In a statement quoted by Reuters, the authorities in Jiang'an county said the blast happened at a chemical plant run by Yibin Hengda Technology.
Photos on Chinese social media showed a huge fire and plumes of smoke rising from the facility.
It is not clear what caused the explosion.
According to Xinhua the fire, which broke out on Thursday evening, had been put out early Friday. Those injured in the blast were in a stable condition.
Authorities have begun an investigation, the news agency said.
The company, which makes chemicals for the food and pharmaceutical industries, did not immediately answer telephone calls from Reuters to seek information.
According to local media reports, the three-storey buildings of the factory burnt down to their steel frames and nearby buildings had their windows shattered.
It comes amid a drive to strengthen industrial safety, with China ramping up checks over the last year, in the wake of some high-profile incidents at coal mines and chemical plants.
The accident follows previous high-profile disasters at chemical plants in China.
In 2015, 173 people died in an explosion at a chemical warehouse in the north-eastern port city of Tianjin.
An official investigation into the blast found that corruption, political connections and official collusion allowed corners to be cut and safety systems to be overridden.
