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

Amazon has introduced the Type D package testing protocol, tailored for Less Than Truckload (LTL) shipments that weigh under 100 pounds. LTL shipments refer to those not typically handled by conventional parcel delivery services such as Amazon, UPS, FedEx, or the US Postal Service.

Despite their LTL classification, these packages are processed using standard handling procedures.

The Ships in Product Packaging (SIPP) standard is tailored for products shipped in their retail packaging, eliminating extra Amazon boxing and over-boxing. SIPP packages must endure the entire Amazon fulfillment process, from origin to the final customer.

ISTA 6 SIPP Type D Verification Process

For Amazon vendors and sellers, undergoing package verification is often mandatory. This process requires the submission of package testing data via Amazon Seller Central, including a comprehensive test report from an Amazon-certified packaging test laboratory.

Laboratories receive certification through Amazon’s APASS (Amazon Packaging Support and Supplier Network), ensuring they possess a thorough understanding of Amazon’s fulfillment packaging guidelines. Additionally, the Amazon vendor enrollment protocol often includes package certification. This requires the use of predominantly recycled materials, ease of opening, and minimizing added weight or dimensions, in line with Amazon’s Frustration-Free Packaging (FFP) initiative.

Engaging in the package testing process affords sellers and vendors numerous advantages, including expedited market entry, optimized distribution costs, diminished product damage and loss, heightened customer satisfaction, and bolstered confidence in product launches.

Criteria for Unacceptable Packaging

For a package to be eligible for certification, it must adhere to specific standards:

  • Packages must be durable, six-sided rectangular boxes.
  • All openings must be securely sealed to maintain integrity during shipment, excluding the use of staples for sealing, although they may be employed on the manufacturer’s glue joint.
  • Any locking tabs should be secured with tape or adhesive.
  • Labels and markings on the package must unambiguously indicate the contents and any special handling instructions required.
  • Consideration should be given to the product-to-package ratio, or the total cubic volume occupied by the primary product and its essential components.

Amazon SIPP Type D Pass/Fail Determinants

Amazon delineates precise pass/fail standards for its SIPP program prior to testing. This preparatory phase is a collaborative effort among shippers, manufacturers, Amazon, and additional stakeholders, focused on safeguarding both product and packaging integrity. Key considerations include:

Defining Product Damage: Clarifying the criteria for unacceptable product damage post-shipment.

Package Condition Post-Testing: Determining the acceptable level of wear and tear on the package from transit.

Damage Tolerance: Establishing the thresholds for permissible damage during shipment.

Product Condition Evaluation: Consensus on methods for assessing the condition of the product upon receipt.

These standards are integral to upholding Amazon’s commitment to customer satisfaction, minimizing transit damage, and advocating for environmentally responsible packaging solutions, thereby ensuring a flawless delivery experience.

Overview of the ISTA-6 Type D Test Plan

The testing protocol for Amazon Type D products is a collaboration between Amazon and ISTA (International Safe Transit Authority), officially named ISTA-6 Type D.
