AI-Powered supplier vetting

SummaryGAOSI MAGNET is described as a China-based manufacturer of permanent magnets, flexible rubber magnets, and magnetic assemblies, with stated annual magnet capacity of 5,000 tons and export experience of seven years. It reports multiple management-system certifications, including BSCI, ISO 14001, ISO 9001, GMP, and QC 080000. The supplier offers extensive customization, including sample-, design-, full-, minor-, and flexible-customization services. However, the evidence identifies limitations in formal technical development: it is not classified as a professional technical supplier, provides no 3D software design services, and has no available SDK. Service-control procedures exist but lack written records, while quality assurance status is unknown. The supplier has inventory capability but no overseas warehouse or showroom. Financial records are referenced for 2021–2023, but the provided information does not establish financial strength. No customer cases are provided.

Supplier typeThe supplier is identified as GAOSI MAGNET, a China-based manufacturer of permanent magnets, flexible rubber magnets, and magnetic assemblies. It is a limited company offering magnetic products and is not indicated to be part of a larger company group.

CertificationsThe supplier reports holding BSCI, ISO 14001, ISO 9001, GMP, and QC 080000 certifications. These stated certifications provide explicit evidence of formal management-system coverage across quality, environmental, social, manufacturing, and hazardous-substance-related areas.

R&D capabilityThe company describes innovation, technical personnel, advanced equipment, and 6–10 years of total R&D-engineer experience. Nevertheless, it is explicitly not classified as a professional technical supplier, offers no 3D software design services, and has no available SDK, indicating that formal advanced-development capability is limited or not demonstrated.

Production capacityThe supplier reports annual magnet productivity and output of 5,000 tons, has inventory capability, and describes itself as a manufacturer with German and Japanese production and testing equipment. A valid manufacturing-capacity contract is not established, but the stated production scale provides explicit evidence of manufacturing capability.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also states that its sales and factory teams provide OEM and ODM solutions, directly supporting broad customization capability.

Product Q&A

Q:What is the difference between isotropic and anisotropic ferrite magnets?

Isotropic magnets have the same magnetic properties in all directions and can be magnetized in any pole arrangement. Anisotropic magnets are oriented during production, have higher magnetic strength, but can only be magnetized in the direction of orientation.

Q:What materials are used to make these magnets?

The magnets are made from SrO or BaO and Fe2O3 using ceramic processing technology.

Q:What manufacturing processes are available?

Two processes are available: Dry process (produces both isotropic and anisotropic magnets with easy tool changes) and Wet process (produces only anisotropic magnets with higher tooling charges).

Q:What certifications do the magnets have?

The magnets are certified with RoHS, CE, and ISO9001.

Q:What are the payment terms?

Payment terms include T/T, D/P, and PayPal.
