How To Run A Relabeling Operation In Your Warehouse

Replacing or correcting labels on products, cartons, or pallets to meet updated requirements.

Relabeling Replacing or correcting labels on products, cartons, or pallets to meet updated requirements. Running relabeling as a controlled, repeatable operation reduces errors, speeds throughput, and protects compliance. This article gives a practical, step-by-step approach to set up relabeling stations, standard operating procedures (SOPs), quality checks, and metrics warehouses should track.

Successful relabeling is part planning, part equipment, and part governance. The goal is to make corrections without interrupting the rest of the warehouse. Typical targets for optimization include minimizing touches per unit, ensuring accurate data capture, and keeping relabeling segregated from live picking and packing flows.

Set Up A Dedicated Relabeling Station

Allocate a bench or bay close to receiving or returns but separated from high-traffic picking lanes. A standard station includes a label printer (thermal transfer for durability), a PC or tablet with WMS access, a handheld scanner, label removal tools, adhesive solvent and waste receptacle, and strong lighting for visual inspection. For larger runs include a barcode verifier to test print quality and scanners that can read 1D and 2D codes.

Write Clear Standard Operating Procedures

SOPs should specify acceptance criteria (when relabel is allowed versus when repackaging or quarantine is required), label templates, label placement rules, removal versus over-label policies, and how to record work in the WMS. Include step-by-step instructions: pull list generation, unit staging, label removal (if needed), label application, verification steps, and how to mark an item as completed. Train staff on SOPs and keep printed copies at the station.

Quality Control And Verification

Every relabel should be verified. Best practice: a two-step verification where the operator scans the inventory, applies the label, and a second operator or an automated scanner verifies the printed barcode, lot, expiry, and GTIN against the work order. For high-value, regulated, or serialized goods add photographic evidence and a signature log. Use barcode verifiers periodically to confirm label readability to GS1 standards.

WMS And Data Integration

Integrate relabel work orders with the WMS so inventory status is frozen or put on hold until corrections are complete. The WMS should track quantity corrected, operator ID, time stamps, and reason codes. Where possible, generate labels from the WMS/ERP to avoid template mismatch and reduce human error. For retailer-specific labels automate template selection through EDI or API mapping.

Safety, Waste, And Environmental Controls

Label removal creates adhesive waste and sometimes chemical solvents. Provide PPE, solvent-safe waste containers, and clear procedures for solvent use and disposal. Minimize over-labeling when adhesives can damage the product or packaging. Consider recycling policies for removed labels and cardboard to support sustainability goals.

Metrics To Track

• Throughput: Units relabeled per hour or per shift.
• Accuracy: Percentage of relabels that pass verification on first check.
• Cost Per Unit: Labor + materials divided by relabeled units.
• Rework Rate: Percentage of relabels requiring rework or escalation.
• Downtime Causes: Printer jams, template errors, or missing materials logged for continuous improvement.

Practical Example: Rapid Relabel For A Retailer Change

A retailer updates its carton label requirements with a 10-day lead time. The warehouse receives a 5,000-carton shipment with old labels. The operations manager sets up a relabeling lane, assigns two teams to run 8-hour shifts, reserves a staging area, and runs hourly verification. WMS holds inventory until labels are verified and released. The run finishes in three days with full traceability and no shipments delayed.

Continuous Improvement And Prevention

After each significant relabel event conduct a root-cause review. Common fixes include earlier communication with suppliers, template centralization in the WMS, or shifting to pre-printed labels at origin. Where relabeling happens frequently consider adding pre-shipment label checks at supplier sites or requiring supplier-side labeling agreements to reduce downstream work.

In short, Relabeling is an essential warehouse capability for correcting label errors and meeting customer or regulatory requirements. A successful relabel operation requires a dedicated station, clear SOPs, WMS integration, verification controls, and continuous improvement to minimize frequency and cost.
