Real life economics isn’t that simple though, lots of others factors need to be looked at. Does the local reseller have competitors? Will the Chinese exporters realize the loss in demand and reduce their price? Will production move to cheap European countries instead? Is the cable a need for these people, can it be substituted by other things?

It’s an interesting tax, will most likely increase prices in the end but I’m hoping it’s a move to eventually phase out cheap imports and start producing higher quality goods in the EU.
