Analysis & Recommendations
Why This Matters
If the required attributes are missing or enumeration values are outdated, Amazon will reject the listing, halting sales pipelines for any system that relies on the Listings Items API or JSON LISTINGS FEED. The mandatory rollout on Feb 23 2026 leaves a short window for remediation, making immediate compliance essential to avoid revenue loss.
Key Takeaways
- Effective date is February 23 2026 for all Amazon marketplaces.
- Attributes “material” (apparel) and “brand” (footwear) switch from optional to required.
- Enumeration lists now include new options such as “trail” and “cross‑train” for shoe type.
- Legacy XSD/XML feed format is exempt; only Listings Items API and JSON LISTINGS FEED are affected.
Recommended Actions
- →Download the latest product‑metadata CSV/JSON from the SP‑API documentation page (Seller Central > Developer Central > SP‑API product‑metadata).
- →Update your Listings Items API and JSON LISTINGS FEED code to add required fields (e.g., "material": "cotton", "brand": "Nike").
- →Add a validation step in your integration that checks payloads against the new enumeration lists before sending to Amazon.
