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 valued for its hardness, durability, and resistance to weathering, making it a popular choice for construction, landscaping, and various industrial applications. As a key raw material in the building and construction industry, the quartzite trade plays a significant role in the global economy.

Quartzite is primarily extracted from quarries through a process of drilling, blasting, and excavation. The extracted blocks are then transported to processing facilities where they are cut, trimmed, and shaped into the desired sizes and forms, such as rectangular blocks or slabs. Advanced cutting techniques, including sawing and other methods, are employed to ensure the quartzite is processed into the required dimensions and finishes.

The main inputs for the quartzite industry include the raw quartzite deposits, as well as specialized machinery and equipment for extraction, cutting, and shaping the material. Energy sources, such as electricity or fuel, are also required to power the various stages of production. Additionally, skilled labor, including geologists, miners, and stone masons, is essential for the efficient and safe extraction and processing of quartzite.

The primary output of HS code 250620 is processed quartzite in the form of blocks, slabs, and other shaped products. These quartzite materials are then consumed by a range of industries, including 251012 Construction, 680221 Monumental or building stone, and 680229 Other worked monumental or building stone, where they are used for various construction, landscaping, and decorative applications.
