Portable display export certification and 5-stage pre-shipment QC specifications

1. Global market compliance and certification coverage

All models undergo formal type tests at CNAS/CMA accredited laboratories, securing compliance certificates for major global economies. Official test reports are ready for direct submission to customs and Amazon/marketplace compliance portals.

• China market: Mandatory CCC certification fully maintained
• European Union & UK: CE marking (EMC Directive & LVD Safety Directive) and RoHS 2.0 (10 hazardous substance environmental directives)
• North American market: FCC Part 15B Class B digital device certification for residential and commercial electromagnetic compliance
• Japanese market: PSE compliance (Diamond PSE power supplies and Round PSE device conformance)

2. Third-party testing and factory audit credentials

Beyond product safety certificates, Shenzhen Xinshengli Technology Co., Ltd. has successfully passed rigorous on-site factory audits by premier international inspection bodies.

• Intertek verified: Formally audited and certified for production capability and quality assurance systems
• SGS audited: On-site verification of 2,000 m² facilities, automated machinery, and workforce registers
• Alibaba Verified Supplier: On-site verified corporate entity, verified manufacturing lines, and capacity audits

3. Five-stage 100% pre-shipment quality control (QC)

We enforce 100% full-unit inspection at every critical step rather than statistical sampling. 15 dedicated QC engineers manage quality gates to ensure an ex-factory pass rate exceeding 99.5%.

• Stage 1 · Incoming QC (IQC): A-grade panel defect grading (zero dead pixels), SMD board electrical testing, and CNC casing surface finish audits
• Stage 2 · In-process QC (IPQC): Hourly assembly line process checks, anti-static wristband monitors, torque wrench calibration, and thermal pad placements
• Stage 3 · Semi-finished interface test: Comprehensive 4K signal generator tests across HDMI, Type-C ports, audio jacks, speakers, and OSD response
• Stage 4 · High-temperature burn-in test: 100% of manufactured units enter the aging room for at least 4 hours of continuous power-on display cycling
• Stage 5 · Out-going QC (OQC): Clean-room wipe-down, screen film application, serial barcode validation, accessory testing, drop tests, and moisture-sealed carton packing

4. Complete audit documentation supplied to buyers

• Corporate credentials: Business license, 2,000 m² factory lease contracts, and manufacturing registrations
• Certificate packages: Full English test reports and certificates for CCC, CE-EMC, CE-LVD, RoHS, and FCC
• Audit reports: Complete unredacted factory audit PDF reports from Intertek and SGS
• Factory media: High-definition video walkthroughs of automated lines, manual assembly, and the burn-in chamber
• Engineering datasheets: Mechanical dimensional drawings, circuit block diagrams, and interface pinout sheets

5. Manufacturing infrastructure behind quality delivery

• 2,000 m² manufacturing plant equipped with ESD flooring and partitioned dust-proof clean zones
• Two modern automated assembly lines with monthly capacity exceeding 100,000 units
• A team of 80+ professionals, including 10 dedicated R&D engineers and 15 full-time QC specialists
• Strong engineering pipeline releasing 5 new proprietary tooling designs every month
• Global footprint exporting to over 100 countries and regions worldwide
