Confirm the actual producer
Ask which site makes the quoted part and which steps happen there. A company profile or product listing does not prove that it presses, sinters, or machines the magnet itself.
B2B supplier screening
Barium Ferrite Magnet Company Evaluator
Compare the supplier evidence your project needs, then turn the result into a clear RFQ. The screen is a starting point; it does not verify a company, certificate, or product.
Choose the closest match and evaluate to see the evidence to request from your shortlisted supplier.
FerriteCustom accepts barium ferrite RFQs. This is not a market-wide company directory or proof that a requested grade or geometry is made in-house. Ask us to confirm the production site, tooling scope, and lot evidence for your drawing. For product-fit context, see our anisotropic barium ferrite fit checker.
Key conclusions
Choose on evidence, not the supplier label
Put tooling and handoffs in writing
Record who owns, stores, maintains, and may modify a tool. For a sourced order, identify the production site and how specifications, changes, and lot records reach it.
Match quality evidence to the part
Verify a certificate against its issuer, site, scope, and validity. Separately agree the inspection data, customer approval, and change-control evidence required for the magnet.
Keep compliance product-specific
A substance record or generic declaration does not establish compliance for every finished component. Request current documents for the exact grade, finish, market, and customer requirements.
Factory or trading company: evidence to compare
Either route can work. The useful comparison is how clearly the supplier identifies the production site, controls the handoff, and supports your quality and delivery requirements. The table is a request checklist, not a claim that every company in either category works the same way.
| Question | Direct manufacturer | Trading company / sourcing partner | Evidence to request |
|---|---|---|---|
| Who makes the quoted part? | Confirm the legal name and address of the site performing the relevant production steps. | Request the actual production site and how it is selected, monitored, and disclosed. | Site details, process map, and permission for a quality review. |
| Who controls the tooling? | Put ownership, storage, maintenance, modification cost, and return terms in writing. | Identify which sub-tier owns and stores the tool, and make the same terms contractually clear. | Tooling quotation and ownership / maintenance terms. |
| How is product quality documented? | Request the applicable quality-system scope, sample inspection, batch traceability, and change control. | Ask how requirements and lot records move between the sourcing company and production site. | Current certificate for the named site, inspection plan, sample report, and lot record. |
| What sets cost and delivery? | Ask for separate tooling, sample, production, inspection, and shipment assumptions. | Request the same breakdown, including any service, consolidation, or sub-tier charges. | A dated quote for the same drawing, quantity, Incoterm, and inspection scope. |
| What compliance evidence applies? | Request documents for the exact grade, finish, destination market, and customer restricted-substance list. | Confirm documents are traceable to the actual producer and quoted item, not a generic catalog family. | Current declaration, test report where required, and product-specific safety data. |

Risks and limits
Certificate or site mismatch
Check the issuer, covered production site, scope, and validity. Then confirm the customer approval requirements for this part; a certificate alone is not part approval.
Unclear tooling or sub-tier control
Define tooling ownership, custody, maintenance, change approval, and access to production records before placing a custom order.
Compliance assumptions
Do not treat REACH registration or a material name as a finished-part declaration. Request current supplier documents for the item and destination. For powder handling or machining, review the exact product safety data and applicable workplace controls.
Grade and temperature fit
Magnetic performance and low-temperature loss depend on grade, geometry, and circuit operating point. Request the proposed grade's temperature-dependent B-H curve and assess it against the actual application.

FAQ
Questions buyers ask before shortlisting
How can I verify that a company manufactures barium ferrite magnets?
Ask for the legal name and address of the production site, a process map for the quoted part, and evidence for the steps it says it performs. If a trading company is involved, ask it to identify the actual producer and explain how production changes and lot traceability are controlled.
Is buying direct from a factory always the better option?
No. A distributor or trading company can be useful for stocked items, consolidated orders, or procurement support. Compare the actual production-site evidence, technical response, traceability, service scope, total quote, and your ability to audit or resolve quality issues.
What should I include in a barium ferrite magnet RFQ?
Include a controlled drawing, named material or grade requirement, dimensions and tolerances, magnetization direction, annual forecast and release quantity, inspection and test requirements, destination market, packaging, and required compliance documents. Mark unknowns for supplier clarification.
Does an IATF 16949 certificate prove the magnet is approved?
No. Verify the certificate issuer, site, scope, and validity, then confirm the customer-specific approval path and required PPAP submission for the part. A quality-system certificate does not by itself approve a particular magnet or replace customer requirements.
Can I assume a barium ferrite magnet is RoHS or REACH compliant?
No. Do not infer finished-part compliance from the material name or a general substance registration. Request current documents for the exact grade, any coating or finish, destination market, and customer restricted-substance requirements.
What lead time or price should I expect?
There is no reliable universal figure for every grade, geometry, tooling status, quantity, and inspection scope. Ask suppliers to separate tooling, sample approval, production, and transport timing and quote the same controlled requirements.
What should I check for low-temperature use?
Request temperature-dependent B-H data for the proposed grade and assess it with the magnet geometry and magnetic circuit. Ferrite coercivity changes with temperature, and irreversible loss depends on the operating point; a single temperature threshold is not a substitute for the supplier curve and application review.

- European Commission overview of REACH describes chemical-substance registration and risk information duties; it does not establish compliance for an arbitrary finished magnet.
- Directive 2011/65/EU (RoHS) on EUR-Lex sets restricted-substance limits by weight in homogeneous materials. Check scope, amendments, exemptions, and exact product evidence.
- Tokyo Ferrite's low-temperature technical note shows how the permeance coefficient and ferrite B-H curve affect irreversible demagnetization; the example is not a universal cutoff.
- AIAG's Production Part Approval Process overview describes part-specific approval requirements. Check the IATF customer-specific requirements for the applicable customer and program.
