LME tin retreats from recent record highs on speculative selling triggered by news reports that Indonesia's PT Koba Tin has been granted an export license, says LME broker. Indonesia produces around one third of global tin supply. The market had been awaiting Koba Tin's export license as it is the country's second largest producer. Tin should find good support around $14,135/ton, the low from last week, trader adds. LME tin trades at $14,652/ton, -2.3% from Tuesday.
