New Hazards Classes Introduced for CLP Regulation

from European Union by

On March 31, 2023, the European Commission released the amendments to Annex I to Regulation (EC) No 1272/2008 as regards hazard classes and criteria for the classification, labelling and packaging of substances and mixtures (CLP), introducing several new classification criteria to identify endocrine disrupting chemicals (EDCs) and persistent and mobile substances.

The amended regulation also introduced four hazard classes for persistent and mobile substances. These are:

  • persistent, bioaccumulative and toxic (PBT);
  • very persistent, very bioaccumulative (vPvB);
  • persistent, mobile and toxic (PMT); and
  • very persistent, very mobile (vPvM).

Details are as follows:

Endocrine Disruption Chemicals

In accordance with the requirements of Part 3 under Annex I, endocrine disruptors for human health/ the environment can be allocated into one of two categories:

Hazard category

Hazard criteria for endocrine disruptors for human health

Hazard criteria for endocrine disruptors for the environment

Category 1

Known or presumed endocrine disruptors for human health.

The classification in Category 1 shall be largely based on evidence from at least one of the following:

  1. human data;
  2. animal data;
  3. non-animal data providing an equivalent predictive capacity as data in points a or b.

Such data shall provide evidence that the substance meets all the following criteria:

  1. endocrine activity;
  2. an adverse effect in an intact organism or its offspring or future generations; and
  3. a biologically plausible link between the endocrine activity and the adverse effect.

However, where there is information that raises serious doubt about the relevance of the adverse effects to humans, classification in Category 2 may be more appropriate.

Suspected endocrine disruptors for environment.

A substance shall be classified in Category 2 where all the following criteria are fulfilled:

(a) there is evidence of:

i. an endocrine activity; and

ii. an adverse effect in an intact organism or its offspring or future generations;

(b) the evidence referred to in point (a) is not sufficiently convincing to classify the substance in Category 1;

(c) there is evidence of a biologically plausible link between the endocrine activity and the adverse effect.

Category 2

Suspected endocrine disruptors for human health.

A substance shall be classified in Category 2 where all the following criteria are fulfilled:

(a) there is evidence of:

i. an endocrine activity; and

ii. an adverse effect in an intact organism or its offspring or future generations;

(b) the evidence referred to in point (a) is not sufficiently convincing to classify the substance in Category 1; and

(c) there is evidence of a biologically plausible link between the endocrine activity and the adverse effect.

Suspected endocrine disruptors for the environment.

A substance shall be classified in Category 2 where all the following criteria are met:

(a) there is evidence of:

i. an endocrine activity; and

ii. an adverse effect in an intact organism or its offspring or future generations;

(b) the evidence referred to in point (a) is not sufficiently convincing to classify the substance in Category 1; and

(c) there is evidence of a biologically plausible link between the endocrine activity and the adverse effect.

Generic concentration limits of components of a mixture classified as an endocrine disruptor for human health/the environment that trigger the classification of the mixture:

A mixture shall be classified as an endocrine disruptor for human health where at least one component has been classified as a Category 1 or Category 2 endocrine disruptor for human health and is present at or above the appropriate generic concentration limit as shown in the Table below for Category 1 and Category 2, respectively.

※ The concentration limits in this Table shall apply to solids and liquids (w/w units) as well as gases (v/v units). If a Category 2 endocrine disruptor for human health is present in the mixture as an ingredient at a concentration ≥ 0.1 % a SDS shall be available for the mixture upon request.

A mixture shall be classified as an endocrine disruptor for the environment where at least one component has been classified as a Category 1 or Category 2 endocrine disruptor for the environment and is present at or above the appropriate generic concentration limit as shown in Table below for Category 1 and Category 2, respectively.

CIRS Comments

There is no doubt that related enterprises may face various challenges as new hazard classifications have been introduced. Manufacturers of related substances should re-evaluate the hazards of substances within the transitional period. The legislative framework of several legislations, including chemicals, biocides, pesticides, toys as well as medical devices may have been affected.
