NEW DELHI, Feb 27 (Reuters) - London copper prices inched lower on Thursday, tracking a firmer dollar as uncertainty lingered around U.S. President Donald Trump's tariff plans. Three-month copper on the London Metal Exchange (LME) CMCU3 edged 0.2% lower to $9,442 a metric ton as of 0211 GMT, after rising in the previous session. The U.S. dollar firmed above an 11-week trough as vague pledges from Trump to impose tariffs on Europe, and further delays to levies planned for Canada and Mexico stoked uncertainty. USD/ A stronger dollar makes commodities priced in the U.S. currency more expensive for buyers using other currencies. "Looking ahead, March will be a tariff-packed period for the markets, as a hike in aluminum, steel and general "reciprocal" tariffs are all on deck," said Marex consultant Edward Meir. "We sense further turbulence as these U.S. tariff increases will almost certainly be matched by America's trading partners, darkening global growth prospects."
