Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If made with synthetic or polycrystalline diamonds
Subheading distinguishes natural vs synthetic diamond dies; synthetic falls under the broader carbide-mounted category.
If for use in continuous extrusion molding machines
If integrated into plastic or large-scale molding equipment, may classify as parts of extrusion machinery rather than standalone handtool dies.
If sold as interchangeable parts for rock drilling tools
Rock boring tools with diamond dies shift to base metal parts of earth boring tools if primarily for mining applications.

Import Tips & Compliance
• Verify diamond content certification to confirm classification as diamond die vs standard carbide under 8207.20.00.60
• Include technical specs and end-use documentation proving wire drawing application to avoid misclassification as jewelry tools
• Check for ITAR restrictions if dies exceed certain precision thresholds for defense-related wire production
