Bricks, blocks, tiles and other ceramic goods of siliceous fossil meals (e.g. kieselguhr, tripolite or diatomite) or of similar siliceous earths

HS v2022 Code: 6901

About bricks, blocks, tiles and other ceramic goods of siliceous fossil meals (e.g. kieselguhr, tripolite or diatomite) or of similar siliceous earths

HS code 6901 covers a diverse range of ceramic products made from siliceous fossil meals, such as kieselguhr, tripolite, or diatomite, as well as other similar siliceous earths. These materials are valued for their unique properties, including high porosity, low thermal conductivity, and chemical inertness. The products classified under this code are widely used in a variety of industries, from construction and insulation to filtration and absorbent applications, making them an important component of the global economy.

Production process

The production of goods under HS code 6901 typically involves a multi-step process. First, the raw materials, such as kieselguhr or diatomite, are extracted and processed to remove impurities and achieve the desired particle size and purity. The processed materials are then mixed with binders and other additives, depending on the specific product being manufactured. The mixture is then formed into the desired shape, such as bricks, blocks, or tiles, using techniques like pressing, extrusion, or molding. Finally, the formed products undergo drying and firing at high temperatures to achieve the necessary strength, durability, and other properties.

Production inputs

The main inputs required for the production of goods under HS code 6901 include the raw materials, such as 2512 siliceous fossil meals, as well as various binders, additives, and processing equipment. The specific raw materials used can vary depending on the final product, but common sources include kieselguhr, tripolite, and diatomite. In addition, the production process may require specialized machinery for mixing, forming, drying, and firing the ceramic products.

Production outputs

The primary outputs of the industry covered by HS code 6901 are a wide range of ceramic goods, including bricks, blocks, tiles, and other products made from siliceous fossil meals or similar siliceous earths. These materials are widely used in the construction industry, as they offer excellent thermal and acoustic insulation properties, as well as resistance to chemical and physical wear. The outputs of this industry may also be used in various filtration and absorbent applications, as well as in the production of 6902 refractory bricks, blocks, tiles and similar refractory ceramic constructional goods.
