India's Trade and Economic Partnership Agreement (TEPA) with the European Free Trade Association (EFTA) — comprising Switzerland, Norway, Iceland and Liechtenstein — entered into force on October 1, 2025. The agreement combines deep tariff concessions with a binding $100 billion investment commitment over 15 years. It is India's first FTA with developed European economies and is expected to boost pharmaceutical, chemical, and financial services sectors. By October 5, initial implementation was underway, including customs duty reductions.
