Transition Alert: Walmart to Sunset Item Spec 4.x – Migrate to 5.x by August 31
Walmart Marketplace is evolving again - this time with a significant change to its item setup infrastructure. Sellers still using older spec versions (3.x and 4.x) must act quickly to avoid disruption. Xtended.GH is here to guide you through the changes and ensure your listings stay compliant and competitive.
What’s New
Walmart has announced that support for Item Spec 3.x ends on June 30, 2025, and support for 4.x ends August 31, 2025. Sellers must migrate to Item Spec 5.x, also known as Omni Spec 5.x, which provides:
Enhanced data accuracy
Simplified item maintenance
Compatibility with new Product Type attributes
Why This Update Matters
Failure to migrate can result in listing errors, suppressed products, or loss of Buy Box opportunities. With Walmart pushing for cleaner and more standardized data, sellers who delay the update risk losing traction and visibility on the platform.
Pro Tips from Xtended.GH
Audit your current listings to identify those still using 3.x or 4.x
Begin item mapping to 5.x templates now to avoid a last-minute rush
Update Product Type attributes carefully - they’re the key to clean, compliant data
Maintain a changelog for every migrated listing for future troubleshooting
