In crossing borders, for us there are multiple parties involved. The first and most important is the border services agency. They perform a very important job in terms of what is admissible into a country.
Unlike the commercial stream, the postal stream requires that all items be presented to customs for their inspection. That inspection could include an X-ray. It could include a secondary inspection, unlike the commercial stream. In the commercial stream, it's a known shipper, and the known shipper therefore has a lower risk profile. They will only pick out the items they actually want to see. It's a very small fraction. On the postal side, it's more of an anonymous type of sender going to an anonymous receiver.
The cross-border time lag is very important and is starting to get tighter and tighter. We're recognizing the importance of the customs inspection process. One of the things we will be looking at in working with other posts and customs authorities is how to leverage data better. We will be looking at advance data to be able to streamline those processes so that they can see in advance what's coming to them. They don't need to sit on and hold everything and inspect everything or X-ray everything.
Certainly one of the things we're seeing with certain countries, and China would be one of them, is that when items are coming in, they want to see all of them. They want to X-ray everything. They're obviously looking for certain items in their inspection under their risk profiles. There are opportunities to streamline that, and we are working with other posts and customs authorities to do that.
