Thallium and articles thereof; unwrought thallium, powders

HS v2017 Code: 811251

About thallium and articles thereof; unwrought thallium, powders

hs code 811251 covers thallium and articles made from thallium. Thallium is a rare, soft, and malleable metal with a silvery-white appearance. It has a wide range of industrial applications, including the production of specialized electronic components, optical lenses, and certain types of alloys. As a strategic material, thallium plays a crucial role in various high-tech industries, contributing to the development of advanced technologies and supporting the broader economy.

Production process

Thallium is primarily produced as a by-product during the smelting of other metal ores, such as copper, zinc, and lead. The extraction process typically involves leaching the metal from the ore, followed by electrolytic or chemical separation to obtain pure thallium. Specialized techniques, such as zone refining, may be employed to further purify the metal and ensure its quality for specific applications.

Production inputs

The production of thallium and thallium-based products requires a reliable supply of thallium-containing ores or concentrates as the primary raw material. Additionally, the industry relies on various types of machinery and equipment, including smelting furnaces, leaching tanks, and electrolytic cells, to facilitate the extraction and purification processes. Skilled labor, energy sources, and specialized chemicals may also be significant inputs for this industry.

Production outputs

The main outputs of hs code 811251 are unwrought thallium and thallium powders. These materials are then used as inputs for the manufacture of a wide range of products, including 854389 electronic components, 900190 optical lenses, and specialized alloys. The thallium produced under this code may also be used in the production of 282619 other inorganic compounds and 284590 other inorganic acids and other inorganic oxygen compounds of non-metals.
