Why Costco code CB-PKG deductions happen
Club-pack configuration did not match Costco's specification — wrong unit count per pack, missing IRC, missing item-level UPC, or shrink-wrap failure. In practice, this is rarely a single root cause. Costco's receiving and audit systems flag club-pack / packaging non-compliance 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 CB-PKG packet hinges on documentation timing, not on whether the shipment was actually correct.
How to prevent Costco code CB-PKG going forward
Lock club-pack spec with Costco buyer in writing; QA finished packs against spec at random intervals; rotate QA samples weekly.
Filing wins back the dollars; the SOP fix is what stops you from filing the same dispute again next quarter.
