HS Code for Molybdenum oxide

Molybdenum oxides and hydroxides are classified under HS code 2825.70. Chapter 28 covers inorganic chemicals, including precious metal compounds, radioactive elements, and isotopes. Heading 2825 specifically includes hydrazine and hydroxylamine and their inorganic salts, as well as other inorganic bases and metal oxides, hydroxides, and peroxides. Molybdenum trioxide (MoO3) and molybdenum dioxide (MoO2) are the primary products under this code. To be classified here, the product must generally be a separate chemically defined compound, distinguishing it from the crude roasted concentrates found in Chapter 26. These oxides are essential in the production of molybdenum metal, catalysts, and pigments.

Products Included

• Molybdenum trioxide (pure or chemical grade)
• Molybdenum dioxide
• Molybdic acid and molybdenum hydroxides
• High-purity molybdenum oxides for catalyst production

Common Misclassification

A frequent point of confusion exists between HS code 2825.70 and HS code 2613.10. Code 2613.10 covers roasted molybdenum concentrates, which are sometimes commercially called "molybdenum oxide." However, if the product is a crude concentrate obtained by roasting the ore, it belongs in 2613.10. Only when it is further refined into a specific chemical compound does it move to 2825.70. Additionally, molybdates (salts of molybdic acid) should be classified under 2841.70 rather than 2825.70.

FAQ

What is the HS code for molybdenum oxide?

The HS code for chemically defined molybdenum oxides and hydroxides is 2825.70.

Is technical grade MoO3 classified here?

It depends on the purity and processing. If it is a refined chemical compound, it is 2825.70. If it is simply roasted ore concentrate, it is 2613.10.
