Why Costco code CB-RTG deductions happen
Trailer arrived outside the booked appointment window or routed through wrong depot. Costco depots run tight dock schedules. In practice, this is rarely a single root cause. Costco's receiving and audit systems flag routing / appointment 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-RTG packet hinges on documentation timing, not on whether the shipment was actually correct.
How to prevent Costco code CB-RTG going forward
Book appointments earlier in the window; pre-stage trailers near high-volume depots; never miss an appointment without rescheduling.
Filing wins back the dollars; the SOP fix is what stops you from filing the same dispute again next quarter.
