| Sample Testing | Kit completeness | Confirm that the shipment includes the required banding tool, tensioning or sealing components, buckles or seals, replacement parts, and operating instructions. | The sample should match the agreed bill of materials and packaging specification. | Missing components, unclear accessories, or inconsistent packing lists. | 0–5 |
| Sample Testing | Material verification | Check the stated strap material, strap width, strap thickness, seal or buckle material, and visible surface quality against the quotation and sample label. | Material and dimensions should be documented and consistent across the sample, specification sheet, and commercial quotation. | Unlabeled materials, vague descriptions such as “high quality,” or unexplained substitutions. | 0–5 |
| Sample Testing | Operational performance | Use the kit on the intended pallet load and check tensioning, sealing, cutting, handling comfort, and load stability during normal packing operations. | The kit should complete the stated application without slippage, broken seals, damaged straps, or unsafe handling conditions. | The supplier refuses a practical trial or provides no operating guidance. | 0–5 |
| Sample Testing | Repeatability | Run repeated packing cycles using samples from more than one production batch when available, then compare seal quality and strap tension. | Results should remain consistent under the same operating method and load conditions. | Large variation between samples or a request to test only one hand-picked unit. | 0–5 |
| Factory Audit | Business identity | Verify the legal entity, registered address, production location, export authorization where applicable, and consistency between documents and the physical facility. | Company registration, quotation, bank information, and factory location should be consistent and independently verifiable. | Payment requested to an unrelated entity or an unexplained mismatch between documents and factory address. | 0–5 |
| Factory Audit | Quality management | Review incoming-material inspection, in-process checks, final inspection records, nonconformity handling, and corrective-action procedures. | Inspection records should identify specifications, inspection results, dates, responsible personnel, and corrective actions. | No traceable records, undocumented rework, or quality decisions based only on visual judgment. | 0–5 |
| Factory Audit | Production capacity | Assess equipment, staffing, production flow, storage conditions, maintenance practices, and the ability to support the requested order volume. | Observed capacity should be compatible with the required quantity, delivery schedule, and expected peak demand. | Heavy reliance on undisclosed subcontractors or no capacity plan for repeat orders. | 0–5 |
| Factory Audit | Traceability | Check whether raw materials, finished kits, packaging labels, inspection results, and shipment records can be linked by batch or order number. | A sample order should be traceable from incoming material through production, inspection, and dispatch. | Products are mixed without batch records or labels cannot be linked to inspection data. | 0–5 |
| Factory Audit | Packaging and export readiness | Review carton strength, moisture protection, palletization, shipping marks, spare-part packing, and export documentation procedures. | Packaging should protect metal and plastic components from impact, corrosion, moisture, and loss during transportation. | No packaging specification, weak cartons, or incomplete shipping documentation. | 0–5 |
| Customer Reviews | Review authenticity | Compare reviews across independent business platforms, trade references, customer testimonials, and transaction history where available. | Positive feedback should be supported by specific details about product quality, delivery, communication, and after-sales handling. | Only anonymous testimonials, duplicated wording, or reviews with no product or order context. | 0–5 |
| Customer Reviews | Recency and consistency | Review feedback from recent transactions and compare recurring comments about quality consistency, lead time, packaging, and complaint resolution. | Recent reviews should show a consistent service pattern rather than relying only on old ratings. | Recent complaints about delayed delivery, changing specifications, or unresolved quality issues. | 0–5 |
| Commercial Reliability | Quotation clarity | Check whether the quotation clearly states product specifications, quantity, packaging, tooling, spare parts, shipping terms, payment terms, and validity period. | All commercial assumptions should be written in one consistent quotation or purchase specification. | Frequent price changes, hidden charges, or important terms communicated only verbally. | 0–5 |
| Commercial Reliability | Lead-time control | Verify production lead time, sample lead time, shipping preparation time, and the supplier’s process for notifying delays. | The supplier should provide a written production schedule and identify milestones that can be monitored. | Unconditional promises without a production plan or repeated changes after order confirmation. | 0–5 |
| After-Sales Support | Complaint response | Ask how the supplier handles defective kits, missing components, replacement parts, photographic evidence, root-cause analysis, and corrective action. | The procedure should define response responsibility, evidence requirements, replacement or credit options, and target response times. | No written procedure or refusal to accept responsibility for verified defects. | 0–5 |
| Final Decision | Weighted supplier score | Combine sample results, audit findings, review evidence, commercial performance, and after-sales capability before placing a large order. | Use a documented scoring system; require critical quality and traceability items to pass independently of the total score. | Selecting solely on the lowest price or overall rating without checking critical failure points. | /75 |
