Asbestos; other than crocidolite (blue asbestos)

HS code 252490 covers the import and export of asbestos, excluding the blue variety known as crocidolite. Asbestos is a naturally occurring mineral fiber that has been widely used in various industries due to its exceptional heat-resistant and insulating properties. This industry plays a crucial role in the construction, automotive, and manufacturing sectors, providing essential materials for a range of applications.

The production of asbestos involves the mining and processing of asbestos-containing rock. The raw asbestos is extracted from the earth, sorted, and then processed through a series of steps, including crushing, milling, and purification, to produce the desired fiber grades. The specific production techniques may vary depending on the type of asbestos and the intended end-use applications.

The main inputs required for the asbestos industry include the raw asbestos ore, which is the primary raw material. Additionally, the industry relies on specialized mining and processing equipment, as well as energy sources, such as electricity and fuel, to power the production facilities. Transportation infrastructure is also a crucial input, as the asbestos needs to be transported from the mining sites to the processing facilities and ultimately to the end-users.

The primary output of the asbestos industry is the processed asbestos fiber, which is then used in a variety of applications. These include the manufacture of 252010 Asbestos cement, 681181 Friction materials, and 681182 Articles of asbestos-cement, of cellulose fiber-cement or the like. The asbestos fibers may also be used in the production of 681189 Other articles of asbestos; articles of mixtures with a basis of asbestos or of mixtures with a basis of asbestos and magnesium carbonate, as well as in the insulation and fire-resistant materials industries.
