State-run Taisugar, the island's only refiner, which relies mainly on imports to meet its needs, said interest from buyers from the United States, Japan and Europe had been strong.
"As international prices have risen, buyers have started placing orders as they look at the high quality of Taisugar's product," a spokesman for the company said, adding it hadn't exported major quantities of sugar for 30 years.
The Indonesian-bound cargo was slated for shipment later this week, the executive said.
Taiwan opened its market in February to private businesses to import sugar free of quota restrictions, leading to a rush by new importers, depressing prices.
Taiwan's annual demand for sugar is around 600,000 tones, of which 450,000 tonnes is supplied by Taisugar, which now only produced 70,000-80,000 tonnes domestically, executives say.
The executive said it was hoping to maximise its refinery's utilisation rate and boost profits now that the market is liberalised, although the executive declined to say how much the company hoped to export each year.
The island imported 473,417 tonnes of sugar in the January to August period this year, up 14.7 percent over the same period in 2004, government data showed.
