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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If suitable for gemstone use based on clarity and color
Diamonds of high quality, even if simply sawn, are reclassified as unsorted or boulders for jewelry under 7102.10 if they meet gem standards.
If further worked beyond simple sawing, like preliminary polishing
Any additional working such as shaping or polishing moves them out of 'simply sawn' into worked industrial diamonds category.
If manufactured into industrial grinding or cutting tools
Once incorporated into millstones, grindstones, or similar abrasive articles, classification shifts to Chapter 68 for worked products.

Import Tips & Compliance
• Obtain Kimberley Process Certificate for all diamond shipments to comply with US import regulations against conflict diamonds
• Provide detailed documentation on sawing process to distinguish from more worked diamonds under 7102.29
• Avoid misclassification as gem diamonds (7102.10) by specifying industrial end-use in invoices and certificates

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.
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.
