For industries that have difficulties in paying work-related injury insurance premiums according to the total wages, the specific payment methods of work-related injury insurance premiums shall be stipulated by the administrative department of social insurance of the State Council.
Article 11
Work-related injury insurance funds are gradually implemented at the provincial level.
Cross-regional industries with large production mobility can participate in industrial injury insurance in different places in a relatively centralized way. The specific measures shall be formulated by the administrative department of social insurance of the State Council in conjunction with the relevant departments in charge of industry.
