Overview

When you use Walmart Fulfillment Services (WFS), you’ll send inventory to our fulfillment centers. Items and shipments must meet our guidelines so we can quickly receive and store your inventory. In this guide, we’ll explain the high-level requirements for labeling, packing and shipping.


For more details, download the WFS Routing and Packaging Guide. It should be your go-to source for guidelines, and we continually update it with new guidance.

WFS product requirements

Items that meet these requirements are perfect for WFS:

  • Up to 500 lb., including packaging
  • Maximum dimensions of 120″ x 105″ x 93″, including packaging
  • No regulated or perishable items that require temperature control
  • Must ship to Walmart fulfillment centers from within the US or clear customs before arriving at our facilities
  • Must be items that are permitted in the WFS program. See the WFS Prohibited Products and Marketplace Prohibited Products Policy for details

    Products that contain chemicals, aerosols, pesticides or batteries must pass a compliance review before they’re published on Walmart.com.

Preparing items

To avoid delays, items must meet labeling and packing requirements. Some of these include:

Packing

  • Item packaging must reasonably protect the item from damage during shipping. The packaging should also keep the item contained throughout transit.
  • All items must be protected in a sealed or closed container, ready for sale.
  • Any item received as ready to ship in a shippable container may still be repackaged at the discretion of the fulfillment center.
  • Packaging inserts and other forms of marketing materials are acceptable as long as they don’t advertise competing services.


Item labels

  • All items must be labeled with a GTIN or UPC barcode. You may choose to buy a unique barcode from GS1.
  • Price tags, item labels and retailer-specific labels should not be on the item packaging.
  • All required hazard warnings must be clearly visible and apparent on all poly bags used.
  • Expiration or “best by” dates must be displayed in the format MM-DD-YYYY. If you don’t know the exact date, use the first day of the expiration month.
  • All items must be marked with the country of origin. The label must be located where it can be seen while casually handling the item. For example, clothing may have a label on the collar stating “Made in . . .”


*Your item is sortable if it's <30 lb. with a maximum packaged dimension ≤25", a median packaged dimension ≤20", and a minimum packaged dimension ≤14".

Preparing shipments

If you’re shipping small parcel, use master cases. You may load cases directly onto the truck as floor loads. If you’re shipping less than truckload (LTL) or full truckload (FTL), you must use pallets.


Master cases

WFS accepts these standard case types:

  • Regular slotted carton (RSC)

  • B flute

  • ECT-32 (edge crush test)

  • 200 lb./sq inch (burst strength)


Each case can weigh up to 150 lb, unless it contains a single unit that exceeds 50 lb. Do not bundle cases using bagging, taping, elastic or extra straps.


Packing material

Some items should be shipped with packing materials to prevent damage. Follow these guidelines to choose the right materials.

Accepted

Not accepted

  • Foam
  • Air pillows
  • Bubble wrap
  • Full sheets of paper
  • Styrofoam
  • Styrofoam peanuts
  • Biodegradable packing peanuts
  • Cornstarch packing peanuts
  • Crinkle wrap
  • Shredded paper

Pallets

All pallets must meet these requirements:

  • Use 40" x 48", 4-way-access, solid-wood, Grocery Manufacturers Association (GMA) standard Grade A pallets.
  • Pallets may weigh up to 2,100 lb and be up to 72" in height.
  • Pallets must be in good condition, accessible and moveable using a standard pallet jack.
 

Double-stacked pallets are allowed, but must meet these additional requirements:

  • Do not exceed 108" in height, including the height of the pallets.
  • Use corner boards to help protect and stabilize master cases in transit.
  • Arrange pallets so a forklift can access them from the same side.
  • Stretch-wrap pallets to prevent damage during shipping and protect associates during unloading.


Case and pallet labels

  • A case containing a single oversize unit greater than 50 lb. requires "Team Lift" labels on the top and sides. If it contains a single oversize unit greater than 100 lb., use "Mech. Lift" labels on the top and sides.
  • If you’re reusing boxes from previous shipments, remove any previous labels or markings to avoid confusing the carrier.
  • Place a receiving label with the shipment ID onto each pallet: 4 per pallet, with 1 on each side in the top center.

Shipping items to WFS

You're responsible for sending inventory to Walmart using either the Walmart Preferred Carrier Program or your own carrier.


Seller shipping requirements

  • Ship items to your assigned Walmart fulfillment centers. In some cases, you may need to split inventory across multiple locations.
  • Do not send shipments to the Walmart corporate billing address. If you do so, shipments will be returned to you at your expense.

Third-party carrier requirements

If you choose to use their own carrier, the carrier must:

  • Be Department of Transportation (DOT) certified and registered.

  • Have a Retail Link account set up to use Walmart’s scheduling service.

  • Acknowledge that they will use only Walmart’s scheduling service for appointment needs.


Documentation

If you use a Walmart preferred carrier, we’ll generate a bill of lading for you. If you use your own carrier, you must use a bill of lading that’s specific to the Walmart facility. There should never be more than one bill of lading per location. The bill of lading must contain:

  • Shipment IDs – If multiple shipment IDs are shipped under one bill of lading, all shipment IDs must be listed
  • Complete destination (fulfillment center address)
  • Freight terms, e.g. "Prepaid"
  • Seller name and complete ship-from address
  • Ship date
  • Carrier name
  • Number of cases


For LTL shipments, you must also include accurate NMFC numbers (including subitem number, if applicable), NMFC class, number of cases and weight by item in the bill of lading.

Shipment delivery

Walmart may inspect items and test their packaging after arrival at the fulfillment center. It normally takes up to 2 business days to receive inventory from the time it was delivered. However, items that require unplanned prep work (e.g., incorrect labels), or that arrive during sales events, holidays, peak months (October 1–December 31), or other circumstances may take up to 10 business days to process. 

Notes

If you’re using Inventory Transfer Service, we split the inventory and distribute it nationwide. This means some of your inventory will instead typically be available to sell in 4 business days.

Damaged items

Any items received at a Walmart fulfillment center in a damaged or pilfered condition (concealed or otherwise) will be refused and/or returned to you at your expense. We’ll use the damages at receiving preferences that you provided in Seller Center to process damaged items. If you choose to have damaged items returned to you, we’ll use the WFS return address you provided.


Lost items

If you use your own carrier, you are responsible for any goods lost in transit to Walmart fulfillment centers and must manage all carrier claims.
