Amazon’s FBA program has strict regulations for the condition of shipments and products. Every product that is intended for sale on Amazon must have an “FNSKU” label and a “Made in” label. The FNSKU label is necessary for Amazon to identify a particular unit of an ASIN, and it should be visible on all products. If there is more than one product under a single FNSKU, a “Do Not Separate” label is required. Products lacking these labels may be disposed of, sold separately, or removed from Amazon FBA at your expense.
