Tier 3 of Amazon’s packaging pyramid is Prep Free Packaging (PFP). These are products that cannot be shipped on their own because of their size or packaging. Any package with dimensions smaller than those listed below must be shipped in an Amazon box. This method is also referred to as over-boxing. The individual product packaging must still be ISTA 6 certified. PFP is optional at this time for those small packages but they do still qualify for certification.
|NA||6” (152.4mm)||4” (101.6mm)||0.375” (9.5mm)|
|EU||8” (203.2mm)||4.72” (119.9mm)||0.375” (9.5mm)|
Unlike Frustration Free Packaging (“FFP”) or Ships In Own Container (“SIOC”), the PFP only offers vendors one benefit. This benefit is a reduction or removal of Amazon Prep Chargebacks.

Overboxing presents a number of unique challenges. To address these challenges, Amazon partnered with ISTA to create the ISTA 6-Amazon.com-Over Boxing standard. ISTA is the International Safe Transit Association and the authority on package testing standards.
This standard was written to test products 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. The products are then cushioned with dunnage (air pillows or Kraft paper).
Amazon Over-Boxing challenges the products and their packaging. The objective is to determine a package’s ability to withstand motions, forces and conditions of this transportation. The testing is completed by placing the test item, a hazard item and dunnage in a larger box. The hazard item is a block made of hardwood or metal. The block is .75 inches to one inch wide by six inches high. The length is at least eight inches longer than the second shortest package dimensions of the length, width and height. The long top edges of the block are rounded.
|Sequence Number||Test Category||Test Type||Test Level||For ISTA Certification|
TEST BLOCK 1
|Temperature and Humidity||Ambient||Required|
TEST BLOCK 1
|Controlled Temperature and Humidity||Temperature and Humidity chosen from chart||Optional|
TEST BLOCK 2
TEST BLOCK 3
|Random||Overall Grms levels of 0.53||Required|
TEST BLOCK 4
TEST BLOCK 5
|Leak Test||8 hours||Required for Liquids ONLY|
An analysis of the package and product is completed after testing. The acceptance criteria requires the product be fully functional in its intended use. If there are liquids, no leaks can be present. Any tamper-evident applications cannot be compromised. All seal integrity must be intact. All secondary packaging that is considered part of the product has no serious damage, scratches or indentations. It is important to note that the hazard products, dunnage or tertiary packaging are not to be considered in the acceptance criteria.
Most test types require one product sample to be tested. This must be a normal off-the-shelf product and not a golden unit. If the product is considered fragile, additional samples are required. Fragile items are defined as items that could easily break or could leak during the distribution process. Common examples of fragile items include glass, ceramic, porcelain and clay. Liquids include semi-liquids and solids that can become liquid at temperatures above 70 degrees Fahrenheit. Televisions and monitors are not considered fragile for testing purposes. However, these items have additional testing requirements. When multiple identical samples are tested, all samples must pass all tests.
