Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If assembled into complete immersion water heater
Complete electric instantaneous or storage water heaters use heading 8516.10, not component resistors.
If installed in commercial kitchen equipment
Heating elements integral to industrial food machinery fall under Chapter 84 refrigeration/heating apparatus.
If open-wire resistors without protective sheath
Uninsulated composition or film-type resistors are specifically under 8545.90.
