CLP hazard classes

Delegated Regulation (EU) 2023/707 added endocrine, PBT/vPvB, and PMT/vPvM hazard classes to CLP

Direct answer. CLP, Regulation (EC) No 1272/2008, classifies substances and mixtures into hazard classes. Commission Delegated Regulation (EU) 2023/707 amended Annex I to add new hazard classes for endocrine disruption for human health and for the environment, and for PBT/vPvB and PMT/vPvM substances and mixtures. The quotes below are from the original English Official Journal of that delegated regulation, OJ L 93, 31 March 2023, CELEX 32023R0707, read as the Publications Office HTML of that issue. The ELI page is the public citation. This page is limited to those 2023 additions. It is not legal advice.

Checklist

• Read Section 3.11 for endocrine disruption for human health, and Section 4.2 for the environment.
• Read Section 4.3 for PBT and vPvB, and Section 4.4 for PMT and vPvM. The headings are quoted below.
• Use the EUH statement the table prints. This page does not invent a pictogram for these classes.
• Read the application-in-time sentences before you treat a date as already binding for every product already on the market.

What the act adds

Article 1: “Regulation (EC) No 1272/2008 is amended as follows.” Point (1): “Annex I is amended as set out in Annex I to this Regulation.”

Annex I then says: “in Part 3, the following Section 3.11 is added:” and the inserted heading is “3.11. Endocrine disruption for human health.” Later: “in Part 4, the following Sections 4.2, 4.3 and 4.4 are added,” headed “4.2. Endocrine disruption for the environment,” “4.3. Persistent, Bioaccumulative and Toxic or Very Persistent, Very Bioaccumulative properties,” and “4.4. Persistent, Mobile and Toxic or Very Persistent, Very Mobile properties.”

The Commission’s Environment news item of 20 April 2023 says: “The Delegated Regulation introduces new hazard classes for endocrine disruptors, as well as for chemicals that do not break down in the environment and can accumulate in living organisms, or risk entering and spreading across the water cycle, including drinking water.”

Definitions in Section 3.11

Section 3.11.1.1, as written:

• “endocrine disruptor” means a substance or a mixture that alters one or more functions of the endocrine system and consequently causes adverse effects in an intact organism, its progeny, populations or subpopulations;
• “endocrine disruption” means the alteration of one or more functions of the endocrine system caused by an endocrine disruptor;
• “adverse effect” means a change in morphology, physiology, growth, development, reproduction or lifespan of an organism, system, population or subpopulation that results in an impairment of functional capacity, an impairment of the capacity to compensate for additional stress or an increase in susceptibility to other influences;

Section 4.2.1.1 repeats those three definitions for endocrine disruption for the environment. The environment definition of “endocrine disruptor” uses the same words as the human-health definition quoted above.

Category 1 and category 2

Recital (10): “The level of evidence as regards endocrine disrupting properties may be of different scientific strength. It is therefore appropriate to create two categories of endocrine disruptors: known or presumed endocrine disruptors (category 1) and suspected endocrine disruptors (category 2), both for human health and for the environment.”

Table 3.11.1 is headed “Hazard categories for endocrine disruptors for human health.” Its category headings are “CATEGORY 1 / Known or presumed endocrine disruptors for human health” and “CATEGORY 2 / Suspected endocrine disruptors for human health.”

Table 4.2.1 is headed “Hazard categories for endocrine disruptors for the environment.” Its category headings are “CATEGORY 1 / Known or presumed endocrine disruptors for the environment” and “CATEGORY 2 / Suspected endocrine disruptors for the environment.”

Hazard statements

Table 3.11.3, “Label elements of endocrine disruption for human health,” prints these hazard-statement cells:

Table 3.11.3 includes a Symbol/pictogram row. In the Official Journal HTML, that row does not print a pictogram name or an image. This page does not invent one. Pictograms already assigned GHS01 to GHS09 are CLP hazard pictograms. The signal-word cells in Table 3.11.3 are Danger for Category 1 and Warning for Category 2. Signal words generally are CLP signal words.

Section 4.3 defines “PBT” as “a persistent, bioaccumulative and toxic substance or mixture that meets the classification criteria set out in Section 4.3.2.1” and “vPvB” as “a very persistent and very bioaccumulative substance or mixture that meets the classification criteria set out in Section 4.3.2.2.” Section 4.4 defines “PMT” and “vPvM” in the same pattern, pointing at Sections 4.4.2.1 and 4.4.2.2. Their label tables print EUH440, EUH441, EUH450, and EUH451. The EUH list that already covers other supplemental statements is CLP EUH statements.

Dates, quoted from the application-in-time paragraphs

Section 3.11.2.4, substances: “From 1 May 2025 at the latest, substances shall be classified in accordance with the criteria laid down in Sections 3.11.2.1 to 3.11.2.3.” “However, substances which were placed on the market before 1 May 2025 are not required to be classified in accordance with the criteria laid down in Sections 3.11.2.1 to 3.11.2.3 until 1 November 2026.”

Section 3.11.3.4, mixtures: “From 1 May 2026 at the latest, mixtures shall be classified in accordance with the criteria laid down in Sections 3.11.3.1, 3.11.3.2 and 3.11.3.3.” “However, mixtures which were placed on the market before 1 May 2026 are not required to be classified in accordance with the criteria laid down in Sections 3.11.3.1, 3.11.3.2 and 3.11.3.3 until 1 May 2028.”

Sections 3.11.4.2 and 3.11.4.3 repeat those dates for labelling. Sections 4.2, 4.3, and 4.4 each have their own application-in-time paragraphs with the same two pairs of dates, pointed at their own section numbers. This page quotes the Section 3.11 pair in full and does not retype every parallel sentence.

Classes that pre-date 2023

This guide is limited to the classes 2023/707 added. It does not restate the physical, health, and environmental classes that were already in Annex I. Those surfaces are the guides below, including CLP vs GHS and hazard statements.
