Use HS-6 850640 when importing or exporting primary silver oxide batteries. These batteries are commonly used in watches, hearing aids, and small electronic devices. For instance, a shipment of silver oxide batteries for a watch manufacturer would fall under this code.
This code specifically applies to silver oxide batteries, distinguishing them from other primary batteries like alkaline or lithium types, which are classified under different HS codes such as 850610 or 850680. Understanding these distinctions is crucial for accurate customs declarations.
Silver oxide batteries are known for their stable voltage and high energy density, making them ideal for precision instruments. If you're dealing with batteries that are not silver oxide, like zinc-air batteries, you will need to refer to a different classification, such as 850680.
When preparing your shipment, ensure that the packaging clearly identifies the batteries as silver oxide, as this will help avoid classification errors during customs clearance.
