| Product Construction | Food-contact surfaces made from stainless steel suitable for the intended application; smooth, cleanable welds and rounded internal corners. | Material certificate, product drawings, weld photographs, internal-surface sample, and cleaning instructions. | 18% | Corrosion, hygiene problems, difficult cleaning, and shortened service life. |
| Capacity and Heating Performance | Commercial capacities commonly range from approximately 4 to 40 litres; heating output, thermostat range, and recovery time must match the application. | Rated capacity, usable capacity, wattage, temperature range, warm-up test, and heat-recovery test under load. | 15% | Slow service, uneven food temperature, excessive energy use, or overheating. |
| Electrical Configuration | Voltage, frequency, plug, grounding, insulation, and rated power must be configured for the destination market. | Rating label, wiring diagram, insulation test report, grounding test, plug specification, and destination-market sample. | 14% | Electrical shock, nuisance tripping, non-compliance, or inability to install the unit. |
| Food-Contact Compliance | Materials, coatings, seals, and lubricants should be documented as suitable for food-contact use in the target market. | Food-contact declarations, material composition, migration or safety test reports, and seal-material specifications. | 14% | Import delays, regulatory action, product withdrawal, or food-safety exposure. |
| Safety and Market Access | The supplier should identify applicable destination-market electrical and machinery requirements instead of relying on generic certificates. | Declaration of conformity where applicable, test reports, user manual, warning labels, and traceable model information. | 12% | Customs or marketplace rejection and increased product-liability risk. |
| Quality-Control System | Documented incoming-material checks, in-process inspection, electrical testing, functional testing, and final inspection. | Inspection checklist, sample quality records, calibration certificates, corrective-action records, and pre-shipment inspection procedure. | 10% | Inconsistent batches, hidden defects, higher return rates, and weak warranty support. |
| Customization Capability | Ability to adapt voltage, plug type, capacity, controls, labeling, packaging, and accessories without changing critical safety features. | Approved drawings, engineering change process, prototype sample, customization quotation, and sample approval record. | 8% | Specification mismatch, delayed launch, and unapproved product changes. |
| Commercial Terms | Quotation should clearly state unit price, tooling, packaging, minimum order quantity, payment milestones, warranty, and delivery terms. | Signed quotation, pro forma invoice, warranty terms, spare-parts list, Incoterms, and payment schedule. | 5% | Unexpected landed cost, payment disputes, and unclear after-sales obligations. |
| Production and Delivery Capability | Supplier should provide realistic production capacity, lead-time assumptions, packaging specifications, and shipment planning for repeat orders. | Factory audit, production schedule, packaging drop-test evidence, shipment history with redacted details, and capacity plan. | 4% | Late delivery, transit damage, stock shortages, or inability to scale orders. |
