About HS Code 850640

This HS code covers primary (non-rechargeable) cells and batteries that utilize silver oxide chemistry. These batteries are highly valued for their high energy density, stable voltage output, and long shelf life, making them ideal for compact, high-performance applications where reliability is paramount. They are predominantly found in watches, calculators, small medical devices, and hearing aids. The international trade in silver oxide batteries is driven by the demand for reliable, miniature power sources for precision electronics. Importers and exporters include specialized battery manufacturers, watchmakers, and medical device companies, all seeking high-quality, long-lasting power solutions for their compact products.

Products Under This Code

SR44 silver oxide button cells, SR626SW watch batteries, 377 silver oxide batteries, hearing aid silver oxide batteries, calculator silver oxide batteries

Real World Examples
