Before sellers send in any perishable items to an Amazon fulfilment centre they must flag the item on their Seller Central account prior to creating a shipment. All sellers must:
Download the FBA Fulfilment Attributes template*. In this Excel sheet, you will need to complete the tab titled "Template." You can use the tab "Example" to see how the form should be filled in. In column A, enter the FBA SKUs which contain an expiry date. In Column B, select "TRUE." Columns E to H require the dimensions of the product as well as the unit of measure (column H). You must fill in all columns.
As with most Amazon Flat files, once they are complete they must be saved as "text (tab-delimited)" documents before uploading. To upload the file on your Seller Central account, select Add products via Upload under your Inventory tab. In the drop-down menu, select Inventory Files for Non-Media Categories, then locate your file by selecting Browse > Choose File before selecting Download Template.
The file can take up to 45 minutes to upload. Once complete you can then convert your listings to FBA and continue working on your shipment.
* FBA Fulfilment Attributes template can also be used to enter product dimensions in bulk. For more information, see How to List FBA Products in Bulk with Flat File Feeds.
