On 27 November 2024, the EU General Court dismissed a legal challenge by BASF SE, Dow Europe GmbH, and Nouryon Functional Chemicals BV against the European Commission's classification of DTPA substances as reproductive toxicants in Category 1B under Regulation (EU) 2022/692. The judgment reinforces the Commission's stance on stringent chemical labelling standards to protect human health.
Background Of The Case
The applicants, manufacturers and importers of DTPA (N-carboxymethyliminobis(ethylenenitrilo)tetra(acetic acid)) and its sodium and potassium salts, sought annulment of the regulation classifying DTPA as a presumed human reproductive toxicant. DTPA, widely used in detergents, textiles, and industrial processes, was labelled with the hazard statement "H360D" (may damage the unborn child).
Key Legal Arguments
The applicants argued that the classification was flawed due to:
A lack of intrinsic properties causing reproductive toxicity.Insufficient evidence linking DTPA to specific reproductive harm.The absence of an impact assessment by the Commission.
They also highlighted procedural inadequacies, including a lack of public consultations and failure to address interspecies differences in reproductive effects.
Court's Findings
The General Court validated the classification, emphasising the following:
Scientific Basis: The European Chemicals Agency’s Risk Assessment Committee (RAC) demonstrated a plausible mode of action linking DTPA to reproductive toxicity through induced zinc deficiency, which impacts foetal development.Maternal Toxicity: The Court rejected claims that observed foetal effects were secondary to maternal toxicity, stating the evidence indicated direct developmental harm.Procedural Compliance: The Court found no legal requirement for an additional impact assessment under EU regulations. It affirmed that public consultations adequately addressed the classification proposals.

curia.europa.euQuestions about this change
What does the classification of DTPA as a Category 1B reproductive toxicant mean for manufacturers and consumers?
The classification of DTPA and its salts as Category 1B under EU chemical regulations means these substances are considered presumed human reproductive toxicants based on animal studies. For manufacturers, this imposes strict labelling and packaging requirements, including the hazard statement "H360D" (may damage the unborn child). Consumers are informed of the potential health risks when using products containing DTPA, ensuring safer usage and adherence to health guidelines. The ruling aligns with the EU’s goal of protecting human health from hazardous substances.
How was the classification of DTPA as a reproductive toxicant scientifically justified?
The classification was based on detailed evaluations by the RAC, which identified that DTPA caused developmental toxicity in animal studies. The mechanism involved DTPA binding to zinc, creating a deficiency that impaired foetal development. This effect was shown to occur independently of maternal toxicity, which strengthened the classification's justification. The RAC also considered additional studies and public consultations before recommending the Category 1B classification, concluding that the effects observed in animals were relevant to human health.
