As IMDS is a material reporting system,the purpose of creating a material is to inform the customer what substances are present in the material.
Note that an MSDS (Material Safety Data Sheet) is not usually suitable to create an MDS because an MDS requires entry of 100% of the substances in the final material, and an MSDS rarely provides this information.
The material classification is mandatory for material type datasheets. The information is stored in this area.
