Products classified under HTS 2825.60.00
Zirconium Dioxide Powder (ZrO2)
High-purity zirconium dioxide powder used in ceramics and refractories. Classified under HTS 2825.60.00 as it is a chemically defined inorganic metal oxide of zirconium.
Germanium Dioxide (GeO2) Crystals
Synthetic germanium dioxide crystals used in fiber optics production. Falls under HTS 2825.60.00 as a chemically defined germanium oxide per Chapter 28 notes.
Zirconia Nanopowder (ZrO2 99.9% Pure)
Ultrafine zirconium dioxide nanopowder for advanced coatings and fuel cells. Classified in 2825.60.00 as pure germanium/zirconium dioxide regardless of particle size.
High-Purity Germanium(IV) Oxide
Laboratory-grade GeO2 used in optical glass manufacturing. HTS 2825.60.00 covers chemically defined germanium oxides meeting Chapter 28 Note 1 criteria.
Stabilized Zirconium Dioxide (YSZ)
Yttria-stabilized zirconia powder for solid oxide fuel cells. Still classifies under 2825.60.00 as primary zirconium dioxide component per metal oxide headings.
Germanium Dioxide Hydrate (GeO2·H2O)
Hydrated form of germanium dioxide used in chemical synthesis. HTS 2825.60.00 includes germanium oxides in all hydration states as chemically defined compounds.
Monoclinic Zirconia Powder
Monoclinic crystal structure ZrO2 powder for dental applications. Pure zirconium dioxide classifies under 2825.60.00 per metal oxides subchapter.
Technical Grade Zirconium Dioxide
Industrial ZrO2 powder from zircon sand for refractories. Meets chemically defined criteria of HTS 2825.60.00 despite lower purity vs electronic grades.
Amorphous Germanium Dioxide Glass
Vitreous GeO2 used in specialty optical fibers. Still pure germanium oxide under HTS 2825.60.00; glass form doesn't change chemical classification.
Yttria Partially Stabilized Zirconia (8YSZ)
8 mol% yttria-doped ZrO2 thermal barrier coating powder. Primary component remains zirconium dioxide for HTS 2825.60.00 classification.
Electronic Grade Germanium Dioxide
Ultra-high purity GeO2 for semiconductor doping sources. Meets stringent Chapter 28 chemical definition for HTS 2825.60.00 classification.
Zirconium Dioxide for Jewelry
Synthetic cubic zirconia precursor powder for gemstone production. Raw oxide form remains HTS 2825.60.00 before crystal growth processing.
Calcined Zirconia from Zircon
Thermal plasma dissociated ZrO2 from zircon feedstock. Chemically defined zirconium dioxide qualifies for HTS 2825.60.00 post-calcination.
Germanium Oxide Sputtering Target Material
GeO2 powder for thin film deposition targets. Pure oxide powder form before target fabrication stays in HTS 2825.60.00 chemical classification.
Medical Grade Zirconia Powder
Biocompatible ZrO2 for orthopedic implants and dental prosthetics. High medical purity but remains zirconium dioxide under HTS 2825.60.00.
