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

HS code 690100 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 prized for their unique properties, including high porosity, low density, and excellent insulating capabilities. The products classified under this code are widely used in a variety of industries, from construction and filtration to absorbents and specialty applications, making it an important segment of the broader ceramic goods market.

The production of goods under HS code 690100 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 combined with binders and other additives, depending on the specific product being manufactured. The mixture is then shaped, either through molding, extrusion, or other forming techniques, and subsequently dried and fired at high temperatures to achieve the desired hardness, strength, and other physical properties.

The main inputs required for the production of goods under HS code 690100 include the siliceous fossil meals, such as [nc_link(2512)](Siliceous Fossil Meals And Similar Siliceous Earths), as well as various binders, additives, and specialized machinery for shaping, drying, and firing the ceramic products. The availability and quality of these raw materials, as well as the efficiency of the production equipment, are critical factors in determining the overall competitiveness and performance of this industry.

The primary outputs of the industry covered by HS code 690100 are a wide range of ceramic goods, including bricks, blocks, tiles, and other specialized products. These materials are widely used in the construction industry, as well as in various filtration, absorbent, and specialty applications. The outputs of this industry may be consumed by industries classified under codes such as [nc_link(6901)](Ceramic Bricks, Blocks, Tiles And Other Ceramic Goods), [nc_link(8421)](Centrifuges, Filtering Or Purifying Machinery And Apparatus, For Liquids Or Gases), and [nc_link(3824)](Prepared Binders For Foundry Moulds Or Cores; Chemical Products And Preparations Of The Chemical Or Allied Industries).
