About Cardinal

Magnet sourcing starts with the grade and the real delivery path.

Cardinal Magnetics is an independent sourcing service for industrial buyers of custom magnets and magnetic components. It exists for one problem: custom-magnet quotations become misleading when grade composition, manufacturing origin and export timing are treated as footnotes.

I founded Cardinal Magnetics after researching how grade composition, export approval and named manufacturing capacity can change an industrial magnet sourcing decision. I help you structure the request and compare the evidence; I do not manufacture components, approve your engineering specification or qualify suppliers for you.

The problem I am organizing around

Since April 2025, China has required non-automatic export licences for SmCo magnets and for NdFeB magnets containing dysprosium or terbium. Applications frequently remain unresolved for 60–120 days or longer, with no statutory review period. A supplier can therefore quote a credible factory production time while the actual export date remains uncertain. I start the comparison by separating those timelines and identifying which grade or composition creates the exposure.

The sourcing evidence

A useful alternative-supply discussion needs names, status and dates rather than a long directory. My current research map records Neo Performance Materials in Narva with an initial 2,000-tonne annual objective, Noveon Magnetics in the United States, Vacuumschmelze building in Sumter, TDK and Shin-Etsu in Japan, and planned SGI Vina capacity in Vietnam. These are publicly identified potential manufacturing sources, not contracted suppliers or promises of availability.

The RFQ method

Potential sources should answer the same question. I structure the geometry, dimensions, tolerance basis, grade or operating temperature, coating, magnetization, prototype and annual quantities, origin definition and target delivery date. A drawing helps but is not required to start. I keep production time, licensing, export, freight and commercial validity as separate assumptions. Supplier deviations remain visible instead of being folded into an apparently lower unit price.

Role and decision ownership

I structure your sourcing questions, identify potential options and organize responses. You retain engineering approval, compliance review, supplier qualification and the purchasing decision; potential manufacturers remain responsible for their technical data, quotations and production statements. I state this boundary here so the rest of the site can focus on the practical value of a clearer grade, origin and delivery comparison.

There is no sourcing fee for you. Cardinal is paid a commission by the selected manufacturer if an introduced project results in paid business. Options are organized around fit with your requirement, not commission level.

Method

From drawing to comparable quotations.

Technical magnet RFQs are difficult to compare when specifications, origin requirements and qualification evidence vary by supplier. I organize the request before approaching potential manufacturing sources.

Structure the RFQ

I capture geometry, grade, coating, magnetization, tolerances, volumes and application constraints.

Identify options

I research potential manufacturing sources aligned with the technical request and preferred origin.

Make quotes comparable

I organize supplier responses so you can see commercial and technical differences before you decide.

Operating principles

A sourcing file built around evidence.

I structure technical RFQs, identify potential manufacturing options and make supplier responses easier to compare.

Your grade and composition exposure made explicit
Named capacity recorded with status and date
Your origin requirements written into the RFQ
Supplier deviations preserved for your decision
