Import Tips
• Use internationally recognized standards (e.g
• ASTM E1019) for analysis methods in documentation
• Segregate high-purity from standard grades in same container to prevent cross-contamination claims
• Pre-notify CBP for large-volume shipments; ferroniobium often subject to additional steel import monitoring
