Yes. You can use the FBA Inbound Pickup Service even when you are shipping directly from the manufacturer or supplier. All you need is the shipment details while creating the shipment in Seller Central. For example, if you want to use the FBA Inbound Pickup Service, you need to know the number of boxes, weight and dimension of each box to be able to calculate the rate and print shipping labels. Once you print the labels, you need to send those labels to your manufacturer/supplier. Please also make sure to enter the manufacturer’s address as the "Ship From" location.
