Overview

On November 9 2025 Amazon will enforce tighter listing attribute rules for a wide range of product types. The changes apply to any seller or developer who creates or updates listings via the Selling Partner API (SP‑API) or the JSON LISTINGS FEED, and missing the new fields will cause immediate rejection—right before the holiday rush.

Key Points

• New mandatory fields — Attributes that were optional, such as “BatteryLife” for electronic devices in the US marketplace, will become required; a submission lacking this data will fail validation.
• Expanded enumeration options — Dropdown lists now contain more granular choices, for example “WirelessStandard” now includes “Wi‑Fi 6E” and “Wi‑Fi 7,” allowing sellers to describe products with higher precision.
• Marketplace‑specific rules — The United Kingdom may demand a “PowerPlugType” attribute for kitchen appliances, while the German marketplace adds a “EnergyEfficiencyClass” field for the same category.
• Hard‑stop API validation — After the enforcement date, any SP‑API call that omits a newly required attribute returns a 400 error with a clear message; there is no warning grace period.
• Metadata schema overhaul — The internal product‑type definitions used by the SP‑API are being revised, meaning version numbers in the API schema will change and integrations must reference the updated schema.
• Impact on third‑party tools — Even sellers who never touch the API directly are affected if their listing‑management software relies on the SP‑API; an outdated tool will start rejecting uploads.
• High‑volume categories at risk – Categories like “Home Improvement” and “Electronics” contain the most new mandatory attributes, so sellers with large inventories in these areas face the greatest workload.
• No automatic back‑fill — Amazon will not populate missing attributes retroactively; sellers must supply the data before the listing can go live.
• Testing requirement — Amazon recommends sandbox testing for each marketplace; a failure in the sandbox mirrors the production rejection behavior exactly.
