Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for rolling metal without removing material
Roller burnishing tools that size holes by displacement, not cutting, classify under 8207.40 separate from cutting reamers.
If hand-operated without power tool compatibility
Simple handtools like non-interchangeable blacksmith reamers fall under 8205 for other handtools.
If functioning primarily as a drill
Reamers with dominant drilling action over finishing classify as rock drills or similar in 8207.19.

Import Tips & Compliance
• 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
