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

Amazon has refined its packaging requirements for vendors and sellers to mitigate returns and operational costs. In partnership with the International Safe Transit Authority (ISTA), Amazon has formulated a comprehensive suite of packaging test protocols. Specifically, the Amazon Type E package standard caters to Less Than Truckload (LTL) shipments weighing over 100 pounds, identified as ISTA-6 Type E.

This standard focuses on packages managed via standard handling procedures, simulating the varied conditions encountered within Amazon’s logistics network, including transportation impacts and fulfillment center environments.

ISTA 6 SIPP Type E Verification Process

Type E items fall under the Ships In Product Packaging (SIPP) classification, designed to be shipped in the vendor’s own packaging without additional Amazon boxing, thus eliminating over-boxing. Testing for these packages is conducted by labs accredited through Amazon’s APASS network, ensuring a comprehensive understanding of Amazon’s testing criteria, the package verification process, and enrollment procedures for Amazon vendors and sellers. Completion of these tests, evidenced by a detailed report submitted through Amazon Seller Central, avails numerous advantages.

The APASS program outlines a lab certification process for packaging test labs, offering significant benefits such as heightened confidence in product launches, reduced market entry times, and optimized distribution expenses. Central to this initiative is waste reduction, achieved by minimizing unnecessary packaging materials and dimensions, which in turn enhances customer satisfaction, brand reputation, and decreases returns. Amazon incentivizes participation with reduced or waived prep fees and chargebacks, though program specifics may periodically adjust.

Criteria for Unacceptable Packaging

Amazon assesses packaging based on test performance, excluding designs that fail to meet specific standards, such as unsealed or improperly constructed boxes, packaging that exposes the product, or lacks adequate structural integrity.

Non-compliance results from using non-taped closures, boxes with protruding elements, or packaging that inadequately protects the product, emphasizing the necessity of robust, six-sided designs.

Amazon SIPP Type E Pass/Fail Determinants

Establishing pass/fail benchmarks for SIPP packaging necessitates a collaborative approach among Amazon, shippers, manufacturers, and other stakeholders.

This collaboration focuses on defining acceptable levels of product damage, post-test packaging condition, damage tolerance, and assessment methods for evaluating product state post-test.
