An experimental chrome extension to overlay Trade Tariff information on Sainsbury's online in the form of food-health style labelling. The output of a late night and early morning at the DFID Data Challenge.
Data comes, in a couple of different ways, from http://worldbank.org.
I chose Sainsbury's because they seem more willing (than Tescos at least) to display country of origin - for which I commend them. It still works best for goods like posh coffee where there's a marketing advantage for proclaiming the origin country.
You can get an installable pack of Tariffic but you probably don't want to since its so wonky.
Next steps? Implement an alternative display for products with no listed country of origin - perhaps something which says.
"Warning! No stated Country of Origin. Don't put it in your mouth if you don't know where its been."
