Vermiculite, perlite and chlorites; unexpanded

HS code 253010 covers the trade of vermiculite, perlite, and chlorites in their unexpanded form. These naturally occurring minerals have a wide range of industrial applications, making them an important commodity in the global import/export market. Vermiculite and perlite, in particular, are valued for their unique physical properties, such as low density, high thermal insulation, and fire resistance, which make them essential raw materials for various manufacturing processes and construction activities.

The production of vermiculite, perlite, and chlorites typically involves mining and processing the raw materials. Vermiculite and perlite are extracted from open-pit mines, while chlorites are often found in underground deposits. The mined materials are then crushed, screened, and sometimes subjected to thermal treatment to expand their volume and enhance their desired properties. This expansion process is a crucial step in the production of these commodities, as it unlocks their full potential for various applications.

The main inputs required for the production of HS code 253010 commodities include the raw mineral deposits, mining equipment, and energy sources for the thermal expansion process. Vermiculite and perlite are typically found in volcanic regions, while chlorites can be extracted from metamorphic rock formations. In addition to the natural resources, the industry also relies on specialized machinery, such as crushers, screens, and furnaces, to extract, process, and transform the raw materials into the desired form.

The primary outputs of HS code 253010 are the unexpanded forms of vermiculite, perlite, and chlorites. These materials are then used as inputs for a wide range of industries, including 681310 construction materials, 842139 filtration equipment, and 854890 insulation products. The expanded versions of these minerals, which are classified under different HS codes, are often used in applications such as 681011 building materials, 842139 filter media, and 854890 thermal insulation.
