According to the investigation team of the State Council, the "812" dangerous goods warehouse fire and explosion accident in Tianjin Port was a particularly serious production safety liability accident.

The investigation team found that the direct cause of the accident was that the nitrocellulose in the container on the south side of the arrival area of the dangerous goods warehouse of Hairui Company was partially dried due to the loss of wetting agent, which accelerated the decomposition and heat release under the action of high temperature (weather) and other factors. Causing dangerous chemicals such as nitrocellulose in adjacent containers to burn in a large area for a long time, leading to the explosion of dangerous chemicals such as ammonium nitrate accumulated in the arrival area.

The investigation team found that Hairui Company seriously violated relevant laws and regulations and was the main responsible unit for the accident. The company ignored the main responsibility of safety production, seriously violated the overall urban planning of Tianjin and the regulatory detailed planning of Binhai New Area, illegally built a dangerous goods yard, illegally operated and illegally stored dangerous goods, and the safety management was extremely chaotic, with long-standing safety hazards.

At the same time, the investigation team found that the relevant local party committees, governments and departments have problems such as non-compliance with laws, lax enforcement, poor supervision and inadequate performance of their duties. Tianjin transportation, port, customs, safety supervision, land planning, market and quality inspection, maritime affairs, public security, environmental protection and administrative examination and approval of Binhai New Area failed to seriously implement relevant laws and regulations, did not seriously perform their duties, and illegally conducted administrative licensing and project review, resulting in a serious lack of daily supervision; Some responsible persons and staff members take bribes and pervert the law and abuse their powers. Tianjin Municipal Party Committee, Municipal Government, Binhai New Area Party Committee and District Government failed to fully implement relevant laws and regulations, and neglected to supervise the behaviors of relevant departments and units in violation of urban planning and the problems existing in safety production management. As the competent department of port dangerous goods supervision, the Ministry of Transport failed to supervise and inspect the safety management of port dangerous goods in accordance with its statutory duties, and the guidance to Tianjin's transportation system was not in place. The General Administration of Customs urged and guided Tianjin Customs to do a good job.
