AI-Powered supplier vetting

SummaryZHUHAI EASTEVER ELECTRONIC CO., LTD. is a Chinese manufacturing factory established in 2010, with 27 employees and operations in Zhuhai, Guangdong. It produces RF transformers, baluns, power splitters, couplers, inductors, attenuators, and diplex filters. The supplier reports export activity since 2010, with exports representing 41%–50% of sales, and lists relationships with several recognized domestic and international companies. It reports production bases in multiple Chinese locations and claims ISO9001:2004, ISO14001:2004, SGS, and EU RoHS-related compliance; however, the provided audit result is coded as 0 and the audit details are not explained. Information on after-sales services, financial credibility, innovation, customization, and several operational capabilities is insufficient or marked unknown.

Supplier typeThe supplier is explicitly identified as a manufacturing factory and a limited company located in Zhuhai, Guangdong, China. Its associated-company industry is manufacturing, supporting classification as a direct manufacturer rather than a trading-only entity.

CertificationsThe supplier states that its production plant has ISO9001:2004 and ISO14001:2004 certification, and that production links passed SGS and comply with EU RoHS. However, the provided SGS report validity ended on 2025-01-28, and the audit result is coded as 0 without interpretation, so current certification status is not fully verifiable.

Production capacityThe supplier reports annual productivity for passive RF balun transformers of 300,000 pieces and identifies production bases in Yangjiang, Sichuan, and Mianyang. Its established relationships with cable-TV equipment companies and listed enterprises further support operational experience, although capacity figures for several other products are incomplete.

Client casesThe supplier lists stable cooperative relationships with American Arris, CASA, Malaysia Inte, Foxconn, Digital Video News, Kant, Core Tong, Dongfang Guangzhou, SKYWORTH, Jiuzhou, and other cable-TV terminal equipment companies. These named relationships provide explicit evidence of customer experience, while the export history since 2010 and 41%–50% export-sales share indicate international commercial exposure.
