1. I need help placing the product BARCODE and Amazon SHIPPING LABEL on the SAME BOX without a master box.

I have a product barcode GS1 US GTIN-12 (more commonly known as a UPC) and an Amazon FBA shipping label. There are 600 pcs products in 600 boxes without a master box.

Note: I have it set to use a manufacturer barcode (instead of an Amazon FNSKU barcode) for my listing.

On Google, I didn't find an exact answer to the question, “Where should the Amazon FBA shipping label and manufacturer barcode be placed on the outer box if there is no master box? Next to each other on the same side, or two different sides of the box?"

As far as I know, you must place both on the box, but we haven't done that before, so I need confirmation of the exact placement of the two labels on exactly which surface of the box !!

2. Should I use the master box if the size of one carton box averages 37* 9* 10 inches/95* 22* 24 cm and the gross weight is 13 Lbs/6 kg? If so, how many product boxes should be placed in a master box (and as an oversized item that exceeds 50.00 lb, indicating the "Team Lift" label on the top and sides of the master box)?

3. Also, please confirm that MY BARCODE GS1 US GTIN will be smoothly accepted in the US Amazon FBA system as a UPC INSTEAD of the Amazon FNSKU BARCODE.

I want my products to meet the Amazon FBA packaging requirements for packaging and prep standards.

Can anyone help? @Ricardo_Amazon, @Manny_Amazon, @Cooper_Amazon, @Steve_Amazon, or @Josh_Amazon

Thanks, and I appreciate it.
