8506 - Primary cells and primary batteries; parts thereof:

HTS code 8506 encompasses primary cells and primary batteries, as well as their parts. This category specifically covers devices that generate electrical energy through an irreversible chemical reaction, meaning they cannot be recharged once depleted. Examples include common alkaline, zinc-carbon, and lithium primary batteries used in a wide array of consumer electronics, portable devices, and specialized equipment.

Distinguishing this category from its siblings involves understanding that HTS 8506 is focused solely on non-rechargeable (primary) power sources. Other categories within Section XVI and Chapter 85 deal with a broad spectrum of electrical machinery, equipment, and components, including secondary (rechargeable) batteries, electrical generators, motors, and various electrical apparatus, none of which fall under the purview of primary cells and batteries.

Within HTS 8506, further classification is based on the specific type of chemistry or material used in the primary cell or battery. Subcategories differentiate based on active materials such as manganese dioxide, mercuric oxide, silver oxide, and lithium. Additionally, a specific subcategory exists for air-zinc batteries, while "Other primary cells and primary batteries" captures those not specifically enumerated. The "Parts" subcategory is for components dedicated to the manufacture or repair of these primary cells and batteries.
