The eCommerce world continues to evolve rapidly, and Walmart Fulfillment Services (WFS) has introduced several major updates in 2025. Whether you’re a new Walmart seller or already managing your operations through WFS, understanding these changes is essential to stay competitive in one of the world’s largest online marketplaces.
From fee adjustments and API improvements to simplified product setup and expanded delivery coverage, this updated guide from Xomitt breaks down what’s new, what’s changed, and how you can use these updates to your advantage.
In today’s marketplace environment, where speed, accuracy, and customer experience define success, sellers can’t afford to ignore the impact of fulfillment on growth. Walmart is positioning WFS as a powerful alternative to Amazon FBA, offering faster delivery speeds, integrated logistics, and lower costs for sellers who meet compliance standards. These updates are part of Walmart’s broader strategy to make its marketplace more seller-friendly and scalable, ensuring brands can reach millions of active buyers without compromising quality or profitability.
Over the past few years, WFS has evolved from a basic fulfillment option to a comprehensive logistics ecosystem. The introduction of Next-Day Delivery, cross-border import options, and new automation APIs marks a significant step toward building a seamless seller experience. With these upgrades, Walmart aims to strengthen its competitive edge in U.S. eCommerce and empower more third-party sellers to join its platform confidently.

Sellers who act early and align their operations with these improvements can expect higher visibility, lower storage costs, and improved conversion rates throughout the year. In this in-depth guide, Xomitt walks you through every change from technical upgrades to operational best practices helping you make informed decisions and achieve long-term success on Walmart Marketplace.
What’s New in WFS: The Major 2025 Changes
The 2025 updates to Walmart Fulfillment Services reflect Walmart’s goal of making its marketplace more efficient and seller-friendly. Here’s a breakdown of the biggest changes:
1. Streamlined Item Spec (Spec 5.0)
Walmart has rolled out Item Spec version 5.0, making product listing simpler and faster.
Previously, sellers had to provide numerous attributes for each product. Now, under Spec 5.0, only essential product details are required, including:
- A single Product ID (GTIN)
- Dimensions and weight
Many older fields like Orderable GTIN, Each GTIN, and case/inner pack/pallet details have been removed or simplified.
For fashion categories, detailed attributes such as footwear shaft circumference, sole material, or bag closure type are no longer mandatory. They’ve been shifted from “required” to “recommended”, making it easier for apparel and accessory sellers to onboard faster.
2. Waived Peak-Season Storage Fees for Q4 2025
Walmart is helping sellers manage holiday-season inventory costs by waiving peak-season storage fees from October 1 through December 31, 2025.
Normally, inventory stored for more than 30 days during peak periods incurs a higher storage fee (around $1.50 per cubic foot/month). During this waiver period, sellers will pay only standard storage rates (approximately $0.75 per cubic foot/month) for eligible items.
This update provides a huge opportunity to stock up for Q4 demand without worrying about inflated storage costs.
3. Expanded Delivery & Fulfillment Options
The Next-Day Delivery coverage under Walmart Fulfillment Services has expanded significantly in 2025.
Now available in major metro areas such as Los Angeles, New York, Chicago, Houston, and Atlanta, sellers can reach more customers with faster shipping tags.
Walmart has also enhanced its Multichannel Solutions (MCS) allowing sellers to fulfill orders from multiple channels (like their own eCommerce site, social media stores, or other marketplaces) using Walmart’s fulfillment network.
This means centralized logistics, reduced overhead, and smoother operations for growing brands.
4. New & Enhanced Tools + APIs
To improve automation and accuracy, Walmart released several new APIs and tool updates for sellers in 2025.
Here are the key enhancements:
- Inventory Reconciliation API – Helps track item movement and resolve stock mismatches between your system and Walmart’s fulfillment centers.
- Recommended Shipment Quantity API – Suggests how much inventory to send, preventing both overstocking and out-of-stock scenarios.
- WFS Preferred Carrier APIs – Automates carrier selection for more efficient shipping workflows.
- Listing Tools Updates – Improved single and bulk upload systems with less redundancy, making SKU creation faster and error-free.
These automation upgrades help sellers save time, reduce manual errors, and improve fulfillment accuracy.
5. Cross-Border & Import Solutions
For sellers sourcing products from Asia (China, Vietnam, India), Walmart has made importing smoother through its Cross-Border Imports program.
This service lets items ship directly from ports in Asia to Walmart’s U.S. fulfillment centers, cutting lead times, reducing logistics costs, and improving supply chain efficiency.
6. Seller Incentives & Fee Structure Adjustments
To encourage marketplace growth, Walmart has introduced special incentives and fee adjustments in selected categories.
Key highlights:
- Waived referral fees or reduced rates in certain high-growth categories (like pets, toys, and seasonal items).
- Fulfillment costs under WFS remain on average ~15% lower compared to other fulfillment providers depending on product dimensions and delivery distance.
- Performance-based bonuses and visibility boosts for sellers maintaining top-tier metrics (shipping accuracy, return rates, customer ratings).
These initiatives make WFS an increasingly cost-effective and scalable fulfillment option.

Challenges to Watch Out For
Despite the progress, sellers should remain aware of potential WFS pitfalls:
- Long-Term Storage Fees: Items stored for several months can still incur high long-term rates. Maintain strong inventory hygiene to avoid these costs.
- Compliance & Labeling: Even with simplified specs, incorrect labels or missing barcodes can cause rejections or unplanned prep fees.
- Competition & Visibility: As more sellers optimize for faster delivery, standing out requires high-quality listings, competitive pricing, and strong reviews.
- Returns & Brand Control: WFS manages returns, but sellers have limited control over packaging, insert materials, or return handling policies.
Anticipating these issues can protect your profit margins and improve your overall operational consistency.
