Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the molybdenum oxide contains more than 15% phosphorus by weight
Chapter note 7 classifies copper phosphide with high phosphorus in heading 28.53, and similar logic may apply to other metal oxides with high phosphorus content.

Import Tips & Compliance
• > Ensure the product is clearly identified as a mixture of MoO2 and MoO3 with a certificate of analysis
• Declare the exact chemical composition to avoid reclassification
• If the product contains more than 15% phosphorus, it may fall under heading 28.53 instead
