CHICAGO, Dec 9 (Reuters) - Following are U.S. expectations for the resumption of grain and soy complex trading at the Chicago Board of Trade at 8:30 a.m. CST (1430 GMT) on Tuesday.

NOTE: The U.S. Department of Agriculture will release its monthly supply-demand report at 11:00 a.m. CT (1700 GMT).

WHEAT - Down 2 to 3 cents per bushel

• Wheat edged down for a third day, with Argentina's announcement that it will lower export taxes on major grains underscoring international competition.

• Traders are positioning ahead of the USDA'S report that will be released later in the day. Market players are expecting the USDA to raise export estimates for wheat.

• CBOT March soft red winter wheat WH26 last traded 2-1/2 cents lower at $5.32-1/4 per bushel. K.C. March hard red winter wheat KWH26 last traded down 1-1/2 cents at $5.25 a bushel. Minneapolis March spring wheat MWEH26 last traded 1-3/4 cents higher at $5.73 a bushel.

CORN - Steady to up 1 cent per bushel

• Corn ticked up after a two-session fall, supported by healthy demand for U.S. exports.

• Trade has been thin ahead of the supply-demand report, where the USDA is expected to leave corn exports unchanged.

• CBOT March corn CH26 last traded 3/4 cent higher at $4.44-1/2 a bushel.

SOYBEANS - Down 3 to 4 cents per bushel

• Soybeans tipped lower to hold at their lowest since late October amid market doubts about the scale of Chinese demand for U.S. soybeans under a bilateral trade truce, and on expectations that large South American production will keep the market well supplied.

• China does not appear to be buying as much soy as U.S. officials said it would, and Brazilian soybeans are cheaper than U.S. supplies, he said.

• Chinese trade data showed that the country is on track to import a record amount of soybeans this year, much of it from Brazil.

• CBOT January soybeans SF26 last traded down 4-3/4 cents to $10.89 a bushel.
