Natural calcium phosphates, natural aluminium calcium phosphates and phosphatic chalk; ground

HS code 251020 covers natural calcium phosphates, natural aluminium calcium phosphates, and phosphatic chalk that have been ground. These materials are essential raw materials for various industries, including agriculture, fertilizer production, and chemical manufacturing. They play a crucial role in the global economy, providing key inputs for the production of essential goods and supporting food security and sustainable development.

The production of the materials covered under HS code 251020 typically involves mining and processing of natural deposits. The raw materials are extracted from the earth, crushed, and then ground to the desired particle size. This process may also involve beneficiation techniques, such as flotation or chemical treatment, to improve the purity and quality of the final product.

The main inputs required for the production of the materials covered under HS code 251020 are the natural deposits of calcium phosphates, aluminium calcium phosphates, and phosphatic chalk. Additionally, the production process may require specialized mining and processing equipment, as well as energy sources and water for various stages of the operation.

The materials produced under HS code 251020 are primarily used as raw materials in the production of 310100 Mineral or chemical fertilizers, nitrogenous, 310510 Mineral or chemical fertilizers containing two or three of the fertilizing elements nitrogen, phosphorus and potassium, and 281800 Artificial corundum, whether or not chemically defined; aluminium oxide; aluminium hydroxide. These materials are also used in the production of various chemicals, ceramics, and other industrial applications.
