About HS Code 690320
This category covers refractory ceramic goods, other than bricks, blocks, or tiles, that contain more than 50% by weight of alumina (Al2O3) or a mixture/compound of alumina and silica (SiO2). These specialized articles are critical for specific high-temperature processes across various industries, including metallurgy, glass manufacturing, chemical processing, and advanced ceramics. Examples include crucibles, nozzles, tubes, kiln furniture, and other custom shapes designed for precise applications. They offer excellent refractoriness, chemical inertness, wear resistance, and thermal stability. Importers are diverse industrial sectors requiring specialized high-temperature components for their manufacturing lines. Exporters are countries with advanced ceramic manufacturing capabilities and access to high-purity alumina and silica. Their trade underscores the global reliance on precision ceramic components for demanding thermal applications.
