LONDON, Sept 21 (Reuters) - British home improvement group Kingfisher's stock levels of wood, cement and some products that contain semiconductor chips are below target levels, its boss said on Tuesday.

"Everybody in the world is looking for timber ... we are looking for cement and there is a shortage of chips for computers and it impacts some of our product," Chief Executive Thierry Garnier told reporters after the firm published first half results.

However, he said that generally he was "pretty happy" with overall product availability as the group had placed orders significantly ahead of peak trading periods.

"Today we are in a good place," he said. (Reporting by James Davey; editing by Michael Holden)
