We do have some products in for which we do not have any sort of identifier (neither CAS or UN) and that substance is printed on MSDS as CAS# not available, but under component we mention its name and under percentage we will provide XY%.
My concern is, how expert rule can work on this scenarios ? do I need to write my own rule ? we do have these types of substance around 10-15. How Expert rule calculate the Standard composition by ECBP ?
