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 valued for their unique properties, including high porosity, low thermal conductivity, and chemical inertness. The products within this code play a crucial role in various industries, from construction and filtration to insulation and absorbents, making them an important part of the broader economy.

The production of goods under HS code 690100 typically involves mining and processing the raw siliceous materials, followed by forming, drying, and firing the ceramic products. The specific techniques may vary depending on the final product, but often include milling, pressing, and high-temperature firing to achieve the desired properties and durability.

The main inputs required for the production of goods under HS code 690100 include the raw siliceous materials, such as 2512.00 (Siliceous fossil meals (for example, kieselguhr, tripolite and diatomite) and similar siliceous earths), as well as energy sources for the firing process, such as natural gas or electricity. Specialized machinery for mining, processing, and forming the ceramic products is also a critical input.

The outputs of the industry covered by HS code 690100 include a wide range of ceramic goods, such as bricks, blocks, tiles, and other specialized products. These materials are often used in construction, filtration, and insulation applications, and may be consumed by industries covered by codes such as 6901.00 (Bricks, blocks, tiles and other ceramic goods of siliceous fossil meals (for example, kieselguhr, tripolite or diatomite) or of similar siliceous earths), 6902.10 Refractory bricks, blocks, tiles and similar refractory ceramic constructional goods, other than those of siliceous fossil meals or similar siliceous earths, and 6914.90 Other ceramic articles, among others.
