Trump tariffs on India: US Donald Trump has imposed a 50 per cent tariff on Indian imports, effective 27 August, citing India’s oil trade with Russia as a national security threat. The new duties double the earlier 25 per cent levy but exclude smartphones, computers and electronics. That exemption shields Apple’s growing iPhone exports from India, which now account for most US sales. India has overtaken China as the top iPhone supplier, but with Washington reviewing semiconductor imports, the exemption may only be temporary.
