These are just some of the most recent examples involving the UK. For example, we export 4,400 tonnes of ice cream to Italy, only to re-import 4,200 tonnes. We import 22,000 tonnes of potatoes from Egypt whilst exporting 27,000 tonnes back again. Then there are the 5,000 tonnes of toilet paper heading from the UK to Germany, with over 4,000 tonnes returning, and 10 tonnes of ‘gums and jelly’ sweets going back and forth to Thailand. At the last count, 117 tonnes of ‘sweet biscuits, waffles and wafers, gingerbread and the like’ (to use the category used by trade statisticians), came into the UK, rumbling passed 106 tonnes headed in the opposite direction.
