Boron; tellurium

HS v2017 Code: 280450

About boron; tellurium

HS code 280450 covers the classification of boron and tellurium, two essential elements with diverse industrial applications. Boron is a metalloid with unique chemical properties, while tellurium is a rare metalloid with semiconductor and thermoelectric properties. These elements play crucial roles in various industries, from electronics and energy production to specialty glass and ceramics manufacturing, making them important commodities in the global trade landscape.

Production process

Boron is primarily produced through the reduction of boric acid or borax, while tellurium is typically extracted as a by-product during the processing of copper, gold, and other metal ores. The production of these elements involves complex chemical and metallurgical processes, often requiring high temperatures, specialized equipment, and strict quality control measures to ensure the purity and consistency of the final products.

Production inputs

The production of boron and tellurium requires a range of raw materials, including various boron-containing minerals, copper and other metal ores, as well as specialized machinery and equipment for processing, refining, and purifying the elements. Additionally, the production process may involve the use of various chemicals, energy sources, and other supporting resources to facilitate the extraction, separation, and refinement of these elements.

Production outputs

The outputs of HS code 280450 are primarily boron and tellurium, which are then utilized in a wide range of industries. Boron finds applications in the production of 701931 borosilicate glass, 854389 electronic components, and 284700 fertilizers, among others. Tellurium, on the other hand, is used in the manufacture of 850231 photovoltaic cells, 852990 electronic devices, and 854011 thermoelectric materials.
