Amazon Package Testing - APASS


The rapid, worldwide acceptance of e-Commerce has been partially enabled through properly designed and tested products and packaging thereby ensuring the customer’s order arrives at its ultimate destination working and undamaged. Be assured none of this happened by chance. Several years ago, the packaging engineers at Amazon and the International Safe Transit Association (ISTA) created the ISTA 6-Amazon protocols which define the simulation tests required by Amazon’s e-Commerce fulfillment program.

WESTPAK is listed on the Amazon Packaging Support and Supplier Network (APASS) as a Packaging Testing firm supporting vendors, sellers, and manufacturers who must certify their products as Amazon Prep-Free Packaging (PFP), Ships-In-Own-Container (SIOC), and Frustration-Free Packaging (FFP).

WESTPAK has been approved by Amazon to test and certify products as PFP, SIOC, or FFP. Certification requires products be evaluated to meet all requirements for the corresponding standards listed in the Packaging Certification Guidelines, pass the ISTA 6 SIOC test (FFP/SIOC), or the ISTA 6 Overbox (PFP) test using ISTA certified testing equipment.
