Import Tips
• ASME/ASTM specs (e.g
• B704) must accompany shipment; common issue is misdeclaration as nickel alloy excluding steel base
• Verify 'other alloy steel' status via melting practice certificates; Inconel blends can border Chapter 75 nickel products
• Pressure test reports help prove hydraulic end-use without reclass to machinery parts
