HS v2022 Code: 690220

About refractory bricks, blocks, tiles and similar refractory ceramic constructional goods; containing by weight more than 50% of alumina (al2o3), of silica (sio2) or of a mixture or compound of these

HS code 690220 covers a range of refractory ceramic construction materials, including bricks, blocks, tiles, and other goods. These products are essential for industries that require high-temperature resistance, such as steel production, glass manufacturing, and cement kilns. The global refractory market is a significant component of the broader construction and industrial sectors, with a growing demand driven by infrastructure development and the need for energy-efficient, durable building materials.

Production process

The production of refractory ceramic goods under HS code 690220 typically involves a multi-step process. Raw materials, such as alumina, silica, and various mineral additives, are carefully selected and blended to achieve the desired chemical composition and physical properties. The mixture is then formed into the desired shape, often through pressing or extrusion, and subjected to high-temperature firing or sintering to enhance its strength, density, and heat resistance.

Production inputs

The main inputs for the production of HS code 690220 goods include raw materials like alumina, silica, and other refractory minerals. Specialized machinery, such as kilns, presses, and extruders, are also essential for the manufacturing process. Additionally, energy sources, such as natural gas or electricity, are required to power the high-temperature firing and sintering stages.

Production outputs

The primary outputs of HS code 690220 are refractory bricks, blocks, tiles, and other construction materials that are highly resistant to heat, corrosion, and abrasion. These products are widely used in the construction of industrial furnaces, kilns, and other high-temperature equipment found in 731000 Iron and steel industry, 700000 Glass industry, and 252300 Cement industry.
