Overview

Effective June 25 2025, Amazon will block all Merchant Fulfilled Network (MFN) listings that lack battery compliance information. Sellers must enter detailed data about any battery‑containing or battery‑powered product before a new or edited listing can be saved. This change eliminates the previous compliance gap between MFN and Fulfilled by Amazon (FBA) programs, forcing MFN sellers to meet the same safety standards.

Key Points

• Enforcement date — Starting 25 June 2025, Amazon will reject any MFN listing that does not include complete battery data.
• Three mandatory questions — Every battery‑related MFN listing must answer questions on battery necessity, inclusion, and chemistry; there is no “skip” option.
• Hard‑block mechanism — Listings cannot be created or updated until the required battery fields are filled; Amazon provides no warning period or temporary exemption.
• Standardized battery list — Sellers select from predefined chemistries such as lithium‑ion, lithium‑polymer, alkaline, nickel‑metal‑hydride, silver‑oxide, and zinc‑air, or manually input a custom type for niche batteries.
• Alignment with FBA rules — The new MFN requirement mirrors existing FBA dangerous‑goods protocols that already demand safety data sheets or exemption certificates for certain batteries.
• Catalog‑wide impact – Every existing MFN ASIN that contains a battery will need the new data before any future edit— even simple price changes or image swaps— or the listing will be locked.

How the Three‑Question System Works

1. Is a battery required for operation? — The system first asks whether the product cannot function without a battery. For example, a cordless drill that only works with an internal lithium‑ion pack must be marked “Yes,” triggering the next two questions.
2. Are batteries shipped with the product? — Sellers indicate if the battery is included, installed, or sold separately. A Bluetooth speaker sold with a pre‑installed lithium‑polymer cell receives a “Yes,” while a camera sold without a battery receives a “No,” which may skip the chemistry question.
