Frequently Asked Questions: 

What types of tests are performed on my products? 

ISTA 6 Amazon.com – SIOC protocol is used for FFP (Tier 1) and SIOC (Tier 2). 
ISTA 6 Amazon.com – OB protocol is used for PFP (Tier 3). 

The test protocols involve many similar types of tests such as: 

Depending on the size of the packaged-product, there may also be additional tests required.  These include: 

If you are unsure which tests are applicable to your product Keystone Package Testing will assist you in making that determination. 

The major difference between SIOC and Over Boxing (OB) testing is that SIOC testing involves testing the packaged-product in its own packaging whereas OB testing involves placing the packaged-product in an over box filled with weighted hazard packages for testing.  Keystone Package Testing handles preparing your product in the over box for OB testing.  All you need to do is submit your packaged-products to us. 

How many samples are required for testing? 

For SIOC testing:
1 sample is required for non-fragile and non-liquid products 
5 samples are required for fragile or liquid products 


For OB testing:
2 samples are required for non-fragile and non-liquid products 
5 samples are required for fragile or liquid products 

Do I need to test every ASIN for products that are similar? 

Depending on the circumstances, some products can be certified based on test results of similar products that are already certified.  Please contact us to discuss your particular situation. 

Are there any size limitations for SIOC or FFP packages? 

Yes, Packages must be a minimum of 9”x6”x0.375” to be certified as a FFP or SIOC package.  Boxes with any dimension smaller than those listed are too small to travel through Amazon’s conveyance system and must be certified and shipped as an Overbox. 

What constitutes a package passing or failing? 

There are two categories of failures: Objective Failures and Customer-Focused Failures. 

Objective failures are events such as damage, breakage, loss of function, loss of use, collectible items with outer package wear, seal integrity compromise or the tamper evident application is compromised. Objective Failures will be determined by Keystone Package Testing. 

A Customer-Focused Failure occurs when a package meets the objective requirements but has deficiencies that might lead a customer to not accept the package. These deficiencies can include events such as wear, denting or scuffs on the outer package or small/minor dents on the primary form factor. The vendor has the final decision-making authority as to whether or not a deficiency qualifies as a Customer Failure. 

What are the benefits of certifying packages? 

  • For Tier 1 (FFP), Tier 2 (SIOC) or Tier 3 (PFP), certification removes the prep flag at an Amazon Standard Identification Numbers (ASIN) – Vendor Level (Need correct vendor code you ship on).
  • For Tier 1 (FFP) or Tier 2 (SIOC), certification removes packaging instructions and sets the ASIN to “Ships in Own Container”.
  • For Tier 1 (FFP), certification adds detail page messaging, qualifies for Vine Credits and the products will receive additional search relevancy for FFP promotion days.
