Privacy & Data Policy

This sub-site publishes manufacturer and supplier qualification intelligence. This page explains how profiles are sourced, verified and labelled.

Last updated: 2026-10-07

1. What this sub-site publishes

Supplier profiles: company identity, product range, declared operations and — where available — certifications and capacity. No profile is published without a real source and a verification status. Fields that are unknown are left empty, never invented.

2. Verification statuses

Verified — backed by reliable sources or documented on-site/file verification.
Supplier Reported — figures provided by the supplier's own public statements; not independently confirmed by us.
Third-Party Verified — supported by independent testing or certification.
Unverified — basic identity only.

A supplier-reported value is a claim, not a fact. Verify before you contract. See the verification model page for the full methodology.

3. What we do not collect

No analytics, no tracking cookies, no advertising pixels. The hosting platform may keep standard security logs under its own policy.

4. Inquiries

This sub-site has no forms. Network-wide terms: main site privacy policy and terms of use. Contact: sales@guotan.com.
