This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified as germanium hydroxide rather than oxide
Hydrated forms exceeding certain water content may be hydroxides.
If forming complex salts with metals
Chapter notes specify metal salt complexes go to heading 2842.
If containing significant vanadate impurities
Mixed metal oxides with vanadium classify under specific vanadates.

Import Tips & Compliance
• Thermogravimetric analysis (TGA) proving hydrate decomposition to pure GeO2 required
• Label precisely as 'germanium dioxide monohydrate' avoiding generic 'oxide hydrate' terms
• Distinguish from germanium hydroxides which may classify differently
