content (63-70%) to support the high-nickel alloy steel classification
• Consider whether the copper content affects the classification under Chapter 74
