Chemical safety depends on access to reliable information, yet not every detail submitted to regulators becomes publicly available. A recent C&EN analysis published on July 1, 2026 examined EPA data and found that companies more frequently claim Confidential Business Information, or CBI, status under the Toxic Substances Control Act for chemicals with higher hazard classifications. While CBI protections serve an important legal purpose, the findings raise practical questions for procurement teams responsible for evaluating supplier risk and maintaining safe supply chains.
For chemical buyers, the presence of a CBI claim should not automatically trigger concern or confidence. Instead, it should encourage a more thorough review of the information available and the additional evidence needed before procurement decisions are made.
The Toxic Substances Control Act allows companies to request Confidential Business Information protection for specific information submitted to the EPA. These protections exist to prevent disclosure of legitimate trade secrets or commercial and financial information that could harm a company's competitive position if released publicly.
A CBI claim is not permanent simply because a company requests it. Under Section 14 of TSCA, companies must substantiate their claims, demonstrating why the information qualifies for confidential treatment under the law.
The EPA also has authority to review those submissions and challenge claims that fail to meet the required legal standard. This review process helps balance commercial confidentiality with the public's interest in chemical safety information.
The C&EN feature highlights an important pattern rather than a simple cause-and-effect relationship. According to its analysis of EPA data, companies appear more likely to request CBI protection for chemicals with higher hazard classifications.
That observation does not mean every confidential submission involves a highly hazardous substance. Likewise, it does not mean every hazardous chemical receives confidential treatment. The finding instead suggests that procurement professionals should pay closer attention whenever confidentiality limits the information available for a safety review.
Understanding this distinction prevents buyers from making assumptions while encouraging more comprehensive due diligence.
A CBI claim protects certain information from public disclosure, but it does not automatically describe the safety profile of a chemical.
Buyers should remember several key points:
A confidentiality claim protects commercial information, not the hazard itself.
Companies must justify why the information deserves confidential treatment.
EPA retains authority to review and reject unsupported claims.
Publicly available information may still include hazard classifications, regulatory decisions or risk management requirements.
The existence of a CBI claim should therefore be treated as one factor within a broader supplier evaluation process rather than a standalone indicator of product safety.
Procurement professionals often evaluate suppliers using multiple sources of technical and regulatory information. When confidentiality limits publicly available data, additional verification becomes increasingly important.
Effective risk assessments may include:
Requesting updated Safety Data Sheets from suppliers.
Asking suppliers to explain how they manage regulatory compliance.
Reviewing available hazard classifications and exposure guidance.
Evaluating whether substitute materials are commercially available.
Confirming that suppliers maintain appropriate product stewardship programs.
These steps provide greater confidence even when certain information remains confidential under regulatory provisions.
Strong supplier relationships become even more valuable when confidential information limits public transparency. Rather than relying solely on regulatory databases, buyers should engage suppliers directly to understand product stewardship practices and safety management systems.
Questions about testing procedures, quality control, regulatory compliance and handling recommendations often provide meaningful insight without requiring disclosure of protected commercial information. Suppliers that communicate openly about these areas can help build greater confidence throughout the purchasing process.
Procurement teams should also maintain regular reviews of supplier documentation to ensure information remains current as regulations evolve.
Commercial confidentiality and public safety do not necessarily conflict. Many legitimate innovations depend on protecting proprietary manufacturing processes, formulations and commercial information. At the same time, buyers require sufficient safety information to make informed procurement decisions and meet their own regulatory responsibilities.
The TSCA framework attempts to balance these objectives by requiring companies to substantiate confidentiality claims while giving the EPA authority to challenge claims that do not satisfy legal requirements. This process supports both innovation and regulatory oversight.
For procurement professionals, the practical takeaway is clear. A CBI claim should prompt additional due diligence rather than immediate assumptions about either safety or risk. Combining regulatory information with supplier engagement, technical documentation and independent risk assessment creates a stronger foundation for purchasing decisions and long-term supply chain resilience.
