<h1>US 50% tariff and additional 25% Russia-linked duty raising duties on Indian imports; adviser signals limits on cross-border AI services</h1> A 50% tariff regime announced by the US President, including an additional 25% duty applicable to imports tied to purchases of Russian crude oil, constitutes a unilateral change to US tariff policy; its operative effect is to raise duties on affected imports from India, penalize purchases of Russian oil and create trade-distorting economic pressure on bilateral commerce. Separately, a senior US trade adviser publicly challenged cross-border provision of AI services-asserting that US-hosted AI services used by foreign users impose costs on Americans-which, as stated, signals an intent to treat cross-border digital service provisioning as a trade or regulatory issue to be addressed.
