Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If waste or spent condition
Spent primary cells incapable of use classify under 8549.11 per chapter notes, but 8501 for other waste.
If same chemistry but larger size
Mercuric oxide cells over 300 cm³ have separate subheading with different duty treatment.
If battery imitation without active chemistry
Non-functional display batteries classify as plastic articles, not electrical cells.
