For factories

For manufacturers

A profile is an editorial record, not an advertisement. Being listed does not mean being endorsed, and a request can be declined when the underlying documents cannot be checked.

What we ask for

1. The Chinese registered legal name and unified social credit code.
2. The address of the site that will actually produce the boards.
3. Capability tables by product series, not a single company-wide maximum.
4. UL file numbers with the certificate holder name.
5. A written statement of which process steps are subcontracted.
6. Permit records for the production site where applicable.

How a request is handled

We check each item against a primary source, assign an evidence level, and record the review date. Claims that cannot be checked are published as manufacturer reported or left unconfirmed. We do not present an unverified capability as a qualification.

Grounds for declining or removing a profile

• The registered entity and the production site cannot be matched.
• Certificate numbers cannot be found in the issuing database.
• The same production site is submitted under several legal entities to gain extra pages.
• Capability figures are merged across unrelated product series after being asked not to.

Corrections are welcome at any time. Send the profile URL, the field and a primary source through the channel on the about page. For the reasoning behind each label, see how we verify.
