About ceramic goods; (e.g. retorts, crucibles, muffles, nozzles, plugs, supports cupels, tubes, pipes, sheaths, rods and slide gates) excluding those of siliceous fossil meals or of similar siliceous earths

HS code 6903 covers a diverse range of ceramic goods, including retorts, crucibles, muffles, nozzles, plugs, supports, cupels, tubes, pipes, sheaths, rods, and slide gates. These specialized ceramic products play a crucial role in various industrial processes, from metallurgy and chemical production to high-temperature applications. The global demand for these ceramic goods is driven by the need for durable, heat-resistant, and chemically inert materials in a wide array of industries, making this code an important component of the broader industrial supply chain.

Production process

The production of ceramic goods under HS code 6903 typically involves a multi-step process. First, the raw materials, such as clay, feldspar, and other mineral additives, are carefully selected and mixed to achieve the desired composition and properties. The mixture is then shaped using various techniques, such as pressing, extrusion, or casting, depending on the specific product. After shaping, the ceramic pieces undergo a high-temperature firing process, which fuses the materials and imparts the desired strength, durability, and heat resistance. Finally, the finished products may undergo additional finishing steps, such as polishing or glazing, to meet specific requirements.

Production inputs

The main inputs required for the production of ceramic goods under HS code 6903 include a variety of raw materials, such as 2507 Clays and 2529 Feldspar, as well as other mineral additives. Specialized equipment, such as kilns, presses, and extrusion machines, are also essential for the manufacturing process. Additionally, the industry relies on skilled labor, technical expertise, and energy resources to ensure efficient and high-quality production.

Production outputs

The ceramic goods produced under HS code 6903 are used in a wide range of industrial applications, including 8401 Nuclear reactors, 8402 Steam or other vapour generating boilers, and 8403 Central heating boilers. These ceramic products are valued for their ability to withstand high temperatures, corrosive environments, and mechanical stress, making them indispensable in various manufacturing and processing industries. The outputs of this industry may also be consumed by other HS codes, such as 6901 Bricks, blocks, tiles and other ceramic goods of siliceous fossil meals or of similar siliceous earths and 6902 Refractory bricks, blocks, tiles and similar refractory ceramic constructional goods, other than those of siliceous fossil meals or similar siliceous earths.
