5. You will now need to decide who will place your FNSKU labels on your products. There’s two options, Amazon can barcode your items once they receive your shipment at the fulfilment centre although there is a fee for this service.  Otherwise, if you have a printer or even better a thermal printer such as a Dymo LabelWriter 4XL you can do it yourself and it’s a very straightforward process.

If you want Amazon to label your products, you select ‘Amazon’ from the ‘Who prepares’ dropdown menu otherwise you select ‘Seller’.

Note: if your manufacture has already printed the FNSKU labels directly onto your product’s packaging you don’t need to perform this step just select ‘Seller’ from the dropdown menu and move onto the next step.

Recommended Packaging Products for FBA Shipments


You will need heavy duty postal scales to weigh your boxes that you’re shipping into Amazon’s fulfilment centre. Ensure the scales are capable of weighing items up to 50kg at least (see recomended scales).

Thermal Printer

Thermal printers are perfect for printing FNSKU’s and postage labels as they have fast print speeds. Not only do they not use ink, they have less moving parts so they are less likely to go wrong. The Dymo LabelWritter 4XL is a great one to use.

Bubble wrap & Air Packing Pillows

Bubble wrap is great to protect fragile items. Air packing pillows is also perfect to fill space in boxes and leaving your items cushioned and protected. You don’t want to be finding out once your products have reached the warehouse that they have been damaged in transit and you won’t be compensated as it’s your fault.

Packing Tape

If you’re shipping heavy items make sure you use strong packaging tape, you don’t want your boxes to break while in transit.

Suffocation Labels

If your product comes in a poly-bag and if the size is greater than 5 inches you will need to have suffocation warning labels on the bags. These can be printed directly onto the bag or can be placed as labels (see suffocation labels). The print size of these labels depend on the width of the bag (see below).

In order to send your shipment into Amazon you need to use carton boxes, you cannot use mailing bags or envelopes. You can re-use boxes but ensure if there any old barcodes visible on the boxes these will need to be covered up. For fragile items, it is advisable to use double-walled boxes.

11 Tips for Sending Your Inventory into Amazon

1. Before sticking any FNSKU labels on your products ensure they are readable.You can download a free barcode reader on your smartphone and you can use this to test if the barcodes are readable.

2. Always place the FNSKU label over the UPC code on your product packaging. Never leave the UPC code uncovered.

3. In order to save time, it’s advisable to ask your manufacture to print the FNSKU labels directly onto your products packaging. This way you don’t need to bother printing separate FNSKU labels which should save you time and effort.

4. Use a thermal printer to print your FNSKU labels as they don’t use ink which means your labels won’t fade at Amazon’s fulfilment centre.

5. Always ensure every product is barcoded. If you miss a product, it could delay the receiving process. Amazon may also charge if they need to add new barcodes or resolve any issues.

6. When weighing your boxes always round up otherwise you may be charged extra if the weight you have quoted is not valid.

7. Poly-bagged units must carry a suffocation warning label if the opening is 5 inches or larger. The suffocation label can be printed directly onto the poly-bag or attached as a label.

8. If you’re selling items as a set, you will need to indicate this clearly i.e. add a label with the following ‘This is a set. Do not separate’.

9. Ensure shipping labels are not placed over the seam of the shipping box, make sure the two shipping labels are placed either side of the seam.

10. If your product requires an expiry date, make sure it’s in the following format: MM-DD-YYYY.

11. Depending on what you’re shipping, Amazon will have different requirements for some products. It’s best to check Amazon’s site to see if you need to do anything special.
