The world’s top tin exporter, Indonesia, are likely to ship as much as 5,000 tonnes of the metal during the month of December, bringing their total exports up to around 86,000 tonnes for the calendar year.

Smelters in Indonesia’s main tin-producing region of Bangka island stopped tin ingot shipments from Oct. 1 as they look to boost the price of the metal, however the export ban faltered in December despite a strong showing in November.

“There are at least seven tin smelters who have been exporting refined tin in December,” Rudy Irawan, chairman of Indonesia Tin Association (ITA), told Reuters.

“If we calculate the six smelters together with PT Timah’s exports in December, then we may come to the total export figure of 5,000 tonnes,” he said.
