The best way to explain this is to use the example of the Fuego dance shoes: We order our dance shoes through a retailer who Production sites in Asia booked. These places are not always available immediately. For example, you have to wait 30 days to get a space and only then can you start production. Production then takes another 60 days and then you suddenly get the message: all the goods can now be picked up. But that's where the Madness.
Conflicts like the one in the Middle East influence Transportation routes enormous. Rail transportation is currently not an option, ships take over 100 days - and that is not only slow, but also expensive. So often the only option is air transportation, which Expensive and not so sustainable as we would like it to be. Large volumes have to be split up, routes adjusted and customs documents submitted on time. Unfortunately, new problems can arise at any time. With the Fuegos, for example, we had to repack everything because the cardboard packaging was wet - we lost a whole day as a result. Then there were missing documents for the customs declaration in China, which meant a further two days delay and everything was pushed back even further.
What sounds simple is in reality a new problem to be solved every day. Puzzle with countless last-minute changes.
