I have checked with Indus Motor Company and they did not reply and there is no certificate available on their website. Principally we are customers and after using the product most of us agree the quality of new Corolla is not up to the mark comparing with imported Japanese models. If you have any evidence that they have the required certifications, please prove it.
I believe the IMC quality control is ineffective if they have any. As far as the safety is concerned, it is out of question. This is quite obvious... maximize profit at the cost of poor quality parts and no safety and there is no check for that!
