Prime Freight suggests that your manufacturer sign cartons with the following information:

Brand Name: (name of your brand)

Product SKU: (product SKU)

Country of Origin: (e.g. China)

Gross Weight: (weight of carton, including packaging)

Net Weight: (weight of goods without packaging)

Carton Dimensions: (length X width X height)

Carton Series Count: (X of X)

Prime Freight recommends that your suppliers label the cartons with the FBA label if you ship to an Amazon FBA warehouse. But if the cartons can not be marked by your supplier, the cartons must be marked by the Amazon SKU (FNSKU).
