Overview

Amazon's Ships in Product Packaging (SIPP) program allows products that are already packaged in durable, ship-ready containers to be sent directly to customers without additional Amazon overboxing. For FBA sellers, qualifying for SIPP can reduce packaging waste, lower fulfillment costs, and speed up the shipping process. Understanding the program's specific packaging tiers and design criteria is essential for sellers looking to take advantage of these benefits.

Key Points / What Sellers Need to Know

• Two packaging tiers exist — SIPP classifies qualifying products into Tier 1 (flexible packaging like bags and mailers) and Tier 2 (rigid six-sided packaging like boxes), each with distinct requirements.
• Minimum thickness matters — Flexible packaging materials must be at least 2 millimeters (0.08 inches) thick to qualify, ensuring products survive transit without additional overboxing.
• Sealed packaging is mandatory — All SIPP-eligible items must arrive at Amazon fulfillment centers in packaging that is fully sealed and ready to ship as-is.
• Catalog evaluation required — Sellers must review their existing product lineup against SIPP criteria before enrolling, as not every item will meet the standards.
• Testing and documentation — Amazon provides tools to test your packaging and record results, which are part of the enrollment workflow.

How the SIPP Program Works

When a product qualifies for SIPP, Amazon's fulfillment centers ship the item directly in the seller's own packaging rather than placing it inside an additional Amazon-branded box. This means the customer receives the product in whatever container the seller designed and submitted to FBA. The program is designed to eliminate unnecessary packaging layers, which reduces material costs for Amazon and can translate into lower per-unit fulfillment fees for sellers. To participate, sellers identify qualifying ASINs in their catalog, ensure the packaging meets one of the two tier standards, and then enroll through Seller Central.

Tier 1: Flexible Packaging Requirements

Tier 1 covers products packaged in flexible exterior materials such as poly bags, paper bags, padded mailers, or rigid mailers. The key requirement is that the packaging material must be at least 2 millimeters thick, providing enough durability to protect the product during shipping without an overbox. The packaging must be fully sealed so that no additional taping, wrapping, or enclosure is needed at the fulfillment center. Products in thin, flimsy bags or unsealed pouches will not qualify. Sellers should consider whether their product can withstand being tossed, stacked, and handled in a flexible mailer before applying for this tier.
