Prep-Free Packaging (PFP) / Over Boxing

Tier 3 of Amazon’s packaging pyramid is prep free packaging (PFP). These are products that cannot be shipped on their own and must be placed in an Amazon box or any product with a dimension less than the 9”x6”x0.375” minimum for SIOC packaging. This method is also referred to as over-boxing. The individual product packaging must still be ISTA 6 certified. Unlike FFP or SIOC, the PFP only offers vendors one benefit, which is a reduction or removal of Amazon Prep Chargebacks. 

To assist with assessing a product’s ability to withstand the shipping challenges of over boxing, Amazon partnered with ISTA to create the ISTA 6-Amazon.com-Over Boxing standard. This standard was written to test for e-commerce fulfillment for individual retail packaged-product weighing 70 pounds or less that are being placed in a larger container. It is common for Amazon.com to place these items into a larger shipping container with other individual retail packaged-products and then cushioned with dunnage (air pillows or Kraft paper). 

Amazon Over-Boxing challenges the products and its packaging to determine its ability to withstand the general damage-producing environment such as motions, forces and conditions of this transportation.
