Event Details
This session aims to provide stakeholders with:
-
An update on the current status of the CLH proposals.
-
Insights into the potential implications for the industry.
-
Guidance on how to engage in the public consultation process.
Potential classifications under the current ECHA ARN, with a specific focus on the use of rosin in different applications, will have considerable direct and indirect effects on vital products used in critical applications, the global economy, and various industry sectors.
The PCA, H4R, and HARRPA disagree strongly with these proposed classifications since, based on the available toxicological data, none of these substances raises any concern for reprotox hazard and therefore do not meet the criteria for classification. We are jointly examining all scientific data to support our position that a reproductive toxicity classification for any of the below substances is scientifically not justified and therefore, PCA, along with HARPPA and H4R, will contest such a classification proposal. We are also assessing the implications of product classification and regulatory compliance, as well as the effect this will have on multiple industries and their stakeholders.
Please follow this link to register for the upcoming webinar, and the details will be emailed to you directly. We recommend you include any colleague involved with the procurement or sale of raw materials, regulatory staff, and the scientific team/toxicologists.
Please treat this message as privileged and only forward it to stakeholders affected by the classification and/or who would benefit from the content and participation.
Monday the 1st of September 2025, ECHA published the CLH reports for the substances listed below in Table 1. Consequently, the Public Consultation is now open and spans 60 days, during which stakeholders are invited to provide comments on the hazard classes proposed in the CLH report. The CLH reports submitted by the Norwegian Environment Agency will undergo an evaluation by the Risk Assessment Committee of the ECHA over the next 12 months.
The CLH reports can be found here.

The H4R Consortium and PCA are reviewing the CLH reports for Harmonised Classification and Labelling and intend to submit documents during the public consultation. The submitted documents will include:
- all relevant scientific information on the toxicity to reproduction (or lack thereof) of Rosins and derivatives,
- the outcome of the two new investigative studies sponsored by H4R and PCA, which provide evidence to support our position that none of these substances raise concern for reprotoxicity hazard and therefore do not meet the criteria for classification.
- the outcome of the two new investigative studies sponsored by H4R and PCA, which provide evidence to support our position that none of these substances raise concern for reprotoxicity hazard and therefore do not meet the criteria for classification.
During public consultation, all stakeholders are invited to provide relevant information, including:
- Toxicological data, such as information on the intrinsic toxicological properties of rosin and rosin derivatives and/or mechanistic studies.
- information about the use of the substance, including its essentiality and critical technical function in your applications, exposure conditions and risk management measures currently in place.
- information about the use of the substance, including its essentiality and critical technical function in your applications, exposure conditions and risk management measures currently in place.
Should you possess such data, we advise to contact the H4R consortium secretariat. The secretariat is equipped to provide comprehensive support throughout the submission process, ensuring that your valuable information is integrated into the consortium's assessments.
Further information is being generated and an updated communication will follow once the CLH reports have been reviewed.
An online Webinar will be organized on the 14th October, 15:00 CET to provide your organization with status, next steps and guidance on the public consultation phase. More information will follow once it becomes available. In case you have any questions or would like to share any information with us, please contact us at manager@h4rconsortium.com.
