| 1 | Product Specification Capability | Confirm whether the factory can produce the required substrate, thickness, width, core size, coating, and reel diameter. | The supplier should provide a written specification sheet covering tolerances, core dimensions, roll length, and applicable grades. | Technical datasheet, approved sample, and signed product specification. |
| 2 | Raw Material Traceability | Check how base paper, film, foil, adhesive, ink, and coating materials are approved and recorded. | Each production batch should be linked to incoming-material records and a finished-goods lot number. | Material certificates, batch records, and lot-tracking procedure. |
| 3 | Production Capacity | Evaluate available converting, slitting, rewinding, printing, laminating, and packing capacity for recurring orders. | Capacity should be demonstrated using current equipment lists, monthly output records, and realistic lead-time commitments. | Factory audit, machine list, production schedule, and capacity statement. |
| 4 | Quality Management System | Review inspection procedures for incoming materials, in-process production, finished reels, and nonconforming products. | A documented quality system should define inspection frequency, acceptance limits, corrective action, and record retention. | Quality manual, inspection checklist, calibration records, and corrective-action reports. |
| 5 | Dimensional and Visual Consistency | Verify web width, thickness, winding tension, roll hardness, edge quality, splice control, surface defects, and telescoping. | Acceptance limits must be agreed before production and measured with calibrated instruments. | Pre-production sample, inspection report, photos, and measurement data. |
| 6 | Testing and Compliance | Identify tests relevant to the application, including tensile strength, moisture, adhesion, coefficient of friction, migration, or barrier performance. | Test methods should match the intended end use and the destination-market regulations. | Third-party laboratory reports, declarations of conformity, and test-method references. |
| 7 | Lead Time and Order Flexibility | Compare sampling time, standard production lead time, minimum order quantity, rush-order policy, and changeover flexibility. | Lead times should be quoted by product type and confirmed in a purchase agreement rather than stated generally. | Formal quotation, production plan, delivery history, and service-level terms. |
| 8 | Packaging and Export Logistics | Check moisture protection, pallet strength, edge protection, labeling, container loading, and documentation capability. | Packaging should protect reels from deformation, contamination, and humidity during international transport. | Packaging specification, loading photographs, shipping documents, and carton or pallet markings. |
| 9 | Total Cost of Ownership | Compare material price, tooling, setup fees, packaging, freight, duties, waste rate, inspection costs, and payment terms. | The lowest quoted unit price should not be selected without reviewing yield, defect risk, logistics, and after-sales costs. | Itemized quotation, landed-cost model, payment terms, and warranty conditions. |
| 10 | Communication and After-Sales Support | Assess technical communication, response speed, complaint handling, replacement policy, and support for future specification changes. | Responsibilities, response times, inspection procedures, and claim-resolution steps should be written into the contract. | Communication log, service agreement, complaint procedure, and warranty terms. |
