Can I Change Quantities on an Amazon Shipment Plan I Have Already Generated?

If you have already approved a shipment plan, Amazon FBA will only allow the quantity of each Amazon SKU to be edited up to 5%, or up to 6 units, above or below the original amount without incurring fees.

If you need to add more units, you will need to duplicate the shipment or create a new shipment.

You cannot add additional Amazon SKUs.
