These charges are deducted from your payment automatically. No invoice, no negotiation, no warning. For produce suppliers, SQEP barcode defects are one of the top five sources of chargeback losses. Here is every barcode-related defect type Walmart tracks and exactly what causes each one. How SQEP Works When a Walmart distribution center receives your shipment, their dock-door scanning system reads every pallet label automatically. The scan data is compared against your ASN (EDI 856), your PO, and Walmart's compliance database. Any discrepancy triggers a SQEP event. The charge is applied to your remittance without prior notice. SQEP charges for barcode defects typically range from $200 to $500 per occurrence. On a multi-pallet shipment with a systematic label error, the total can exceed your profit margin on the load. Defect Type 1: Barcode Not Readable The barcode cannot be decoded by Walmart's scanner. Causes: inkjet-printed labels (smear in cold chain), torn or wrinkled labels, labels applied over seams or edges, insufficient print resolution (below 203 DPI), damaged quiet zones (blank space beside the barcode). Fix: Use a Zebra thermal printer, minimum 203 DPI, with genuine Zebra label stock. Inspect every label before application. Never apply a label over a box seam, staple, or surface irregularity. Defect Type 2: SSCC Not on ASN The pallet's SSCC barcode was scanned, but that SSCC does not appear in the ASN Walmart received. Causes: ASN transmitted before labels were finalized, pallets relabeled after ASN transmission, ASN transmission failed silently (no acknowledgment confirmed). Fix: Finalize all pallet labels before transmitting the ASN. Confirm ASN acknowledgment (997 EDI transaction) before the truck departs. Never relabel a pallet without retransmitting the ASN. Defect Type 3: SSCC Already Used The SSCC on your label was previously used on a different shipment. Walmart's system flags duplicate SSCCs as a compliance violation. Cause: SSCC counter not incrementing correctly, reuse of old label templates, manual SSCC entry with errors. Fix: SSCCs must be unique across all shipments, forever. Use a system that automatically generates sequential SSCCs from your GS1 Company Prefix. Never reuse an SSCC. Defect Type 4: GTIN Mismatch The GTIN encoded in the barcode doesn't match the GTIN registered for that item in Walmart's item database. Causes: outdated label template referencing an old GTIN, typo in GTIN during label setup, product reformulation that changed the GTIN without updating label templates. Fix: Verify your GTIN against Walmart's item database (through Retail Link) before every print run. A GTIN is item-specific — if the product changes, the GTIN changes. Defect Type 5: Missing Mandatory Application Identifier The barcode is scannable but is missing a required field. Walmart requires these AIs on every produce pallet label: (00) SSCC, (02) GTIN, (10) Lot Number, (13) Pack Date, (30) Count. If any of these are absent, the scan fails the compliance check even if the barcode itself reads correctly. Fix: Validate your label template to confirm all mandatory AIs are present before any production run begins. Defect Type 6: Label in Wrong Location The label is physically positioned outside Walmart's acceptable placement zone. Required: lower-left corner of each pallet face, between 15 and 40 inches from the floor, on the side facing the dock door. Labels on the top of the pallet, on stretch wrap only (not the pallet itself), or above 40 inches will not be scanned by dock-door readers. Fix: Train receiving and labeling staff on exact placement. Place a height marker on your pallet staging area at 15 and 40 inches. Defect Type 7: Wrong Label Size Labels smaller than 4x6 inches don't meet Walmart's minimum size requirement. The barcode elements (quiet zones, bar height) cannot be encoded correctly on an undersized label. Fix: Use 4x6 inch label stock. This is the universal standard for pallet labels in the US food supply chain. Defect Type 8: Human-Readable Information Missing or Wrong The human-readable text above the barcode (PO number, Ship-To, Ship-From, item description) is missing, truncated, or doesn't match the barcode data. Walmart receiving staff use this for visual verification before scanning. Fix: Your label template must include all human-readable fields, generated from the same data as the barcode — not typed separately. Disputing a SQEP Charge Walmart allows SQEP charge disputes through Retail Link. The dispute window is typically 30 days from the charge date. You'll need: your original ASN transmission with timestamp, a scan of the actual label (or a reprint of the same template), and documentation showing the label met specifications. Approval rates for disputes with strong documentation are roughly 40–60%. Disputes without documentation are almost never successful. The better strategy is preventing defects entirely. Every SQEP charge you avoid is money that stays in your margin. Tag Verify validates your Walmart shipment data against current SQEP requirements before generating the barcode. Each label is confirmed compliant — correct GTIN, valid SSCC, all mandatory fields present — before it ever prints.
