Amazon SIPP (Ships in Product Packaging) Type C Package Testing

Amazon Type C packages encompass individual units exceeding 100 pounds, managed via conventional handling techniques. These items are integral to the Ships in Product Packaging (SIPP) initiative, allowing them to bypass additional Amazon boxing throughout the fulfillment sequence. This strategy eliminates the need for over-boxing, streamlining the distribution from origin to end-user.

ISTA 6 SIPP Type C Verification Process

The SIPP protocol’s objective is to mirror the real-world conditions a package might face within Amazon’s logistics framework, from its initial dispatch by the manufacturer or distributor through to delivery at an Amazon fulfillment center and onward to the consumer. This preemptive testing, crafted in partnership with the International Safe Transit Authority (ISTA) as the ISTA-6 Type C standard, is vital for preempting potential disruptions.

Amazon’s SIPP strategy is aligned with broader objectives to reduce waste, transport expenses, and lower return rates through the Frustration-Free Packaging (FFP) initiative. This program advocates for packaging that users can easily open, is predominantly made from recycled materials, and is optimized for minimal weight and size without necessitating additional Amazon preparation.

The verification program offers several advantages, including:

  • Lowered packaging expenses.
  • Minimized product damage, enhancing customer satisfaction and reducing returns.
  • Decreased or eliminated preparation fees.
  • Reduction or elimination of chargebacks.
  • Certification is a prerequisite for a significant number of Amazon’s vendors and sellers. Compliance involves submitting test outcomes via Seller Central, with vendor registration entailing comparable procedures.

Launching new products or packaging on Amazon.

  • Adjustments to product design.
  • Changes in Amazon’s packaging criteria necessitating reevaluation.
  • Noting damages during transit.

The rigorous testing process facilitates accelerated market access, equitable distribution costs, minimized product damage and losses, improved consumer satisfaction, and enhanced confidence in product introductions.

Criteria for Unacceptable Packaging

Amazon’s evaluation criteria for packaging underscore the importance of performance during testing.

Packages failing to meet standards due to non-taped, 123 or auto bottom designs, protrusions like tuck flaps, tabs, and handles, or cut-outs exposing the product are deemed non-compliant.

Additionally, the use of non-protective coverings, packaging that cannot sustain its form, or boxes lacking a conventional six-sided architecture will not pass.

Amazon SIPP Type C Pass/Fail Determinants

The pass/fail determinants for Type C packaging are established through collaborative efforts before testing, involving shippers, manufacturers, Amazon, and other relevant parties.

This collective process aims to define criteria for product damage, acceptable post-test packaging conditions, damage tolerance levels, and product condition assessment methods.
