Import Tips
• Specify cobalt content percentage (>5%) on commercial invoice for alloy classification; common error is listing as plain HSS
• Include end-user certificates if for aerospace to preempt ITAR concerns, even for non-gun reamers
• Bundle in sets under statistical note for piece count reporting; avoid splitting shipments to manipulate duties
