AI-Powered supplier vetting

SummaryThe supplier demonstrates established manufacturing and OEM capabilities, with a 60,000 m² factory, more than 550 production staff, and stated monthly capacity of up to 144,000 KVAh. It supports multiple customization models and has documented procedures for supplier-service assessment, corrective actions, and customer complaints. Certifications and compliance evidence includes ISO9001:2015, RoHS, and company-stated ISO14001, OHSAS18001, UL, and CE qualifications. Export activity is material, with 51%–70% of sales from exports and seven years of export experience. However, the supplier has no available SDK, only two R&D engineers, no overseas warehouse, showroom, agents or branches, and no offline trade-show participation. Financial information is limited to year labels without performance figures, preventing a substantive financial assessment. OEM service for popular brands is explicitly confirmed, while collaboration with Fortune 500 companies is explicitly denied.

Supplier typeThe supplier is a manufacturing-oriented company with a stated production scope and a 60,000 m² factory employing more than 550 production staff. Its stated monthly production capacity reaches up to 144,000 KVAh, indicating an industrial manufacturer rather than only a trading or service intermediary.

CertificationsThe supplier explicitly reports ISO9001:2015 and RoHS certification, while its company description also states ISO14001, OHSAS18001, UL, and CE qualifications and compliance with several IEC standards. The available evidence supports a broad certification and product-compliance profile.

After-Sales capabilityThe supplier has written and followed procedures for customer complaints, corrective and preventive actions, and service-capability assessment. However, it reports no overseas warehouse, showroom, agent, branch, or overseas-service country coverage, so documented service processes exist but international local support is limited.

R&D capabilityThe supplier has two R&D engineers and reports production experience, but explicitly has no available SDK. The provided information does not demonstrate strong product-development, software-integration, or advanced innovation capability.

Production capacityThe supplier reports a 60,000 m² manufacturing facility, more than 550 production staff, and capacity of up to 144,000 KVAh per month. It also states that finished-product inspection instructions are uniformly followed and that average lead time is one month in both peak and off-season.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization, and reports more than 16 years of OEM experience for customer-oriented cooperation. OEM service for popular brands is also explicitly confirmed.

Client casesThe supplier confirms OEM service for well-known brands and states more than 16 years of OEM experience, providing evidence of brand-oriented customer work. However, it explicitly reports no collaboration with Fortune 500 companies and provides no named customer cases, so the breadth and quality of customer references cannot be fully assessed.
