Passport renewal update: My express mail package is sitting in U.S. customs!

A quick update!

On July 8th, I sent out my renewal-by-mail of my U.S. passport. (See this post.)

The package arrived in San Francisco on July 10th, and looks to have been sitting in customs all week?

Here is the last update:

Your item cleared United States Customs at 3:15 PM on July 10, 2010. Information, if available, is updated periodically throughout the day. Please check again later.

So which is it? Is it still in the Customs office, or is it on the delivery truck?

Why would a package addressed to “U.S. Embassy Tokyo, Unit 9800, Box 114, APO AP 96303” be sitting in Customs anyway? Isn’t it pretty clearly a passport renewal? [Update: “Surprise, surprise!” as Jim Neighbors Nabors used to say. I got a call from an Embassy representative earlier today who told me I should not use that address, since I am not in the U.S. military!]
