Please select Yes or No. So, we can identify if we will prepare the items as multipack before sending them to customers or Amazon.
UPC Guidelines for multi-packs
As a general rule, each unique product manufactured and sold to consumers must have a unique trade item number (UPC, EAN, ISBN, or GTIN). An item sold singly is a different " sellable unit " from a pack (or set) including multiples of that same item. Each sellable unit defines a separate product that must have its own product identifier, usually a UPC.
This section contains guidelines for listing multi-pack products. In most Amazon categories, sellers are required to use a separate UPC for multi-pack products, and they must also indicate the "item package quantity" when listing multi-packs.
