AI-Powered supplier vetting

SummaryGuangzhou Hongyu Magnetoelectric Co., LTD is identified as a China-based manufacturer/factory specializing in magnets and magnetic components, particularly sintered neodymium iron boron. The supplier reports ISO 9001, ISO 14001, and ISO 45001 certifications, five production lines, annual sintered neodymium iron boron productivity of 800 tons, and 11–20 R&D engineers and quality-control staff. It describes micron-level processing, complex-specification customization, electroplated coatings, and full-process quality control. Export activity is reported across multiple global regions, although the stated export start date is 2025-12-26 and export sales account for 21%–30%. The available information does not substantiate after-sales performance or specific customer cases. Financial credibility cannot be assessed because no non-financial evidence sufficient for that judgment is provided.

Supplier typeThe supplier is explicitly classified as a Manufacturer/Factory and operates as a limited company in Guangzhou, Guangdong, China. Its stated commercial focus is Metallurgy, Mineral & Energy, consistent with its magnetic-materials business.

CertificationsThe supplier states that it holds ISO 9001 and ISO 45001 certifications, while another profile lists ISO 9001 and ISO 14001. This provides explicit evidence of multiple management-system certifications, although the slices do not clarify certification scope or validity dates.

R&D capabilityThe supplier reports 11–20 years of R&D engineer experience and describes core processes including rapid-solidification flanging and vacuum sintering for high-performance neodymium iron boron materials. These statements support relevant technical development capability, but no patent, laboratory, or independently verified innovation evidence is provided.

Production capacityThe supplier reports 800 tons of annual productivity for sintered neodymium iron boron, five production lines, and lead times of within 15 working days off-peak and one month during peak season. It also reports exports to multiple global regions, providing explicit evidence of established production and fulfillment capability.

Customization capabilityThe supplier explicitly claims micron-level processing, customization of complex specifications, electroplated coating for weather resistance and stability, and customized solutions across multiple fields. Its product range includes neodymium, AlNiCo, and ferrite magnets, supporting a broad stated customization offering.
