Costco Chargeback Code ASN-LATE: Late or inaccurate ASN
What this deduction means
Assessed when the 856 ASN is transmitted after the freight departs or doesn't match the physical shipment. Because Costco runs a cross-dock depot model, missing or wrong ASN data can hold freight at receiving and cascade delays to multiple club locations.
Typical penalty: Roughly $50–$200 per incident; can also trigger shipping holds
Common causes
- ASN sent after the truck left, or not at all
- Carton/pallet hierarchy in the ASN not matching the physical load
- ASN quantities differing from what was actually shipped
How to prevent Costco code ASN-LATE
- Transmit the 856 before or as freight departs, never after
- Generate the ASN from actual pick/pack scan data, not the PO
- Monitor 997 acknowledgments so a rejected ASN is re-sent before arrival
