On December 16 and 24, 2025, the Ministry of Industry and Information Technology (MIIT) of China opened two public consultations on the project proposals to revise 8 critical GHS standards, targeting:
GB 30000.7-2013 Rules for classification and labelling of chemicals - Part 7: Flammable liquids
GB 30000.15-2013 Rules for classification and labelling of chemicals - Part 15: Oxidizing solids
GB 30000.19-2013 Rules for classification and labelling of chemicals - Part 19: Skin corrosion/irritation
GB 30000.20-2013 Rules for classification and labelling of chemicals - Part 20: Serious eye damage/eye irritation
GB 30000.21-2013 Rules for classification and labelling of chemicals - Part 21: Respiratory or skin sensitization
GB 30000.22-2013 Rules for classification and labelling of chemicals - Part 22: Germ cell mutagenicity
GB 30000.27-2013 Rules for classification and labelling of chemicals - Part 27: Aspiration hazard
GB 30000.29-2013 Rules for classification and labelling of chemicals - Part 29: Hazardous to the ozone layer
The project cycle for these revisions is set for 16 months. Their technical content will maintain consistency with UN GHS Rev. 11.
Background
As China is a major producer and trader of chemicals, the implementation of updated GHS standards helps break down technical barriers to trade and facilitates international exchange. Establishing safety specifications that are aligned with current international standards is deemed essential for supporting chemical import and export activities while safeguarding public safety. GB 30000 series (Parts 1~30) are mandatory national standards critical to China's GHS implementation. The revision of these standards is a necessary step to align China's GHS technical content with updated international norms.
On July 24, 2024, the GB 30000.1-2024 Rules for classification and labelling of chemicals - Part 1: General rules, which adopts the UN GHS Rev.8, was published and set to take effect on August 1, 2025. On June 30, 2025, the GB 30000.30-2025 Specification for classification and labelling of chemicals - Part 30: Desensitized explosives was published and will take effect on July 1, 2026, which stipulates that the classification criteria and labelling elements for desensitized explosives shall adhere to UN GHS Rev.10.
The other parts (Parts 2 ~ 29), which were issued in 2013 based on the UN GHS Rev. 4, shall be updated accordingly to ensure consistency across the GHS regulatory system. Notably, the project proposals this time target 8 parts, indicating that the revisions will reference the UN GHS Rev.11 to ensure forward-looking alignment.
Scope and Technical Content
The revisions will define the terms, definitions, classification criteria, decision logic, and labelling requirements for certain hazard classes, respectively. A significant administrative change for all these standards is the shift from "partial mandatory (classification and labelling)" to "full mandatory" status. Key technical updates include:
GB 30000.7 (Flammable Liquids): The revision will align with Chapter 2.6 of the UN GHS Rev. 11. It will supplement the classification criteria by including results from open-cup flash point tests for determination and will improve test methods.
GB 30000.15 (Oxidizing Solids): This revision will align with the Oxidizing Solids chapter of the UN GHS Rev. 11. It will introduce the O.3 standard and add a new reference substance, Calcium Peroxide, to the testing protocols.
GB 30000.19 (Skin corrosion/irritation): This revision will align with the Skin corrosion/irritation chapter of the UN GHS Rev. 11. It will incorporate in vitro/ex vivo data to classify skin corrosion/irritation. The appendices will also be updated to maintain technical consistency with the UN GHS Rev. 11 and other parts of the GB 30000 series.
GB 30000.20 (Serious eye damage/eye irritation): This revision will align with the Serious eye damage/eye irritation chapter of the UN GHS Rev. 11. It will incorporate in vitro/ex vivo data to classify this hazard.
GB 30000.21 (Respiratory or skin sensitization): This revision will align with the Respiratory or skin sensitization chapter of the UN GHS Rev. 11. It will focus on integrating non-animal testing methods and in vitro methods to classify this hazard.
GB 30000.22 (Germ cell mutagenicity): This revision will align with the Germ cell mutagenicity chapter of the UN GHS Rev. 11. It will add more examples of germ cell mutagenicity/genotoxicity testing, somatic cell genotoxicity testing, and in vitro mutagenicity testing.
GB 30000.27 (Aspiration hazard): This revision will align with the Aspiration hazard chapter of the UN GHS Rev. 11. It will clarify the concentration range of the "relevant components" in the mixture.
GB 30000.29 (Hazardous to the ozone layer): This revision will align with the Hazardous to the ozone layer chapter of the UN GHS Rev. 11. It will add controlled substances to the Montreal Protocol Control List in Appendix A.
The appendices of these standards will also be updated to maintain technical consistency with the UN GHS Rev. 11 and other parts of the GB 30000 series.
Comment Period
The public consultation period for these project proposals concludeed on December 23, 2025 and December 30, 2025. Industry stakeholders wishing to provide feedback on the proposed revisions should submit their comments via email ([email protected]) before the deadlines.
