How many kilometres does it take for self raising flour to travel to the UK?

The distance self-raising flour travels to the UK can vary widely depending on its origin, such as local production within the UK or import from countries like Canada or Australia. Typically, shipments may cover thousands of kilometers, often ranging from 1,000 to over 10,000 kilometers, depending on the source. However, if flour is produced domestically, it may travel only a few hundred kilometers. Overall, the exact distance would depend on the specific supply chain involved.
