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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If synthetic or cultured
Synthetic industrial diamonds are classified in heading 7104, separate from natural diamonds regardless of use.
If already manufactured into grinding wheels or tools
Diamonds worked into finished millstones, grindstones, or drilling tools shift to Chapter 68 as worked articles.
If suitable for industrial use but non-miners' type (e.g., larger rough)
Other industrial diamonds not specified as miners' diamonds fall under 7102.31, based on size and quality distinctions.

Import Tips & Compliance
• Obtain certificates of origin and industrial use declarations to distinguish from gem-quality diamonds and avoid reclassification
• Declare exact carat weight and confirm unworked status; improper documentation can lead to audits by Customs
• Avoid common pitfalls like mixing with synthetic diamonds, which fall under different subheadings
