25% seems too steep. And if that's really what's needed to price-in the costs of any unfair trade practices, then it should be phased in for the market to adapt (i.e. to give manufacturers time to relocate, before facing the full effect of it).
I'm somewhat ambivalent on tariffs, overall. In some cases, they're a necessary measure, but the problem is that eventually the costs will be passed on to the customer. When they are used, they really need to be phased in, over time. That minimizes collateral damage while still addressing structural market imbalances.
With all that aside, I'm glad to hear these exemptions have been extended, as they would have only served to further fuel inflation. Once inflation is firmly under control, we can take another look at tariffs.
