President Donald Trump’s tariff hike on Indian goods took effect Wednesday, doubling duties to as much as 50 percent on products like textiles, jewelry, footwear, furniture and chemicals, Reuters reported.

The move, tied partly to India’s Russian oil purchases, puts thousands of exporters and jobs at risk, especially in Prime Minister Narendra Modi’s home state of Gujarat. India’s Commerce Ministry says it will support affected businesses and encourage them to seek new markets in Asia, Latin America and the Middle East.

A short grace period allows goods already in transit to enter the US at lower rates until September 17.

Washington argues Indian tariffs unfairly restrict US exports, pointing to rates as high as 100 percent on autos and heavy duties on farm goods. India counters its average tariff on US imports is only 7.5 percent, according to Reuters.
