Costco vendor compliance: how chargebacks work
Costco's compliance model is shaped by its depot cross-dock network: freight must arrive exactly on appointment, labeled and palletized so it can flow straight through to clubs. Chargebacks are assessed case-by-case rather than through a published numbered-code system.
Indicative figures compiled from public and industry sources; fine amounts and thresholds change, so confirm current values in Costco Supplier Portal. How we verify.
Compliance programs to know
Depot compliance
Case-by-case charges for late or refused deliveries, GS1-128/SSCC label defects, pallet configuration failures, quantity discrepancies, and PO/invoice mismatches.
Costco chargeback codes by category
We track 6 Costco codes across 6 operational areas, the part of your shipping and invoicing flow where each deduction actually originates.
Disputing Costco deductions
Compliance documentation and routing guides live in the Supplier Portal. Because charges are case-by-case, disputes hinge on shipment evidence: ASN records, label validation, pallet photos, and signed delivery paperwork.
