Why was my shipping marked so high?

I purchased $23 worth of boards and until recently, had much cheaper shipping options. After temporary tariff changes in america, (which de minimis package tariffs were repealed) I could pay very high shipping rates with anyone except for fedex and DHL. I selected FedEx because it seemed the same price as DHL. I was marked up $172.69 for shipping, why is this? This does not seem right, especially for the supposed price of the boards.
