About HS Code 690100
This HS code specifically covers bricks, blocks, tiles, and other ceramic goods manufactured from siliceous fossil meals, such as kieselguhr, tripolite, or diatomite, or similar siliceous earths. These materials are characterized by their lightweight, porous structure and excellent thermal insulating properties, making them ideal for high-temperature applications where energy efficiency is critical. They are primarily used as insulating firebricks in industrial furnaces, kilns, boilers, and other thermal processing equipment across sectors like metallurgy, glass, and ceramics. Importers are typically industries requiring efficient thermal management and insulation solutions. Exporters are countries with natural deposits of these siliceous earths and the manufacturing expertise to produce these specialized ceramic goods. Key features include their low thermal conductivity, high porosity, and relatively low density compared to other refractory materials.
Products Under This Code
