| 1 | Laser safety and product classification | IEC 60825-1 alignment | Request the laser product classification, wavelength and output-power information, user instructions, warning labels, and applicable test reports. IEC 60825-1 is the international safety standard commonly used for laser products. | Incorrect classification or missing warnings can create eye-safety risks, import delays, and compliance problems in the destination market. |
| 2 | Quality-management system | Documented quality controls | Check whether the factory has a current ISO 9001 certificate issued by an accredited certification body, documented incoming inspection, in-process inspection, final inspection, and corrective-action records. | A formal quality system improves batch consistency and makes recurring defects easier to trace and correct. |
| 3 | Optical and electrical performance consistency | Measured, not only promised | Ask for production test records covering output power, beam pattern, scanning angle, modulation response, operating temperature, input voltage, and unit-to-unit variation. | Unverified performance may lead to unstable projections, visible color differences, excessive heat, or premature product failure. |
| 4 | Environmental protection and durability | Application-matched IP rating | Confirm the declared IP rating and request the relevant test report. For outdoor installations, also check corrosion protection, cooling design, cable sealing, temperature range, and vibration or transport testing. | A product designed only for indoor use may suffer water ingress, corrosion, overheating, or electrical faults outdoors. |
| 5 | Regulatory and material compliance | Market-specific documentation | Verify applicable EMC, electrical-safety, RoHS, REACH, or other destination-market requirements. Request test reports that identify the exact model, revision, and tested configuration. | Generic or mismatched certificates may not support customs clearance, marketplace listing, or legal sale in the target country. |
| 6 | Manufacturing capacity and supply continuity | Capacity supported by records | Evaluate production equipment, assembly and aging-test areas, staffing, normal lead time, minimum order quantity, monthly capacity, component sourcing, and a documented plan for handling shortages. | Insufficient capacity or single-source components can cause missed launch dates, inconsistent components, and unexpected price changes. |
| 7 | After-sales support and customization | Written service terms | Confirm warranty duration, spare-parts policy, repair or replacement procedure, response time, firmware-support process, packaging options, OEM/ODM capability, and pre-shipment sample approval. | Clear service terms reduce downtime and provide practical protection when a batch contains defects or requires project-specific modifications. |
