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
