| 1 | Digital Printing Capability | Confirm whether the factory operates direct-to-garment or other digital sock-printing equipment suitable for the required fiber composition, sock size, and artwork complexity. | Current equipment list, production photographs or videos, sample prints, and a description of compatible fibers. | The supplier should demonstrate repeatable results on the actual sock construction and material required for the order. | 15% |
| 2 | Color Management | Assess color-matching controls, artwork preparation, calibration procedures, and the ability to maintain consistency between approved samples and bulk production. | Color approval workflow, printed strike-offs, color measurement records, and written tolerance criteria. | A pre-production sample should be approved before bulk manufacturing, with an agreed color tolerance and inspection method. | 12% |
| 3 | Ink Safety and Chemical Compliance | Check whether inks, dyes, auxiliaries, and finished socks meet the chemical requirements of the intended sales market. | Recent third-party laboratory reports, chemical declarations, safety data sheets, and applicable compliance documentation. | For European sales, request evidence related to REACH requirements; for the United States, verify applicable consumer-product and children’s-product requirements. | 13% |
| 4 | Fabric and Fiber Compatibility | Review the fiber content, yarn quality, fabric weight, elasticity, surface texture, and how these factors affect print clarity and durability. | Material specifications, yarn certificates, fabric test reports, and samples made with the proposed composition. | The supplier should clearly identify composition and construction and should not substitute materials without written approval. | 10% |
| 5 | Print Durability and Product Quality | Evaluate wash resistance, rubbing resistance, stretch recovery, dimensional stability, seam strength, and overall comfort. | Independent wash and abrasion test reports, internal inspection records, and samples tested under the buyer’s care instructions. | Approval should be based on test results from the final sock, not only on loose fabric or a digitally printed paper sample. | 15% |
| 6 | Quality Management System | Determine whether the factory controls incoming materials, artwork approval, in-process production, final inspection, corrective actions, and traceability. | Quality manual, inspection checklist, corrective-action records, audit reports, and certification details where applicable. | A documented inspection process and traceable batch records should be available for every production order. | 10% |
| 7 | Sampling and Artwork Service | Assess technical support for file preparation, repeat sampling, size grading, pattern placement, and approval management. | Artwork specification template, sampling procedure, revision records, and examples of approved technical files. | The factory should provide a physical pre-production sample and obtain written approval before starting bulk production. | 8% |
| 8 | Capacity, MOQ, and Lead Time | Compare minimum order quantity, sample turnaround, bulk production schedule, peak-season capacity, and the supplier’s ability to handle repeat orders. | Written quotation, production calendar, capacity statement, and references for comparable order volumes. | Choose a supplier whose confirmed MOQ and lead time match the project instead of relying on an unverified standard promise. | 7% |
| 9 | Export and Packaging Capability | Review export documentation, carton standards, labeling support, packaging customization, and experience with the destination market. | Commercial invoice template, packing list, carton details, labeling examples, and agreed Incoterms. | Packaging and labeling requirements should be confirmed in writing before production and checked during final inspection. | 5% |
| 10 | Communication and Commercial Reliability | Evaluate response speed, technical accuracy, transparency about subcontracting, payment terms, warranty policy, and handling of quality claims. | Signed quotation, production agreement, response records, quality-claim procedure, and clearly identified manufacturing locations. | Prefer suppliers that provide complete written answers, realistic schedules, transparent terms, and a defined remedy for nonconforming goods. | 5% |
