Dolomite, not calcined or sintered; including dolomite roughly trimmed, or merely cut by sawing or otherwise into blocks or slabs of rectangular (including square) shape

HS code 251810 covers dolomite, a naturally occurring mineral composed of calcium magnesium carbonate. Dolomite is a versatile material with a wide range of industrial applications, including as a flux in steel production, a filler in the manufacture of plastics and rubber, and a source of magnesium. The dolomite industry plays a crucial role in supporting various sectors of the global economy, from construction and infrastructure to agriculture and chemical processing.

The production of dolomite covered under HS code 251810 typically involves mining, crushing, and sizing the raw material. Dolomite deposits are first extracted from quarries or mines using heavy machinery such as excavators and loaders. The extracted dolomite is then transported to processing facilities, where it undergoes crushing and screening to achieve the desired particle size and shape. In some cases, the dolomite may be further processed by cutting or trimming to produce blocks or slabs of rectangular or square shape.

The primary input for the dolomite industry under HS code 251810 is the raw dolomite mineral, which is extracted from natural deposits. In addition to the raw material, the industry requires various types of mining and processing equipment, such as excavators, crushers, and saws. Energy sources, such as electricity or diesel fuel, are also essential for powering the production machinery. Labor, transportation, and logistics services are other significant inputs required for the efficient operation of the dolomite industry.

The main output of the dolomite industry covered by HS code 251810 is dolomite in various forms, including crushed dolomite, dolomite blocks, and dolomite slabs. These dolomite products are then consumed by a wide range of industries, including 252010 Limestone flux; limestone and other calcareous stone, of a kind used for the manufacture of lime or cement, 281610 Hydroxide and peroxide of magnesium, 320910 Paints and varnishes based on synthetic polymers or chemically modified natural polymers, dispersed or dissolved in an aqueous medium, and 681011 Building blocks and bricks, of cement, concrete or artificial stone, among others.
