AI-Powered supplier vetting

SummaryHangzhou Xinjian Electronic Co., Ltd. is a limited company with 16 employees, two production lines, and a product focus on controllers and sensors. Its stated business scope covers industrial control equipment, IoT devices, software development, and related sales. The supplier holds ISO 9000 and ISO 9001 certifications and reports 11–20 years of R&D engineering experience and 6–10 quality-control staff. It provides OEM services for popular brands and has in-stock capacity, but no available SDK, overseas agents or branches, overseas warehouse, overseas showroom, or offline trade-show participation. Significant control gaps are indicated by the absence of written corrective/preventive-action and complaint-handling procedures, no stated quality assurance, and no valid manufacturing-capacity contract with associated subcontractors. Audit details are provided, but the evaluation result is recorded as 0 without an explanatory assessment.

Supplier typeThe supplier is identified as Hangzhou Xinjian Electronic Co., Ltd., a limited company with a combined company type and no stated group affiliation. Its scope includes industrial control equipment, IoT devices, software development, and related sales, while its primary offered products are controllers and sensors.

CertificationsThe supplier reports holding ISO 9000 and ISO 9001 management-system certifications. This is explicit evidence of certification holding, although the provided slices do not state certificate numbers, scope, or validity dates.

After-Sales capabilityAfter-sales support appears limited: there are no written corrective/preventive-action procedures or records and no written complaint-handling procedures or records. The supplier also has no overseas agents or branches, overseas warehouse, or overseas showroom, although it reports in-stock capacity and accepts FOB, CIF, CFR, and EXW quotation terms.

R&D capabilityThe supplier’s business scope includes R&D of distribution switch-control equipment, IoT technology, software development, and industrial automation systems. It reports 11–20 years of R&D engineer experience, but explicitly has no available SDK, so innovation capability is supported in some areas but not fully demonstrated.

Production capacityThe supplier operates two production lines, has 16 employees, reports in-stock capacity, and indicates a quality-control workforce of 6–10 people. However, it has no valid manufacturing-capacity contract with associated subcontractors and reports no quality assurance, creating explicit production-control deficiencies.

Customization capabilityThe supplier explicitly provides OEM services for popular brands, and its stated scope includes manufacturing and R&D of industrial control equipment, IoT devices, and related systems. These facts support customization or contract-manufacturing capability, although no specific customization examples or technical parameters are supplied.

Product Q&A

Q:What is the detection area of the smoke detector?

The detection area is not bigger than 80 square meters, depending on room height and roof slope.

Q:How do I install the smoke detector?

Drill two mounting holes 58mm apart on the ceiling, install expansion tubes, fix the base with screws, then align and rotate the detector clockwise to complete installation.

Q:What type of batteries does the detector use?

It uses No. 5 Mercury-Free Batteries (1500mAh/1.5V), with a total supply of DC 3V from 2 pieces.
