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• Unverified: Evidence was unavailable, incomplete, outdated, or not independently checked.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. Optional model-data preparation is a paid service. Payment does not buy directory ranking, a verification label or a favourable editorial conclusion. Manufacturer inclusion is not an endorsement, and omission is not a negative assessment.
