MUMBAI, India — India announced late Saturday that it would raise tariffs on 28 categories of imports from the United States, the latest escalation in what has been a slow-motion trade fight between the two countries.

The increased tariffs, on $1.4 billion of goods, went into effect Sunday morning in India and cover almonds, walnuts, apples and finished metal items, among other products.

Unlike other trade battles that President Trump has waged, such as the increasingly bitter feud with China, the conflict with India threatens far less economic pain to either country.
