Shanghai tin prices dropped on Tuesday from record highs hit in the previous session as growing power cuts in top consumer China sparked worries over downstream demand.
The most-traded November tin contract on the Shanghai Futures Exchange fell 4.5% to 269,430 yuan ($41,667.38) a tonne at 0416 GMT, falling from a record 290,510 yuan-a-tonne record level hit on Monday.
As solder companies and tin chemical producers in parts of China operated at reduced capacity due to electricity usage curbs, demand for refined tin reduced, the International Tin Association's (ITA) Beijing branch said on Monday.
"The price of tin, previously supported by fundamentals, may face greater downward pressure," the ITA added.
Prices of the metal surged 91.5% this year as of Monday's close, backed by pandemic-led supply disruptions in major producing countries and booming demand for electronics.
ShFE nickel dropped 3.2% to 140,900 yuan a tonne, while LME nickel fell 1.4% to $18,690 a tonne.
"The current demand for nickel is strong, but the limited production of stainless steel affects some refined nickel consumption," brokerage Huatai Futures said in a report. "The power curtailment policy affects part of the downstream consumption of nickel."
