* Also up 18 pct from month before
* China making ethanol to erode corn stockpiles
* Ethanol imports slow to trickle
(Adds comment, background)
BEIJING, May 23 China's ethanol exports soared
in April from the same month the year before and imports slowed
to a trickle, the latest sign that Beijing's drive to ramp up
local output is upending trade flows in the world's
fastest-growing biofuel market.
China has been pushing to erode a domestic glut in corn
supply through steps such as using the grain to churn out
ethanol or other products like biodegradable plastics.
The country exported 13,540 cubic metres of ethanol in
April, up over 1,000 percent from a year earlier and 18 percent
higher than the month before, data from the General
Administration of Customs showed on Tuesday.
Traders said the reintroduction of an export rebate last
year had revived foreign sales.
"This year there's a tax rebate of 13 percent and processors
have subsidies," said a manager familiar with ethanol trade at
trading company Zhejiang Materials. He declined to be identified
as he was not authorised to speak with media.
In the first four months of the year, ethanol shipments
jumped to 42,701 cubic metres, exceeding the total for the whole
Saudi Arabia remained the top buyer of the fuel in April,
accounting for 66 percent of cargoes.
Meanwhile, China imported just 23 cubic metres of ethanol
last month, as a big hike in taxes at the end of 2016 hit
