CPC v2.1 Code: 3456

About synthetic or reconstructed precious or semi-precious stones, unworked

cpc code 3456 covers the production and trade of synthetic or reconstructed precious and semi-precious stones in their unworked state. These materials are increasingly important in the jewelry, electronics, and industrial sectors, providing a more affordable and consistent alternative to naturally-occurring gemstones. As a key input for a wide range of downstream industries, this segment plays a vital role in the broader global economy.

Production process

Synthetic and reconstructed precious and semi-precious stones are produced through a variety of advanced manufacturing techniques. Common methods include crystal growth, chemical vapor deposition, and high-temperature/high-pressure processes. These techniques allow for the precise control of the stone's chemical composition, physical properties, and visual characteristics, enabling the creation of consistent, high-quality products.

Production inputs

The production of cpc code 3456 items requires access to specialized raw materials, equipment, and expertise. Key inputs include high-purity chemical precursors, sophisticated growth chambers and furnaces, as well as skilled technicians and engineers to operate the complex manufacturing processes. Additionally, significant investments in research and development are needed to continually improve production methods and product quality.

Production outputs

The primary outputs of cpc code 3456 are synthetic and reconstructed diamonds, rubies, sapphires, emeralds, and a range of other precious and semi-precious stones. These materials are then consumed by a variety of downstream industries, including 3813 Jewelry and related articles, 2670 Electronic components, and 2391 Abrasive products, among others. The consistent quality and availability of these synthetic gemstones have made them an increasingly valuable resource for manufacturers across multiple sectors.
