The Environmental Defense Fund posted a blog item on August 27, 2026, titled “American Chemical Safety Decisions Should Be Based on American Conditions of Use.”
The blog item argues that country-specific exposure levels, use patterns, and regulatory requirements matter more than whether a chemical has been approved elsewhere.
EDF contends that the Environmental Protection Agency must consider how a chemical will be produced and used in the United States before granting approval.
Relying on another country’s regulatory decision, EDF argues, is an inadequate substitute for a proper domestic risk assessment tailored to American conditions.
The House and Senate have each held hearings on discussion drafts of legislation that would amend the Toxic Substances Control Act, known as TSCA, as reported in January and March 2026.
EDF’s position is informed in part by findings from an OECD New Chemicals Task Force examining the feasibility of cross-border regulatory recognition.
The task force “identified fundamental challenges to one country automatically adopting another country’s risk-based new chemical decision,” according to EDF’s blog item.
OECD participants ultimately concluded that new chemical risk-based decisions are too dependent on country-specific conditions to be automatically adopted by another jurisdiction.
As a result, the OECD walked away from the concept of mutual acceptance of new chemical risk-based regulatory decisions entirely.
The idea may appear efficient on the surface, but international participants found the practical barriers to harmonisation too significant to overcome.
EDF’s blog item enters the debate at a politically sensitive moment, with Congress actively considering changes to the framework governing how new chemicals are reviewed and approved domestically.
The outcome of those legislative discussions could shape how closely the EPA is permitted or required to consider foreign approvals when assessing new chemical applications in the United States.
