Step-by-step: how to dispute Costco code CB-RTG

  1. 1

    Confirm the deduction is in scope

    Locate the deduction on your Costco remittance and confirm the reason matches code CB-RTG (Routing / appointment non-compliance). Note the deduction post date — your filing window starts there.

  2. 2

    Pull the evidence packet

    Gather: Appointment confirmation, carrier GPS/ELD record, depot arrival timestamp, and any depot-acknowledged exception.

  3. 3

    File the dispute in Costco Supplier Portal

    Open Costco Supplier Portal, locate the deduction, and attach your evidence packet. Filing window: 60 days from chargeback date. Late filings are auto-denied — file as soon as the packet is complete.

  4. 4

    Track the response

    Most Costco dispute responses land in 30–60 days. Approved disputes are credited on the next remittance cycle. Denied disputes can be re-filed once with additional evidence; track the re-file deadline.

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.
