Ceramic wares; for laboratory, chemical or other technical uses, other than articles having a hardness equivalent to 9 or more on the Mohs scale or of porcelain or china

HS code 690919 covers a wide range of ceramic products used in various industrial and scientific applications. These specialized ceramic wares are essential for industries such as chemistry, pharmaceuticals, and advanced manufacturing, where they are relied upon for their durability, chemical resistance, and thermal stability. As a key component in the global supply chain, the 690919 industry plays a vital role in supporting technological innovation and scientific research across numerous sectors.

The production of ceramic wares under HS code 690919 typically involves a multi-step process. Raw materials, including clay, feldspar, and other mineral additives, are carefully selected and blended to achieve the desired properties. The mixture is then shaped using techniques such as pressing, extrusion, or slip casting, depending on the specific product requirements. After shaping, the ceramic pieces undergo a drying and firing process, where they are exposed to high temperatures to achieve the necessary strength, density, and chemical resistance.

The main inputs required for the 690919 industry include a variety of raw materials, such as 2507 Kaolin and other kaolinic clays, 2529 Feldspar; leucite; nepheline and nepheline syenite, and other mineral additives. Additionally, specialized production equipment, such as kilns, presses, and molds, are essential for the manufacturing process. The industry also relies on a skilled workforce with expertise in ceramic engineering and materials science.

The ceramic wares produced under HS code 690919 are primarily used in laboratory, chemical, and other technical applications. These products may include beakers, crucibles, test tubes, and other specialized equipment used in scientific research and industrial processes. The output of this industry is often consumed by industries such as 3822 Diagnostic or laboratory reagents on a backing, prepared diagnostic or laboratory reagents whether or not on a backing, other than those of heading 30.02 or 30.06; certified reference materials, 8419 (Machinery, plant or laboratory equipment, whether or not electrically heated (excluding furnaces, ovens and other equipment of heading 85.14), for the treatment of materials by a process involving a change of temperature such as heating, cooking, roasting, distilling, rectifying, sterilising, pasteurising, steaming, drying, evaporating, vaporising, condensing or cooling, other than machinery or plant of a kind used for domestic purposes; instantaneous or storage water heaters, non-electric), and 9027 (Instruments and apparatus for physical or chemical analysis (for example, polarimeters, refractometers, spectrometers, gas or smoke analysis apparatus); instruments and apparatus for measuring or checking viscosity, porosity, expansion, surface tension or the like; instruments and apparatus for measuring or checking quantities of heat, sound or light (including exposure meters); microtomes).
