Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If incorporated into ready-to-use marine paints
Paints and varnishes based on polymers with cuprous oxide as pigment are classified in Chapter 32 under 3208.
If precious metal compounds are present
Chapter notes exclude certain complex compounds; those with precious metals go to 2843.
If for supported catalysts containing cuprous oxide
Cuprous oxide used as a catalyst supported on inert material falls under 3815, not pure oxides.

Import Tips & Compliance
• Provide end-use statements if destined for marine applications to preempt EPA pesticide classification reviews
• Ensure packaging prevents oxidation; declare as 'cuprous oxide, technical grade' on commercial invoice
• Comply with US Coast Guard regulations for antifouling biocides during import clearance
