Pearls, natural or cultured and unworked
CPC v2.1 Code: 3821
About pearls, natural or cultured and unworked
cpc code 3821 covers the classification of pearls, both natural and cultured, in their unworked state. Pearls are highly valued gemstones that have been prized for centuries, with a rich history in jewelry, fashion, and cultural traditions. This industry plays a significant role in the global gemstone and jewelry trade, contributing to the broader luxury goods sector and supporting livelihoods in pearl-producing regions around the world.
Production process
The production of pearls, whether natural or cultured, involves complex biological processes. Natural pearls are formed when a foreign object, such as a grain of sand, becomes trapped inside an oyster or mussel, which then coats the object with layers of nacre, creating the pearl. Cultured pearls are produced through a similar process, but with human intervention, where a nucleus is intentionally inserted into the mollusk to stimulate the pearl formation.
Production inputs
The main inputs required for the production of pearls, natural or cultured, include the mollusks (such as oysters and mussels) that serve as the host organisms, as well as the necessary equipment and facilities for pearl cultivation, harvesting, and processing. Additionally, specialized knowledge and expertise in pearl farming techniques are essential inputs for this industry.
Production outputs
The primary output of this industry is the pearls themselves, which are then used in a wide range of jewelry, fashion accessories, and other luxury products. The pearls produced under cpc code 3821 may be consumed by industries covered under other codes, such as 3813 Precious and semi-precious stones, unworked or simply sawn, cleaved or bruted and 3822 (Jewelry of gold, silver or platinum group metals (except watches and watch cases) and goldsmiths' or silversmiths' wares (including set gems)), which utilize pearls in their manufacturing processes.
