UK trade figures are widely published and on the net. A quick google turns them up. Why bother to link when it is just as quick to put the question in google?

For a start, see http://www.economywatch.com/world_economy/united-kingdom/export-import.html
The export diagram is a little hard to read, but the USA receives 33.5 billion pounds in exports, Germany 24.8 billion, etc.

Interesting is that UK's largest export is medicaments, followed by petrol, and the biggest import category is manufactured goods.
