The volume transacted rose to 102 tonnes, from Tuesday's 63 tonnes. Three-month tin on the London Metal Exchange (LME), which often provides price direction to the KLTM, fell $50 to $6,200 a tonne on Tuesday.
Dealers said Japanese and Malaysian buyers bid for a total of 25 tonnes at the KLTM's open.
Sellers offered 102 tonnes, setting the mark for the day's turnover. "The good buying support checked a further decline in the price," said a trader.
The $10 difference between the falls in Kuala Lumpur and London widened the premium for shipping a tonne of Malaysian tin to Europe. The premium, which takes into account freight, insurance and other costs, rose to $255 a tonne from Tuesday's rate of $245.
