Impreg Diamond Rotary Rock Drill Bit
A rotary rock drill bit featuring impregnated synthetic diamonds in a tungsten carbide matrix for hard rock drilling in mining operations. It falls under HTS 8207.19.30.60 due to its classification as a rotary rock drill bit with cutting edges containing over 0.2% tungsten by weight. Designed for high-penetration rates in abrasive formations like quartzite.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If cutting part has lower alloy content
Bits with 0.2% or less chromium/molybdenum/tungsten and 0.1% or less vanadium fall into the general 'other' category without specific alloy specs.
If sold as unfinished base metal parts
Unassembled or incomplete cutting edges without diamonds/tungsten carbide are classified as parts rather than complete rock drilling tools.
If imported as complete drilling rig component set
When assembled with mounting adapters for specific earth boring machinery, classification shifts to parts of boring machines under Chapter 84.

Import Tips & Compliance
• Verify alloy composition certificates to confirm chromium, molybdenum, tungsten, or vanadium thresholds for subheading compliance
• Ensure bits are specifically designed for rock drilling to avoid reclassification as machine tool accessories
• Provide drilling application documentation during customs valuation
