Editorial Policy, Data Sources & Verification

• Official manufacturer websites, catalogues, and documents published by the company.
• Business registration records and public certification databases when accessible.
• Manufacturer-submitted profile information and correction requests.
• Editorial research used to explain common products, components, processes, materials, and applications.

A source being public does not make every claim current or accurate. CNFX records should be checked against the named primary source.

• Published: The record is available on CNFX but may not have completed source review.
• Source reviewed: An editor checked that the cited source supports the specific field at the time of review.
• Manufacturer submitted: The company or its representative supplied the information; this is not independent verification.
• Unverified: Evidence was unavailable, incomplete, outdated, or not independently checked.

The word “verified” should only describe a specific checked field or source. It does not mean CNFX has audited the factory or certified the business as a whole.

When CNFX links a manufacturer to a product, the link must rest on a page of that company’s own website where the product is listed. The manufacturer card on the product page shows the wording used on the company’s own site, a direct link to that page, and the date we last checked it. Outbound links carry nofollow — they are citations, not endorsements.

• Same domain. The evidence URL must be on the company’s own website. Marketplace storefronts and third-party directory listings are not accepted as evidence of manufacture.
• Page read, not just status code. We fetch the page and confirm the product appears on it. An HTTP 200 alone is not evidence — a misconfigured server can return an unrelated page.
• Category must actually match. Loose substring matches are rejected: a batch retort is not a continuous tunnel steriliser, and a mud conveyor is not a self-drilling screw. Very short product names are matched only against comparably short labels, because loose matching produces false links at directory scale.
• Names recorded as published. Where a registered legal name differs from the export brand, both are recorded.

Links that fail these checks are removed and the reason is recorded against the company profile. A manufacturer link means the company publishes that product on its own site. It is not an audit, a capability assessment, or confirmation that the company can meet a particular order.

• Check that the page has a clear purpose and contains useful information beyond a title or taxonomy label.
• Remove duplicate topic paths and use one canonical URL for each concept.
• Avoid publishing performance, tolerance, certification, capacity, or compliance claims without an attributable source.
• Label generated or assisted text as editorial reference material and require human review before it is treated as verified.

• CNFX does not conduct factory audits, laboratory tests, financial checks, sanctions screening, or legal due diligence unless a page explicitly says otherwise and identifies the evidence.
• Technical values are general research guidance, not engineering specifications for a particular order.
• Certificates, ownership, equipment, capacity, and contact details can change after publication.
• Users remain responsible for supplier qualification, samples, contracts, inspection, payment controls, and regulatory compliance.

If you find an incorrect, outdated, duplicated, or unsupported statement, email [email protected] or use the contact page. Include the page URL, the disputed field, the correct information, and a primary source where possible.

• Clear factual errors are corrected as soon as practical.
• Material corrections should update the review date and, where useful, add a correction note.
• Unsupported manufacturer claims may be removed or marked unverified while evidence is reviewed.

CNFX does not sell rankings. Paid services, if introduced, must not determine editorial conclusions or search visibility without a clear sponsored label. Manufacturer inclusion is not an endorsement, and omission is not a negative assessment.
