Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If when assembled into drilling parts
Parts of drilling machinery incorporating diamonds classify under 8431 as finished equipment parts.
If optical or research grade
High-clarity synthetics for non-abrasive industrial uses may go to synthetic stones heading.
If knives or micro-drills
Worked diamonds as finished blades or cutters shift to Chapter 82 tools.
