Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If alkali-free
Alkali-free silver oxide cells fall under a separate subheading regardless of volume, changing the classification due to electrolyte composition.
If volume exceeds 300 cm³
Larger silver oxide primary cells without volume restriction go to the general mercuric oxide subheading, based on size threshold.
If imported as parts or components
Unassembled battery components or incomplete cells are classified as parts of primary cells rather than complete batteries.
