I don't know. It's difficult to predict with certainty whether US ports of entry will become overloaded. Global trade and port operations are very complex, influenced by numerous factors. Things like economic conditions, changes in consumer demand, labor issues, weather events, international relations, and yes, even tariff policies, can all impact the flow of goods through ports. I would suggest looking to expert analysis from organizations that track these sorts of things for more informed predictions.
