London copper firmed on Tuesday, holding near the more-than-one-week high hit in the previous session, aided by recent US tariff exemptions and optimism that top consumer China will launch additional stimulus measures to bolster economic growth.
The benchmark three-month copper on the London Metal Exchange (LME) was up 0.1% at $9,192.5 a metric ton, as of 0252 GMT.
In the previous session, the contract hit its highest level since April 4.

The pause on import fees on consumer electronics provided a temporary respite for markets after Trump’s trade policies sowed deep uncertainty, said Daniel Hynes, a senior commodity strategist at ANZ Bank.
