In the Shipment Creation Workflow, the Fulfillment by Amazon team displays preparation guidance for products you are about to ship to Amazon on the “Prepare Products” tab. You will see the word “Investigate” in the Prep guidance column. You can click “Investigate” to open the prep investigation tool.
Submitting a prep investigation request
While creating your shipment in Seller Central, you will be shown guidance on how to prep your products before shipping them to Amazon fulfillment centers. If you decide to investigate this prep guidance further, follow these steps:
Review current prep classification: Each of your products has one or more specific attributes that determine what level of prep is needed. We group these attributes into classifications that dictate exactly what type of prep is needed for a given product. Before you submit an investigation request, you must first review your product’s current classifications to see if you think one or more are accurate.
Submit a request: If you feel the prep classifications are all inaccurate, you can submit an investigation request. Next, you will be asked to give more details and review a brief video about FBA prep.
Wait three days for the response: Once your submission is complete, we will create a case for the request and you will receive an e-mail to confirm your submission. A response will be provided within three business days.
Note: After a prep investigation request has been submitted, another request cannot be made for 90 days. If a review is required due to additional information you may have, please re-open the case found in your Case Log.
