SAO PAULO, Aug 8 (Reuters) - Brazilian logistics

operator Rumo ( RUMOF ) has clinched a deal with a local

subsidiary of U.S. agribusiness major CHS Inc ( CHSCL ) to build

a new grains and fertilizer terminal at the port of Santos.

CHS and Rumo ( RUMOF ), which is controlled by conglomerate Cosan ( CSAN )

, will share control of a joint venture responsible

for developing the new asset in the largest port in Latin

America, according to a securities filing late on Wednesday.

The terminal will have an annual capacity of up to 12.5

million metric tons, including 9 million tons of grains and 3.5

million tons of fertilizers, Rumo ( RUMOF ) said.

Brazil is a top global supplier of grains such as soybean

and corn but imports much of its fertilizer needs.

The companies did not detail how much they will invest in

the terminal. The start of construction is subject environmental

licensing and legal and regulatory approvals, the Brazilian firm

added.
