Asbestos; crocidolite (blue asbestos)

HS code 252410 covers crocidolite, also known as blue asbestos, a naturally occurring mineral that has been widely used in various industrial and construction applications due to its unique properties. As a highly durable and heat-resistant material, crocidolite asbestos has played a significant role in the global economy, particularly in the manufacturing, construction, and automotive industries. However, the health risks associated with asbestos exposure have led to increased regulation and a decline in its usage in many countries.

Crocidolite asbestos is primarily extracted from natural deposits through mining operations. The raw mineral is then processed, often through crushing, milling, and sorting, to separate the asbestos fibers from other impurities. The purified asbestos fibers are then used in the production of a wide range of products, including insulation materials, brake linings, and cement-based building materials.

The main inputs required for the crocidolite asbestos industry include the raw mineral deposits, mining and processing equipment, and energy sources to power the extraction and production processes. Additionally, the industry may rely on various chemical additives, binders, and other materials to incorporate the asbestos fibers into final products.

The primary outputs of the crocidolite asbestos industry are the processed asbestos fibers, which are then used as inputs for the manufacturing of a variety of products. These products may include 252010 (Asbestos, crude; asbestos fibers (crusted or fluffed)), 681110 Corrugated sheets of asbestos-cement, 681220 Boards, panels, tiles, and similar articles of asbestos-cement, and 681310 Brake linings and pads, among others.
