| Product safety and design | 20% | Clear intended-use guidance, stated capacity limits, stable construction, and accessible inflation and deflation instructions. | Product drawings, user instructions, capacity rationale, and test reports relevant to the destination market and intended use. | Unsubstantiated safety claims, missing instructions, or capacity figures with no supporting explanation. |
| Materials and construction | 18% | Specific material descriptions, consistent material thickness specifications, secure seams, suitable valves, and a defined repair approach. | Material specification sheet, seam-construction details, valve information, sample inspection, and repair-kit contents. | Vague descriptions such as “premium PVC” without specifications, or unwillingness to identify construction methods. |
| Quality control | 17% | Documented incoming-material, in-process, and final inspection procedures, including checks for leaks and visible defects. | Quality-control checklist, inspection records for a sample order, defect-handling procedure, and pre-shipment inspection terms. | Only verbal assurances, no inspection records, or unclear responsibility for defective units. |
| Compliance and documentation | 15% | Accurate, product-specific documentation and willingness to clarify which requirements apply to the product and destination. | Reports and certificates that can be checked for product scope, issuing organization, date, and applicable market requirements. | Certificates for unrelated products, unverifiable documents, or promises of universal compliance without details. |
| Customization capability | 10% | Clearly defined options for dimensions, colors, graphics, accessories, packaging, and sample approval. | Written specification, artwork proof, sample process, tooling or setup charges, and confirmation of change-control procedures. | Unclear customization limits, no approval sample, or differences between approved artwork and production specifications. |
| Production and delivery planning | 8% | A written production schedule with defined milestones and communication about shipping terms and delivery assumptions. | Order timeline, production status updates, packing details, and a quotation identifying the shipping term and destination basis. | Guaranteed delivery dates without stated assumptions, or quotations that omit important logistics costs. |
| Order terms and after-sales support | 7% | Transparent payment, sample, warranty, spare-parts, complaint, and replacement terms agreed before production. | Pro forma invoice, written warranty policy, claims process, and response-time expectations. | Important terms left to verbal discussion or no defined process for handling product issues. |
| Supplier verification and communication | 5% | Consistent company and factory details, knowledgeable answers, and a verifiable manufacturing or sourcing arrangement. | Business registration details, factory or production-capability evidence, references where available, and a video or in-person audit. | Inconsistent business information, evasive answers, or refusal to clarify whether the supplier is a manufacturer or trading company. |
