Walmart Chargeback Code 13: Substitution billed at a higher cost
Extracted from source — pending expert reviewLast verified: 2026-07-09
What this deduction means
A Code 13 is assessed when a supplier ships and invoices a substitute item at a higher cost than the item Walmart actually received. Walmart deducts the cost difference between the invoiced item and the item received.
Typical penalty: Equal to the cost difference between the invoiced and received item
Common causes
- Substituting an item without updating the invoiced cost
- Billing the ordered item's cost when a cheaper substitute shipped
- Item/UPC mismatch between the shipment and the invoice
How to prevent Walmart code 13
- Invoice the item and cost that actually shipped, not the ordered item
- Avoid unauthorized substitutions; confirm any substitution with Walmart
- Reconcile UPC and cost on the invoice against the physical shipment
