HS Code for Rough industrial diamonds

Rough industrial diamonds are classified under HS code 7102.21. This classification falls under Chapter 71, which covers natural pearls, precious stones, and precious metals. Heading 7102 is specifically for diamonds. The Harmonized System distinguishes between industrial and non-industrial (gem-quality) diamonds based on their physical characteristics, such as color, transparency, and structural integrity. Industrial diamonds are those that, due to their flaws, color, or size, are unsuitable for use in jewelry and are instead intended for technical or industrial applications like cutting, grinding, or drilling. The suffix .21 indicates that the diamonds are 'unworked or simply sawn, cleaved or bruted.' This means they have not been polished or finished into final gemstones. The classification is strictly enforced to monitor the trade of industrial materials and to ensure compliance with international regulations like the Kimberley Process, which tracks the origin of rough diamonds.

Products Included

• Unworked industrial diamonds (boart)
• Simply sawn industrial diamond stones
• Cleaved industrial diamonds for tool tips
• Bruted industrial diamonds
• Carbonado (black diamonds) in rough form
• Industrial grade diamond crystals for drill bits

Common Misclassification

The most frequent misclassification occurs with HS code 7102.31, which is for non-industrial (gem-quality) rough diamonds. The distinction depends on the intended use and the physical grade of the stone. Another common error is using 7105.10, which is for diamond dust or powder. If the diamond is still in a stone or crystal form, even if small, it belongs in 7102.21. Furthermore, synthetic or laboratory-grown industrial diamonds must not be classified here; they belong under HS code 7104.21, which covers synthetic precious or semi-precious stones in an unworked state.

FAQ

What is the HS code for rough industrial diamonds?
