I'll take a crack.
It's simple mathematics. If your competitor has a lower tariff or no tariff, but you pay one, they have a competitive advantage in the marketplace and will eat your lunch.
I take the point of the other member, who commented that sometimes we also try to get ahead of the United States and Europe. For example, in respect of the Colombian market, we're very pleased to say that we have a competitive advantage now over the U.S. and they're playing catch-up. But that's the nature of the game, and it's simple mathematics.
Even a small tariff difference can be important. In the case of commodities, for example, a 2%, 3%, or 4% tariff can make a significant competitive difference when you're trying to sell into another market.
