Bruted Girdle Rough Diamonds for Abrasives
Rough industrial diamonds with bruted (rounded) girdles created by basic friction process, used in abrasive powders and coatings. HTS 7102.21.30.00 applies to these simply bruted diamonds for industrial purposes, distinguishing from gemstone preparation. Bruting here is minimal and not for jewelry faceting.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If synthetic rather than natural diamonds
Synthetic industrial diamonds, even simply sawn or bruted, classify under Chapter 71 heading 7104.
If cut into specific industrial shapes beyond bruting
More advanced shaping for tools moves to 'other worked' industrial diamonds subheading.
If strung as industrial rosary or garland for tools
Diamonds strung together for manufacturing use classify as 'other' articles of precious metal/stones.

Import Tips & Compliance
• Declare exact bruting method and dimensions to avoid disputes over 'simple' vs advanced working
• Pair with end-user letters confirming industrial abrasive application for smooth CBP review
• Watch for alloy contamination; if mixed with binders over 2%, may shift to other chapters
Related Products under HTS 7102.21.30.00
Simply Sawn Industrial Rough Diamonds
Rough diamonds that have undergone simple sawing to create flat surfaces, primarily used in industrial applications like cutting tools and abrasives. These fall under HTS 7102.21.30.00 as they are simply sawn diamonds, not further worked, and classified as industrial grade rather than gem quality. They meet the criteria for 'simply sawn' without advanced faceting or polishing.
Cleaved Bort Industrial Diamonds
Bort diamonds (low-quality fragments) that are simply cleaved for industrial crushing and abrasive production. HTS 7102.21.30.00 covers these minimally processed industrial diamonds, explicitly excluding mounted or set forms. Cleaving separates natural cleavages for efficient processing.
Bruted Cubic Industrial Diamond Fragments
Industrial diamond fragments bruted into cubic shapes for use in diamond drilling bits. Falls under HTS 7102.21.30.00 as simply bruted, unworked industrial diamonds not suitable for gems. Bruting rounds edges minimally for handling and tool fitting.
Cleaved Octahedral Industrial Diamonds
Industrial diamonds cleaved along natural octahedral planes to produce usable shapes for drilling and grinding applications. Classified under HTS 7102.21.30.00 as 'simply cleaved' unworked diamonds intended for industrial use, without mounting or setting. Cleaving is a minimal processing step that does not constitute advanced working.
Sawn White Industrial Diamond Slabs
White industrial-grade diamonds sawn into slabs for use in wire saws and precision cutting tools. These qualify under HTS 7102.21.30.00 as simply sawn, unmounted diamonds for non-gem purposes. The sawing is basic, creating parallel faces without further refinement.
