Source Policy
We prefer primary research, authoritative public agencies, current official labels, official manufacturer records and verified certification databases. Merchant pages are used carefully for price and availability snapshots.
Our commitments
- Every material fact should have provenance.
- Retrieval and review dates are preserved.
- Unsupported manufacturer statements are labeled as claims, not facts.
Effective date: September 1, 2026. Review cycle: at least annually or after a material policy change.
