Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If chemically produced unwrought molybdenum
Unwrought molybdenum metal derived from oxides falls under Chapter 81 as base metals, not oxides.
If used as inorganic pigment
Chapter note excludes luminophores or pigments from Chapter 28; classified in 3206 if prepared for pigment use.
If doped for electronics in worked form
Doped molybdenum compounds in disc/wafer forms shift to 3818 per Chapter note on electronic materials.

Import Tips & Compliance
• Provide assay reports showing >99% MoO2 content to avoid reclassification; check for REACH-like certifications if from EU
• Pitfall: confusing with sintered forms which may go to Chapter 81
