Homologation requirements act as barriers to international markets for automotive companies. While India has developed automotive technology, homologation standards make it difficult to access international markets. Homologation involves obtaining governmental approval by documenting vehicle performance, submitting samples for testing, and demonstrating compliance. It can involve type approval, where compliance is proven before sale, or self-certification, where witnessed testing before sale is not required. Meeting homologation requirements increases costs, but provides access to growing automotive markets.
