Copper futures settled down on Tuesday due to concerns surrounding US President Donald Trump's potential tariffs. US President Donald Trump vowed to hit the European Union with tariffs and said his administration was discussing a 10% punitive duty on Chinese imports probably from February because fentanyl is being sent from China to the US via Mexico and Canada. But a weaker dollar makes copper less expensive for other currency holders. Meanwhile, investors were awaiting next week's FOMC meeting and US PCE data.
Copper futures for March delivery lost $0.0275 to settle at $4.3410 a pound on the Comex metals division of New York Mercantile Exchange. Copper on the London Metal Exchange was up by 0.10 percent at $9,284.50 a ton.
