Overview

Amazon has updated its Ships in Product Packaging (SIPP) program to let sellers certify a set of similar SKUs with a single packaging test. The change, announced in early 2024, groups variations that share size, weight and packaging characteristics, eliminating the need for a separate test report for every ASIN. Sellers with multiple flavors, colors or sizes can now enroll faster and cut testing expenses.

Key Points

• Grouped certification — Sellers may bundle physically alike ASINs into one test, reducing the number of required reports.
• Primary product rule — The heaviest and largest item in each group is treated as the primary product; its successful test validates the entire group.
• Secondary ASIN inclusion — Variations that differ only by flavor, scent, color or size can be added without additional testing.
• Eligibility report — A downloadable CSV shows which catalog items are already certified, which qualify for grouping, and where gaps remain.
• Exception categories — Liquid goods and fragile items often still need individual testing even after a primary product passes.

How Grouped Certification Works

1. Identify recommended group — Amazon scans a seller’s catalog and clusters SKUs that share dimensions, weight and packaging type. For example, a line of 12‑oz vitamin bottles in five flavors would be placed in one group.
2. Select primary product — Within each group, the system flags the heaviest and largest SKU as the primary product. If the “Berry Blast” flavor weighs 150 g and the others weigh 140 g, “Berry Blast” becomes the primary.
3. Conduct single packaging test — The seller submits one test report for the primary SKU. Passing this test confirms that the packaging can protect the product during Amazon’s fulfillment process.
4. Enroll secondary ASINs — After the primary test is approved, the remaining flavors—e.g., “Citrus Zest,” “Tropical Twist,” and “Green Apple”—are automatically certified under the same report. No extra lab work is required.
