“Important data” is a regulated data category under China’s data-security framework and can trigger obligations beyond ordinary personal-information compliance.
It is not simply any commercially important dataset. Identification depends on current national/sector rules, catalogues and the consequences that loss, alteration, destruction or misuse could have for national security, economic operation, public interests or other protected interests.

Short answers for orientation. The right result can change with the service model and current rules.
Is important data the same as sensitive personal information?
