Walmart Marketplace shipping requirements: lag time, ship-by date and auto-cancel
Walmart sets the dates, and you have to hit them. Miss the ship-by date by four days and the order is cancelled automatically. Here are the rules from Walmart’s Shipping & Fulfillment Policy.
The minimum requirements
- Ship within 2 operational days of receiving an order (your fulfillment lag time), unless Walmart approved a lag time exemption.
- Ship until 11:00 am your local time, at least five days a week, with your days set for each fulfillment center.
- Support at least one shipping method.
- Choose a lag time, carrier and service level that deliver on or before the Expected Delivery Date.
- Additional Days Off: up to 30 per fulfillment center per calendar year, for exceptional cases only. Overuse can lead to suspension or termination.
- Provide accurate, valid tracking, and only after the package is handed to the carrier. No stamps or prepaid envelopes — every order needs a valid tracking number.
When an order must ship
The Expected Ship Date is when the order must be marked Shipped with valid tracking.
| Lag time | Order received | Must ship by |
|---|---|---|
| 0 days | Before order cutoff | Same operational day |
| 0 days | After order cutoff | Next operational day |
| 1 day | Any time | Order date + 1 operational day |
| 2 days | Any time | Order date + 2 operational days |
The order cutoff time only matters when lag time is 0. By default it’s 2:00 pm local time, with Monday–Friday as operational days — set your own in Seller Center, or your on-time shipping can suffer. Lag time changes can take up to 24 hours to show on Walmart.com.
Auto-cancellation
If an order isn’t marked Shipped with tracking by the Expected Ship Date plus four calendar days, Walmart cancels it. Walmart’s example: an Expected Ship Date of Monday is auto-cancelled on Friday. If you ship an auto-cancelled order anyway, Walmart doesn’t have to reimburse you.
After shipping, if an item is five days past the Expected Delivery Date with no carrier movement in three days, Walmart considers it to be in a terminal state and can cancel the order — and you pay the costs.
Delivery dates and search ranking
The delivery date customers see is based on your historical on-time delivery rate, your carrier’s data and Walmart’s logistics insights — and Walmart says this date also affects your search ranking. Walmart can extend your delivery promise (you can’t opt out of that), and you can opt out of having it shortened under Shipping Info → Delivery Promise Optimization.
What’s banned
- Retail arbitrage — buying from another retailer and having them ship to your customer.
- Shipping in competitor boxes or packaging, or packaging that names anyone other than the manufacturer or you.
- Promotional inserts — surveys, requests for reviews, coupons or offers.
- Marking an order Shipped before it physically ships.
Walmart says even a single violation can lead to action such as suppressed listings, selling limits or withheld funds.
Amazon Multi-Channel Fulfillment is allowed — but only in a neutral box, and you must block Amazon Logistics as a carrier so orders don’t arrive in Amazon-branded vehicles.
Tracking tips
- Walmart’s pages differ on how long you can edit a tracking number after marking an order Shipped: four hours here, but up to 24 hours or until the first carrier scan in the valid tracking policy — see Walmart valid tracking. Fix mistakes right away.
- Small or regional carriers that aren’t integrated with Walmart may stop you meeting the 99% valid tracking standard.
