* Dec stocks to rise 4.3 pct from Nov to 3.14 mln T -survey * Output to fall to 1.78 mln T, down 3.6 pct -survey * Exports estimated up 4.7 pct at 1.44 mln T -survey * Malaysian Palm Oil Board data due Jan. 10 By Emily Chow KUALA LUMPUR, Jan 4 (Reuters) - Malaysia's palm oil stocks are expected to have hit a 19-year high for end-December, surpassing the 3 million-tonne mark as production levels exceed exports, according to a Reuters survey. Stockpiles are expected up 4.3 percent from the previous month to 3.14 million tonnes, based on the median estimate of seven planters, traders and analysts. This would mark a seventh straight month of increase and Malaysia's highest stockpile levels since January 2000, according to Refinitiv Eikon data. MYPOMS-TPO Inventory gains could weigh on benchmark palm oil prices , which have recovered from three-year lows touched in November below 2,000 ringgit a tonne. Palm edged up 0.1 percent on Friday at 2,152 ringgit ($519.93) a tonne. "We think the market will still be carrying high stocks all the way until end-March," said a Singapore-based trader. "If we can't draw down stocks by end-March, after going through the low production cycle, it would be extremely difficult to draw stocks thereafter as production recovers," he said, adding that he has observed a pickup in exports to key markets China and India. The survey showed Malaysia's December exports are expected to have risen 4.7 percent from the previous month to 1.44 million tonnes, which would be the first gain after two months of decline. MYPOME-PO Demand for palm oil, the world's most commonly used edible oil, could further rise in the coming months following India's move to cut palm oil import taxes. India, the world's largest importer of edible oils, earlier this week said it would lower the duty on crude palm oil imports to 40 percent from 44 percent, while a tax on refined oils was cut to 50 percent from 54 percent. Additionally, Malaysian shipments of refined palm oil will be taxed at the lower rate of 45 percent, compared with the earlier 54 percent. The poll showed as well that December production is likely to have declined 3.6 percent to 1.78 million tonnes, which would be its second straight month to fall. MYPOMP-CPOTT Palm oil production usually tapers off at year-end before seasonally rising towards the end of the first quarter. Official palm oil data will be published by the Malaysian Palm Oil Board after 0430 GMT on Jan. 10. The median results from the Reuters survey put Malaysia's consumption in December at 279,252 tonnes. Breakdown of December estimates (in tonnes): Range Median Production 1,720,000 - 2,000,000 1,779,000 Exports 1,356,559 - 1,500,000 1,440,000 Imports 50,000 - 110,000 70,000 Closing Stocks 3,067,128 - 3,309,842 3,136,736 * Official stocks of 3,006,988 tonnes in November plus the above estimated output and imports give a total December supply of 4,855,988 tonnes. Based on the median of exports and closing stocks estimate, Malaysia's domestic consumption in December is estimated to be 279,252 tonnes.
