Champ d’application

This standard applies to the classification and labelling of chemical substances and mixtures that exhibit acute toxicity hazards. It is specifically designed for chemical manufacturers and importers aligning with the United Nations Globally Harmonized System (GHS) in China. Compliance with this standard is mandatory for hazard communication elements specified in Chapters 4 and 6.

Exigences techniques

GB 30000.18-2013 establishes the criteria for classifying chemicals into five acute toxicity categories based on the Acute Toxicity Estimate (ATE). The classification evaluates adverse effects occurring after oral, dermal, or inhalation exposure. Manufacturers must determine the appropriate hazard category for each exposure route to ensure accurate hazard communication. For mixtures, the standard provides a tiered approach to classification. It utilizes bridging principles—such as dilution, batch concentration, and substantially similar mixtures—to estimate toxicity without additional animal testing, referencing OECD Test Guidelines. When test data is unavailable, classification is determined using the additivity formula based on the known ATE values of the mixture's relevant components. Suppliers must calculate the overall mixture toxicity and apply the corresponding label elements for the most severe hazard category identified.

Méthodes d’essai

The standard references established toxicological testing to determine LD50 and LC50 values for substances. Key evaluation procedures include 4-hour inhalation studies for gases, vapors, and dusts/mists, with specific conversion factors applied for 1-hour test data. Animal testing should be avoided for Category 5 unless absolutely necessary for human health protection. Data derivation also relies on in vitro data, pH values, and expert judgment for corrosivity assessments.

Questions fréquentes

What products are regulated under GB 30000.18-2013?

It regulates chemical substances and mixtures that present acute toxicity hazards via oral, dermal, or inhalation routes. This applies to all chemical products entering the Chinese market requiring GHS classification.

Are there any updates from the previous version of GB 30000.18-2013?

Yes, it replaced GB 20592-2006. Key updates include modifying the scope to focus on "labels" rather than "warning labels," integrating precautionary statements into an informative annex, and adding label examples for acute toxicity.

How does GB 30000.18-2013 align with international standards?

The technical content is consistent with the UN GHS (Rev. 4). It utilizes the same 5-category system and ATE methodology, ensuring alignment with global hazard communication practices. International manufacturers can easily map their existing GHS classifications to this Chinese standard.
