Products classified under HTS 6909.19.50.95
Porcelain Crucible for Laboratory Use
A high-purity porcelain crucible designed for melting and heating substances in chemical laboratories, fired after shaping to achieve low water absorption and high thermal resistance. It falls under HTS 6909.19.50.95 as ceramic ware specifically for laboratory and chemical uses, distinct from common tableware. The translucent body ensures precise observation during experiments.
Alumina Ceramic Evaporating Dish
A fired alumina-based ceramic dish used in labs for evaporating liquids and recovering precipitates during analytical chemistry processes. Classified under HTS 6909.19.50.95 for its technical laboratory application and high-temperature firing from inorganic nonmetallic materials. Its opaque, durable body withstands corrosive substances.
Ceramic Mullite Boat for Technical Furnaces
A mullite ceramic boat shaped and fired for holding samples in high-temperature technical furnaces during material testing and sintering. It qualifies for HTS 6909.19.50.95 as 'other technical uses' ceramic ware, made from siliceous clays and oxides. The design ensures stability under thermal cycling.
Zirconia Ceramic Mortar and Pestle Set
A lab-grade zirconia ceramic mortar and pestle fired for grinding and mixing chemicals without contamination. Under HTS 6909.19.50.95 for laboratory chemical uses, featuring high hardness from oxide-based nonmetallic materials. Naturally opaque and low-absorption for precise technical work.
Silicon Carbide Ceramic Filter Crucible
Fired silicon carbide ceramic crucible with integrated filter for separating solids in chemical filtration processes. Fits HTS 6909.19.50.95 as other laboratory/chemical use ware from high-melting-point carbides. Withstands aggressive acids and high temperatures.
