About HS Code 850630

This category covers primary (non-rechargeable) cells and batteries that use mercuric oxide. Historically, these batteries were valued for their stable voltage output and long operational life, making them suitable for applications such as hearing aids, medical devices, and photographic equipment. However, due to significant environmental concerns regarding their mercury content, the production and international trade of mercuric oxide batteries have drastically declined and are heavily restricted or banned in many countries. Any remaining trade is highly specialized, often for legacy equipment or specific industrial applications where no suitable mercury-free alternative exists, making this a niche and diminishing market.

Products Under This Code

Mercuric oxide button cells, mercury batteries for vintage cameras, specialized medical device mercury batteries

Real World Examples

PX625 mercury battery (vintage cameras), MR9 mercury battery (vintage cameras), specific hearing aid mercury batteries (largely phased out)

Common Misclassification

Highly likely to be confused with other primary button cells like 850640 (silver oxide) or 850650 (lithium) due to similar form factor. The key differentiator is the mercuric oxide chemistry, which is now rare and restricted.
