The massive explosions last week in a toxic chemicals warehouse have killed at least 114 people, while injuring more than 700, according to Chinese officials.

Although the explosions occurred during holidays for Toyota, with no impact so far on production at its three lines near the affected area, the carmaker added: “Due to ongoing evacuation advisories, none of the three lines at Tianjin FAW Toyota Motor Co Ltd will be (in) operation from Aug 17 through 19.”

However, despite having a production plant in Tianjin, Toyota is among the least impacted automakers from the incident according to IHS Automotive. The automaker has reported some damage to its research-and-development facility in Tianjin, while two dealer shops have also sustained damage. In comparison, Hyundai, Renault, and Volkswagen (VW) have witnessed greater damage of thousands of vehicles parked at stockyards. Meanwhile, Mitsubishi said 600 of its vehicles could have been damaged as a result of the explosions.

IHS adds that some carmakers have started alternative route scheduling for vehicle shipments, while more are likely to do so going forward. Tianjin is one of the biggest automobile shipping ports in China and is widely used to ship vehicles within the country, especially northern parts. The port is also used for exports and imports and accounts for about 40% of China's imported cars, the largest share of any port in the country.

Toyota produced a total of 432,340 units at the twin plants in 2014, according to IHS Automotive estimates. While the current impact of the blasts is limited to the Corolla and Vios sedans, the Crown Royal and Reiz models are also likely to be affected going forward, according to Mark Fulthorpe, director, IHS Automotive light-vehicle production forecast.

"The estimated loss across the three lines would be 2,200 units per day," said Mr Fulthorpe.

“The blast might impact 30,000 to 60,000 imports of one million total car imports for this year," said Lin Huaibin, manager, IHS Automotive China light-vehicle sales forecast, adding that it is likely to take a couple of months before Tianjin port is back to normal operations.
