Step 3 - Prepare the items for shipping

To prepare your items for shipping, do the following:
  1. Make sure each item that you are shipping conforms to Amazon's product packaging requirements.
  2. Group the items into separate shipments, one for each shipment in the shipment plan that was returned when you called the CreateInboundShipmentPlan operation.
  3. If you are sending items that require item labels, create and apply the item labels.
    For more information about creating item labels, see Item label specifications.

    For more information about when items require item labels, see Step 2 - Create an inbound shipment plan.
