That's something for them to decide if they believe that market is worth their while. This is no different than at present when a company could choose to produce something to a different standard for a foreign market or it maybe packaged differently, essentially the same product but with different labeling or sizing. The red tape is already there if you want to trade to a broader set of countries but it's optional, some companies only focus on their domestic market. What we need is to unsuckle ourselves from cheap imports if we want a more diverse and stronger economy. If we don't stop the cheap imports then a company here isn't going to make something that it would otherwise be undercut on.
