About refractory cements, mortars, concretes and similar compositions, including dolomite ramming mix, other than products of heading 38.01

HS code 3816 covers a range of refractory materials used in high-temperature applications, such as the production of steel, glass, and ceramics. These specialized cements, mortars, and concretes are essential for the construction and maintenance of industrial furnaces, kilns, and other heat-intensive equipment. As a key component of many manufacturing processes, the 3816 industry plays a vital role in supporting the broader economy.

Production process

Refractory materials under HS code 3816 are typically produced through a combination of mixing, molding, and firing processes. Raw materials, such as clay, silica, and alumina, are carefully selected and blended to achieve the desired chemical and physical properties. The mixture is then shaped into the required forms, such as bricks or castable shapes, and subjected to high-temperature firing to enhance its heat resistance and structural integrity.

Production inputs

The main inputs for the 3816 industry include a variety of raw minerals and materials, such as 2507 Kaolin and other kaolinic clays, 2508 Other clays, andalusite, kyanite and sillimanite, whether or not calcined; mullite; chamotte or dinas earths, 2510 Natural calcium phosphates, natural aluminium calcium phosphates and phosphatic chalk, and 2522 Quicklime, slaked lime and hydraulic lime. Additionally, specialized equipment, such as high-temperature kilns and mixing machinery, are essential for the production of these refractory materials.

Production outputs

The primary outputs of the 3816 industry are refractory cements, mortars, concretes, and similar compositions, which are used in a wide range of industries. These materials are often consumed by manufacturers of 6901 Bricks, blocks, tiles and other ceramic goods of siliceous fossil meals or of similar siliceous earths, 6902 Refractory bricks, blocks, tiles and similar refractory ceramic constructional goods, other than those of siliceous fossil meals or similar siliceous earths, and 6903 Other refractory ceramic goods, e.g. retorts, crucibles, muffles, nozzles, plugs, supports, cupels, tubes, pipes, sheaths and rods, other than those of siliceous fossil meals or of similar siliceous earths.
