Products classified under HTS 7102.29.00.20
Rough Miners' Diamonds for Drilling Bits
Unworked natural diamonds specifically sourced for industrial use in manufacturing drill bits and cutting tools. Classified under HTS 7102.29.0020 as 'other miners' diamonds' due to their role in mining and drilling operations, not suitable for gem purposes. These diamonds are valued for their hardness in abrasive applications.
Bort Miners' Diamonds for Saw Blades
Crushed and irregular bort diamonds classified as miners' diamonds for embedding in industrial saw blades used in stone cutting. Falls under HTS 7102.29.0020 as other unmounted, unworked industrial diamonds specifically for mining tools. Their low clarity makes them ideal for high-wear abrasive applications.
Rough Octahedral Miners' Diamonds
Natural rough octahedral crystals designated as miners' diamonds for high-pressure drilling in oil and gas exploration. HTS 7102.29.0020 covers these other industrial diamonds due to their unmounted, unworked state and mining-specific application. Ideal for polycrystalline diamond compact production.
Industrial Cleavage Miners' Diamonds
Rough cleavage fragments of miners' diamonds used in geological drilling and core sampling equipment. HTS 7102.29.0020 applies to these other unmounted industrial diamonds optimized for mining exploration. They provide superior cutting performance in harsh subsurface conditions.
Crushed Miners' Diamonds for Abrasive Mining Tools
Coarsely crushed natural miners' diamonds for use in manufacturing abrasive tools for coal and mineral mining. These are unworked, unmounted, and classified under HTS 7102.29.0020 as other industrial miners' diamonds. Their durability supports heavy-duty excavation tasks.
Boart Miners' Diamonds for Tunneling Equipment
Irregular boart diamonds for tunnel boring machine cutters in underground mining operations. These unworked miners' diamonds fall under HTS 7102.29.0020 as other industrial variants. Their toughness excels in rock penetration tasks.
