HS Code for Uncut synthetic stones
HS code 710429 applies to synthetic or reconstructed precious and semi-precious stones, excluding diamonds, that are unworked or have only been roughly shaped or sawn. Synthetic stones are chemically and physically identical to their natural counterparts but are created in controlled environments. Reconstructed stones are formed by fusing together fragments of natural stones, often under high heat and pressure. This code is used for the raw materials of the synthetic gemstone industry, such as large boules of sapphire or ruby produced by the Verneuil process. These materials are destined for further cutting and polishing into finished gems or for use in industrial applications like laser components or watch bearings. The classification is distinct from natural stones (7103) and synthetic diamonds (710421). It requires clear identification of the stone's origin to ensure it is not misclassified as a natural mineral. Reconstructed stones, sometimes called pressed stones, are often confused with glass imitations. However, if the material is chemically identical to a natural stone, it remains in 7104. If it is merely glass, it falls under 7018. This code is vital for maintaining the integrity of the gemstone market by separating lab-created materials from natural ones and is essential for the electronics and precision instrument industries.

Common Misclassification
Common misclassifications include 710499, which is for worked (cut/polished) synthetic stones, and 710310, which is for natural unworked stones. Synthetic diamonds must be placed in 710421, not 710429. Glass imitations are classified under 7018.
FAQ
