AI-Powered supplier vetting
SummaryHaikou Haojinghui Industrial Co., Ltd. is identified as a China-based limited company operating as both a trading company and manufacturer/factory, with offices in Hainan and stated factory operations in Suzhou, Jiangsu. It focuses on electrical insulating materials, including polyimide film, adhesive tape, insulation paper, pressboard, laminate sheets, FR4/G10 materials, and related products. The supplier reports ISO 9001 certification, six production lines, 6–10 years of R&D engineer experience, and fewer than five quality-control staff. It has exported since 2013, with exports representing 71%–90% of total sales. The available records show limited transaction evidence involving one buyer in Mexico during 2025. Evidence is insufficient to establish after-sales service, financial credibility, or customization capability. Production capability is supported by stated facilities and product output information, although some reported production figures appear inconsistent and should be verified.
Supplier typeThe supplier is explicitly described as both a trading company and manufacturer/factory, with a stated focus on manufacturing and exporting electrical insulating materials. Its company description also reports multiple production departments and offices in several Chinese locations.
CertificationsThe supplier explicitly reports holding ISO 9001 certification for its management systems. No additional certifications, scope, issuing body, or validity period is provided.
Production capacityProduction capability is supported by six reported production lines, stated production departments, electrical insulating-material product coverage, and annual productivity information for polyimide film, tape, and adhesive tape. However, the reported output quantities are unusually large and should be verified before relying on them for capacity planning.
Client casesThe supplier reports that exports account for 71%–90% of total sales and that it began exporting in 2013. Trade records identify one buyer in Mexico and four recorded transactions across two 2025 entries, but the evidence is limited and does not establish a broad or independently verified customer portfolio.
