LONDON, Dec 6 (Reuters) - The world is going to need another 50,000 tonnes of tin per year by 2030 to meet a looming surge in demand, according to the International Tin Association (ITA). The country exported 75,000 tonnes of refined tin last year with shipments running 8% higher through the first 10 months of this year. State producer PT Timah needs around two years to develop its existing tin chemical facility and longer to secure markets, Alwin Albar, chairman of the Association of Indonesian Tin Exporters, told a parliamentary hearing. China imported 22,600 tonnes of refined tin in the first 10 months of the year with Indonesian metal accounting for 19,000 tonnes. After peaking at 5,160 tonnes in September, headline LME tin stocks have fallen to 3,075 tonnes with 535 tonnes awaiting physical load-out.
