Hello, dshukla.
Please see the post I wrote concerning CE markings for coin cell batteries. The quantity can be found by searching for the ‘box’ icon in the price breaks section of a given part number, and can also be found at the bottom of most product pages in the “Additional Resources” section, entitled “Standard Package”.
Please note that simply ordering Standard Package quantity by itself is not sufficient to guarantee original manufacturer packaging, as our fulfillment team may arrange a 400-piece order from bits and pieces of available broken lots, instead. As directed in the original CE Markings post, this packaging must be actively requested at the time of placing the order, via the Order Notes section of your order.
