Sure. I'll do it perhaps a bit generically but give you some specific examples.
Whether we have a trade deal with a country or not, we often face market access issues, and country-of-origin labelling in the U.S. would be a good example of that. We often have market access issues with China.
Perhaps Andrew has the same problem, but in addition to non-tariff barriers—just differences in testing methods or testing standards—we face sanitary and phytosanitary issues that have to do with the fact that we have a biological product, an organic product. Often different countries apply different tolerance levels for pests or pesticides or a low-level presence of genetically modified materials. To the extent that those different approaches reside in another country we're trading to, they pose a trade barrier for us. Whether we have a trade deal or not, often the text of a trade deal doesn't deal with those. Those are the issues that—really, probably more often than not—stop us from trading.
Our negotiators know how to deal with tariffs. They know how to deal with quotas. There are formulas. There are different ways of approaching it. But it's the non-tariff barriers that really cause the major market access issues, because you can be very creative in how you decide to stop another country's product from getting in.
That's why I made one of the other points: we really need to be negotiating 21st century deals that start to get our head around the complexity of these non-tariff barriers and how, perhaps, we start to put in processes and formulas for dealing with those. Really, they have to take place on an international basis.
