We understand that although most chemical regulations have similar endpoint and data requirements, there are specific and nuanced differences. This is especially true in the Asia Pacific region. For example, not all jurisdictions accept QSARs in place of in-vitro data. Some jurisdictions, like China, insist on having environmental studies conducted locally on local organisms. It can, therefore, be challenging to work out how to replicate a chemical registration from one jurisdiction to another.
You also need to consider the chemical and regulatory approach. For example: is it pre-supply? Is the focus based on hazard or risk assessment? Or what is the scope of substances included in the regulations (e.g., polymers versus monomers)?
