HS Code for Zirconium dioxide
Zirconium dioxide (ZrO2), also known as zirconia, is classified under HS code 282560 because it is a chemically defined inorganic compound. Chapter 28 of the HS nomenclature is dedicated to inorganic chemicals, and heading 2825 specifically covers hydrazine and hydroxylamine and their inorganic salts, as well as other inorganic bases and other metal oxides, hydroxides, and peroxides. Within this heading, subheading 2825.60 is the specific provision for germanium oxides and zirconium dioxide. To fall under this code, the product must be a separate chemically defined element or compound, as per Note 1 to Chapter 28. This means that naturally occurring zirconium minerals, such as zircon (zirconium silicate) or baddeleyite (natural zirconium oxide), are generally excluded from this chapter and are instead classified in Chapter 26 (Ores) or Chapter 25 (Earth and stone). The classification 282560 is reserved for the oxide obtained through chemical processing, such as the calcination of zirconium hydroxides or the treatment of zircon sand with reagents. It is a high-purity industrial chemical used in the production of advanced ceramics, oxygen sensors, and as a precursor to other zirconium chemicals.
Products Included

Common Misclassification
Zirconium dioxide is often misclassified under HS code 261510, which is for zirconium ores and concentrates like zircon sand. It may also be confused with 253090 if mistaken for a crude mineral substance. Additionally, if the zirconia is mixed with binders for use as a prepared ceramic paste, it may fall under 382499.
