Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If rare earth molybdates
Specific molybdate salts have separate provisions
If roasted molybdic concentrates
Mineral products before chemical processing
If sulfided active form
Sulfur compounds disqualify from wholly inorganic requirement

Import Tips & Compliance
• MoO3 content (15-20wt%) and CoO/MoO3 ratio specs verify hydrotreating grade
• Sulfidability test results confirm precursor functionality
• Alumina carrier purity affects classification if >50% composition
