| 1 | Substrate and Product Definition | Confirm whether the product is UV-coated MDF, particleboard, plywood, PVC foam board, or another substrate. Specify the core, surface finish, intended use, and applicable side or sides of coating. | Product specification sheet identifying the substrate, construction, finish, and intended application. | “UV board” can refer to different board materials and finishes; products should be compared only when their construction and intended use are comparable. |
| 2 | Dimensions and Tolerances | Review available length, width, thickness, flatness, squareness, and the tolerances offered for the exact product. | Written dimensional specification and inspection records for a production batch. | Dimensional consistency affects cutting, edge finishing, installation, and compatibility with downstream equipment. |
| 3 | Surface Finish and Appearance | Assess gloss level, color consistency, texture, coating coverage, and visible defects under agreed inspection conditions. | Approved reference sample, finish details, and documented visual-inspection criteria. | Clear acceptance criteria reduce disputes over color variation, scratches, pinholes, and other appearance issues. |
| 4 | Coating Performance | Identify the coating system and request test results relevant to the intended environment, such as adhesion, surface hardness, or resistance to specified household chemicals. | Test reports that state the method, sample details, and results; confirm that claims apply to the same product construction. | Performance depends on the coating, substrate, and test method. Results are meaningful when they match the buyer’s use conditions. |
| 5 | Indoor-Air and Chemical Compliance | Check the requirements of the destination market and the product’s intended use, including applicable emissions or chemical restrictions. | Current third-party test reports or declarations identifying the tested product, standard, and scope. | Requirements vary by market and substrate; a general claim of compliance is not a substitute for product-specific documentation. |
| 6 | Quality Control and Traceability | Ask how incoming materials, coating operations, finished boards, and nonconforming products are controlled and recorded. | Quality-control procedure, sample inspection record, batch identification method, and corrective-action process. | Documented controls help buyers trace issues to a shipment or production batch and assess consistency over repeat orders. |
| 7 | Production Capacity and Lead Time | Confirm capacity for the required specifications, order quantity, production schedule, and repeat-order planning. | Written production plan, quoted lead time, and confirmation of the requested specifications and quantity. | Capacity and scheduling should be assessed against the buyer’s actual order profile rather than broad, unverified claims. |
| 8 | Packaging and Transport Protection | Review protection against moisture, impact, abrasion, and edge damage during storage and transit; confirm packing dimensions and container loading plan. | Packaging specification, packing photographs or sample, and shipment inspection checklist. | Appropriate packaging helps reduce transit damage and supports efficient handling at the destination. |
| 9 | Export Documentation and Market Readiness | Verify the supplier can provide accurate commercial and shipping documents and any product documentation required for the destination market. | Sample invoice, packing list, product specification, and relevant compliance documents with sensitive information removed. | Complete, consistent documentation supports customs clearance and helps buyers check that shipped goods match the order. |
| 10 | Quotation, Samples, and After-Sales Support | Compare quotations on the same basis, including specification, quantity, packaging, delivery terms, and payment terms. Confirm the sample-approval and complaint-handling process. | Itemized quotation, pre-production or approval sample, written order terms, and documented claim-resolution procedure. | A like-for-like quotation and clear support process make supplier comparisons more reliable and help manage quality issues. |
