Costco Chargeback Code LABEL-GS1: Incorrect GS1-128 / SSCC label
What this deduction means
Assessed when carton or pallet GS1-128 labels carry invalid data — a bad SSCC (Serial Shipping Container Code), unscannable barcode, or label data that doesn't match the 856 ASN hierarchy. Mislabeled freight slows Costco's cross-dock flow and can delay the whole shipment.
Typical penalty: Approximately $5–$10 per mislabeled carton
Common causes
- SSCC codes generated outside the supplier's GS1 Company Prefix
- Label data not matching the ASN carton/pallet hierarchy
- Unscannable barcodes from poor print quality or wrong placement
How to prevent Costco code LABEL-GS1
- Generate SSCCs from your registered GS1 Company Prefix and validate before printing
- Drive label generation and the 856 ASN from the same shipment data
- Scan-test labels before the truck is loaded
