Beiersdorf's organic sales, excluding exchange rate effects as well as the impact of acquisitions and divestments, rose to 7.1 billion euros (6.28 billion pounds), up from 6.8 billion a year earlier, the German consumer goods maker said on Monday.

The Hamburg-based company cited particular strength at its consumer segment - which includes brands like Nivea, Eucerin, Hansaplast, and La Prairie - and its adhesives unit Tesa.

Beiersdorf has performed strongly against rivals Unilever, the maker of Dove products, and Britain's Reckitt Benckiser.

"While the global markets are expected to remain volatile and challenging, we have good reason to be cautiously optimistic as we start into 2018," said Chief Executive Officer Stefan Heidenreich.

RBC Capital Market said in a note to investors that sales surpassed its expectations.

Beiersdorf will announce final figures on March 1.
