Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the batteries are imported for use in the manufacture of smoke detectors
This sibling tariff item offers a reduced or different duty treatment for batteries destined specifically for smoke detector production.
If the battery were lithium-based rather than silver oxide
Lithium primary cells are classified separately under heading 8506, and this alternative would apply if the chemistry changed.
