Why Walmart code 10 deductions happen
DC found shortage after carton was opened (inner-pack count low). Common on shrink-wrapped club packs and inner-case product. In practice, this is rarely a single root cause. Walmart's receiving and audit systems flag concealed shortage the moment a discrepancy hits the threshold — so even a clean shipment can take a deduction if the paperwork or the EDI handshake doesn't reconcile cleanly on the retailer's side. That's why almost every code 10 packet hinges on documentation timing, not on whether the shipment was actually correct.
How to prevent Walmart code 10 going forward
Audit pack-out line at random intervals; weight-verify finished cases against bill of materials before shipping.
Filing wins back the dollars; the SOP fix is what stops you from filing the same dispute again next quarter.
