Overview

Amazon's Ships in Product Packaging (SIPP) program rewards sellers whose products can ship in their original packaging without additional Amazon boxes. Starting January 15, 2026, the program is undergoing significant changes that affect how discounts and fees are applied across different product size tiers. Sellers who participate in SIPP can save money on fulfillment fees, while those who don't enroll may face new packaging charges.

Key Points / What Sellers Need to Know

• Standard-size SIPP discounts continue — Products classified as standard-size will keep receiving per-unit fulfillment fee discounts when certified under the SIPP program, ranging from $0.04 to $0.23 depending on weight.
• Large bulky and extra-large changes — For larger items, Amazon is replacing the flat SIPP discount with lower base fulfillment fees for enrolled products, rather than applying a separate per-unit discount.
• New packaging fee for non-enrolled products — Starting January 15, 2026, products that require Amazon to provide packaging but aren't enrolled in SIPP will be charged a packaging fee averaging $2.07 per unit.
• Enrollment is available through Seller Central — Sellers can enroll products through the SIPP enrollment portal, and some products may be auto-enrolled by Amazon.
• Weight limit applies — Only products weighing 20 pounds or less are eligible for SIPP certification discounts on standard-size items.

How the SIPP Enrollment Process Works

Sellers who want to enroll products in SIPP can do so through the dedicated enrollment portal in Seller Central. When submitting products that aren't currently certified, Amazon requires sellers to provide a "first arrival date" — the date when SIPP-compliant inventory will first arrive at Amazon's fulfillment centers. This date is important because discounts only apply to units received after that date, not to existing inventory already in warehouses. For example, if a seller completes enrollment on March 1 but won't ship compliant packaging until April 1, the first arrival date should be set to April 1. If the product's current packaging already meets SIPP standards, sellers can enter the current date. Once enrollment is approved, all future units must maintain SIPP compliance or risk losing certification.
