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

The Amazon SIPP (Ships in Product Packaging) Type B package certification is of paramount importance for vendors and sellers aiming to streamline their delivery process. For packages to qualify for the Type B testing method, they must weigh between 50 and 100 pounds and maintain a girth not exceeding 165 inches. Typically dispatched via standard shipping methods, such as parcel delivery, these packages are an essential component of Amazon’s initiative to reduce packaging waste and enhance customer satisfaction by eliminating the need for over-boxing.

Type B packaging is crucial within the SIPP program, designed to navigate through Amazon’s logistical network directly to consumers, supporting Amazon’s frustration-free packaging goals. This initiative emphasizes ease of opening, the incorporation of recycled materials, and the minimization of waste through optimized packaging size and weight.

ISTA 6 SIPP Type B Verification Process

The ISTA 6 SIPP Type B verification process aims to rigorously assess the protective capabilities of a package. Developed in collaboration between Amazon and the International Safe Transit Authority (ISTA), these tests subject packages to various stress tests including vibration, shock, and drop tests, with preconditioning applied when necessary.

This verification process is meticulously designed to mirror the physical challenges packages face within Amazon’s fulfillment environment, evaluating both the packaging and its contents for potential damage.

To assist sellers and vendors in navigating these requirements, Amazon has established the Amazon Packaging Support and Supplier Network (APASS), which includes accredited labs like Keystone Package Testing.

These labs are proficient in the nuances of package testing requirements, registration on Seller Central, and preparation standards, thereby facilitating seamless vendor enrollment and package testing for Amazon.

Necessity of Package Certification

Certification becomes imperative under the following circumstances:

  • Launching new products or packaging on Amazon.
  • Implementing design changes to existing products.
  • Adapting to new Amazon packaging requirements that render previous exemptions void.
  • Addressing observed shipping damages to customers by Amazon.
  • The benefits of undergoing package testing are significant, including expedited market entry, optimized distribution costs, minimized product damage and loss, improved customer satisfaction, and bolstered confidence in product launches.

Criteria for Unacceptable Packaging

Amazon maintains rigorous packaging standards to ensure safe and sustainable product delivery. The evaluation of packaging focuses on its ability to withstand specific tests, emphasizing durability and protective capability.

Certain design features automatically disqualify packaging, including:

  • Boxes lacking tape, which are crucial for sealing and security.
  • Packaging with protruding elements such as tuck flaps, tabs, and handles that pose risks of catching or tearing.

Moreover, Amazon prohibits:

  • Packaging that exposes the product through cut-outs.
  • The utilization of plastic bags or non-protective coverings.
  • Packaging that deforms under stress, indicating inadequate strength.
  • Non-standard boxes that lack a six-sided construction.

These standards underscore Amazon’s dedication to delivering quality experiences while advocating for environmentally responsible packaging practices.

Amazon SIPP Type B Pass/Fail Determinants

Determining the pass/fail criteria for Type B certification involves a collaborative pre-test dialogue among shippers, manufacturers, Amazon, and other relevant stakeholders. This collaboration aims to clearly define parameters for acceptable post-test packaging conditions, damage thresholds, and methodologies for assessing the condition of the product, ensuring a comprehensive and unified approach to packaging certification.
