Iodine

HS v2022 Code: 280120

About iodine

HS code 280120 covers the classification of iodine, a critical element with a wide range of industrial and medical applications. Iodine is a vital component in various industries, including pharmaceuticals, photography, and chemical manufacturing. Its importance extends beyond its direct uses, as it is also a key input for the production of other essential commodities, making it an integral part of the broader global economy.

Production process

Iodine is primarily extracted from natural sources, such as seawater, mineral deposits, and certain types of seaweed. The most common production method involves the oxidation of iodide ions to elemental iodine, which is then purified and refined for commercial use. This process can involve techniques like electrolysis, chemical precipitation, and distillation to ensure the purity and quality of the final product.

Production inputs

The production of iodine requires several key inputs, including seawater or mineral-rich brines, as well as specialized equipment and machinery for the extraction, purification, and refining processes. Additionally, the industry relies on a skilled workforce with expertise in chemical processing and manufacturing techniques.

Production outputs

The primary output of HS code 280120 is elemental iodine, which is then used as a raw material in the manufacture of a wide range of products, including 300490 Medicaments, 370790 Chemical preparations for photographic uses, and 281000 Oxides of boron, boric acids. Iodine is also an essential component in the production of various 290000 Organic chemicals and 380000 Miscellaneous chemical products.
