Meaning
A distinct statutory category of non-public information under Chinese data security law requires heightened administrative protection due to its potential impact on national security and public interests. The concept of important data is defined not by personal privacy, but by the relevance of the data to the economic development and critical infrastructure of the nation. It excludes ordinary corporate files but covers large-scale industrial and demographic datasets.
It forms the middle tier of China’s three-tiered data classification system, sitting below core data and above ordinary data.
Classification Metric
Sector-specific guidelines published by various ministries and regional authorities identify the quantitative and qualitative thresholds that elevate data to this status. Industry regulators in automotive, finance, telecommunications and energy publish lists of parameters that determine which datasets belong to this category. The classifications are dynamic, changing in response to technological developments and national security requirements.
Security Obligation
Entities handling these classified datasets must appoint a dedicated data security officer and establish a internal management department to oversee protection practices. Regular risk assessments must be conducted, and the resulting reports must be submitted to the competent regulatory authorities annually. Any security breach must be reported immediately to prevent broader systemic risks.
Export Restriction
Cross-border transmission of this information is strictly prohibited unless the handler passes a mandatory security assessment conducted by the Cyberspace Administration of China. This regulatory check prevents the unauthorized outflow of strategic industrial and economic statistics to foreign entities. Violations can lead to severe penalties, including the revocation of business licenses and criminal prosecution of the responsible executives.
