India has once again postponed the implementation of tariff on U.S. imports, saying they would now come into effect on Sept. 18.

The additional duties on US$200 billion on imports had been due to start on Aug. 4, but India's Ministry of Finance said on Friday they would be pushed back by six weeks.

New Delhi, incensed by Washington’s refusal to exempt it from new tariffs on steel and aluminum, had originally planned to implement tariffs on U.S. products including almonds, walnuts and apples on June 21.

Tariffs on apples would rise from 50% to 75%, severely impacting trade to what had by May this year become Washington State's number-two apple export market.

India had also planned to increase tariffs on U.S. almonds by 20% and on walnuts by a massive 120%.

Officials from New Delhi and Washington, including U.S. Secretary of State Mike Pompeo and Defense Secretary Jim Mattis, are scheduled to hold a series of meetings including talks with their Indian counterparts in September.
