Transparency Project Certification
Clean Label Project
Certifies products for purity, testing for contaminants and ingredient transparency.
The Transparency Project Certification costs $300 USD, takes approximately 12 weeks, and requires around 40 hours of study.
Key Strengths
- Independent third-party laboratory testing for contaminants including heavy metals, pesticides, and plasticizers
- Credible nonprofit governance with no commercial conflicts of interest
- Consumer-facing public seal that builds trust at point of purchase
- Covers a wide range of product categories including food, supplements, and pet products
- Signals genuine ingredient transparency beyond standard regulatory compliance
- Recognized by health-conscious consumers and clean-label advocacy communities
Ideal For
This certification is best suited for consumer product brands — particularly in food, supplements, pet food, and personal care — that want to demonstrate ingredient transparency and purity to health-conscious buyers. It is especially valuable for emerging or challenger brands seeking third-party validation to compete against established players, and for companies whose target customers actively scrutinize labels and contaminant risks.
