Abstract: A product substance inspection system includes an expansion module, an inspection module, and a preference-setting module. The expansion module expends regulatory information into a plurality of substance thresholds. The inspection module obtains material composition corresponding to a constituent from the aggregate material composition stored in a database, and compares each element in the material composition with the corresponding substance threshold. When the inspection module determines that the value of a specific element in the material composition exceeds the corresponding substance threshold, the preference-setting module replaces the constituent to which the specific element belongs according to the preference settings.
