HS Code for Uncut diamonds
HS code 710421 is used for synthetic diamonds that are in their primary, unworked state. Synthetic diamonds, also known as laboratory-grown or cultured diamonds, are produced using technological processes such as High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD). This specific code covers these stones when they have only been roughly shaped, sawn, or cleaved from the original growth crystal. They have not yet been faceted, polished, or prepared for setting into jewelry. The classification is vital for customs and trade monitoring to differentiate between natural mineral diamonds and those created through industrial means, as well as to distinguish between raw materials and finished gemstones. Because synthetic diamonds have the same physical and chemical properties as natural diamonds, documentation such as laboratory reports is often required to justify the use of heading 7104 instead of 7102. This code ensures that the trade of lab-grown rough is tracked separately from the natural diamond supply chain. The unworked status is strictly interpreted. If a synthetic diamond has been laser-cut into a specific shape that resembles a finished gemstone, it may be moved to 710491. This code is primarily for the industrial rough that serves as the starting point for the jewelry or abrasive manufacturing sectors.
Products Included
- Lab-grown diamond rough crystals
- Sawn synthetic diamond blocks
- Roughly shaped laboratory diamonds
- Unworked HPHT or CVD diamond seeds
Common Misclassification
The most frequent misclassification is with 710210, which is for natural uncut diamonds. It is also confused with 710491, which covers synthetic diamonds that have been worked (cut or polished). Industrial-grade synthetic diamond powder should be classified under 710510.
