Quartzite; whether or not roughly trimmed or merely cut, by sawing or otherwise, into blocks or slabs of a rectangular (including square) shape

HS code 250620 covers the classification of quartzite, a type of metamorphic rock formed from sandstone. Quartzite is a highly durable and versatile material with a wide range of applications in the construction, manufacturing, and industrial sectors. As a key raw material, the quartzite industry plays a vital role in supporting economic growth and development across various industries that rely on its unique properties and characteristics.

The production of quartzite typically involves the extraction of the raw material from quarries or mines, followed by various processing steps. These may include crushing, cutting, trimming, and shaping the quartzite into the desired blocks or slabs. Advanced techniques, such as sawing or other cutting methods, are often employed to ensure the quartzite is prepared in the required rectangular (including square) shape, as specified by the HS code.

The primary input for the quartzite industry is the raw quartzite material, which is sourced from natural deposits. In addition to the raw material, the industry also requires specialized machinery and equipment for the extraction, processing, and shaping of the quartzite. Energy sources, such as electricity or fuel, are also necessary to power the various production processes. Labor, transportation, and other supporting infrastructure are also important inputs for the efficient operation of the quartzite industry.

The primary output of the quartzite industry covered by HS code 250620 is the production of quartzite blocks and slabs in rectangular (including square) shapes. These quartzite products are then consumed by a wide range of industries, including 251610 Building stone for construction and architectural applications, 680221 Monumental or building stone, worked, and articles thereof, simply cut or sawn, with a flat or even surface for decorative and landscaping purposes, and 680291 Monumental or building stone, worked, and articles thereof, other than simply cut or sawn, with a flat or even surface for more specialized or value-added quartzite products.
