Converting other non-GHS classifications to CLP

It is theoretically possible to convert other non-GHS classifications (that is classifications other than CHIP or Transport).

However, to do this, you would need to know what the classification hazards and thresholds are in the other classification system.

If you are not an expert in the original hazard classification system, it may be simpler to use data from a non-GHS Safety Data Sheet to classify the hazards from first principles, see  https://ttenvironmenta.wpengine.com/clp-knowledgebase/using-data-from-non-clp-safety-data-sheets/ and https://ttenvironmenta.wpengine.com/knowledgebase_category/first-principles-clp-classification/ .
