GHS Substance Classifications for SDS Authoring & Labels Paul Lloyd
Need for Substance Classifications Required if individual substances are sold Essential requirement for classifying mixtures in absence of test data for mixture 3E Generate automated output is dependent on substance classifications Display of component substance classifications is mandatory for EU SDS s for mixtures
Classification Sources Poll How do you get substance classifications? Obtain test data for all classes and select the most appropriate Use the classifications automatically generated by 3E Generate Use classifications from vendor SDS s Use classifications from regulatory lists
Approaches to Classification Theoretical requirement Based on comparing physical, chemical and toxicological data against specified criteria Availability of data In-house expertise, particularly with regard to GHS criteria Interpretation of data Very time consuming
Approaches to Classification Automated classification utilizing information from databases By default, must be conservative and take most severe toxicological values and /or authority classification Data does not provide the whole story, generally numeric with no qualification. Limit tests are particularly problematic Data may be misreported, particularly when taken from secondary sources. LD50 of 5.1 g/kg is very different to 5.1 mg/kg
1-methoxy 2- propanol CAS 107-98-2
GHS Classification LD50 >1840 mg/kg means LD50 could be 1840.1 mg/kg Applying the relevant criteria 1840.1 mg/kg is <2000 mg/kg therefore Category 4
1-methoxy 2- propanol CAS 107-98-2
GHS Classification Hence LD50 >1840 mg/kg should not be used as basis for classification All other LD50 data is >5000 mg/kg Therefore, most appropriate conclusion is Not classified
Approaches to Classification Classifications from Vendor SDS s Reliability Conflicting information from different suppliers Coverage of all GHS classes and categories, particularly if taken from non domestic format SDS s or if your product is to be exported May be best option for substances with variable composition (ethoxylated fatty alcohols, petroleum products etc.)
Approaches to Classification Utilizing existing classifications from Regulatory Lists Which list? Reliability Substances without existing classifications Acceptability Regulators and Marketplace
Global Supply Poll Do you supply outside of the EEA? What classification do you use? EU Regulation (EC) 1272/2008 [CLP] classification only Global GHS classification Country specific classifications
Methyl propyl ketone (CAS 107-87-9) Acute toxicity (inhalation) classification EU CLP Annex VI Not listed China SAWS Category 3 (toxic if inhaled) Japan NITE Category 3? REACH Registration database Not Classified
Changes to Lists Japan NITE 2006 Japan NITE 2015
Questionable Data
REACH Registration Dossier
GHS Classification Hence LC50 >25.5 mg/l can be considered reliable Therefore, most appropriate conclusion is: Not classified However, before quoting that value consider: Is it copyright and are you entitled to print it?

Pros and Cons of Lists EU CLP Annex VI Widely recognized Hazard classes other than those with classification need to be assessed Basis of many is unknown / hard to trace Does not cover all GHS categories China SAWS Covers majority of GHS categories Basis of classifications not available
Pros and Cons of Lists Korea MOE Does not cover all GHS categories Basis of classification hard to find Taiwan CLA Covers majority of GHS categories Basis of classification hard to find Classifications tend to be conservative
Pros and Cons of Lists Japan NITE Basis of classification available Often very conservative classifications Occasional misinterpretations of GHS criteria Korea KOSHA Dubious quality / little expert judgment Access to original data / basis for classification problematic
Pros and Cons of Lists EU REACH Dossiers Supporting data available Large number of substances Not all GHS categories covered Not an official classification, multiple classifications for same CAS number in some cases Quality is variable dependent on Registrant Supporting data may be copyright protected

Summary of Pitfalls Missing classifications (Building blocks) - Example: Flammable liquid 4 Inappropriate classifications failing to reflect specific authority interpretations - Examples: carcinogenicity of Quartz, Ethyl benzene Classification algorithms are sensitive to seemingly minor inaccuracies - Example: Impact of not classified verses classification not possible in acute toxicity calculations
Summary of Pitfalls Unnecessary over-classification impacting labeling, shipping and customer perception Can you support the classification if challenged by customers or regulators?
