I used to argue with US Customs and their related authorities, but I discovered that it is a futile exercise and that complying with their (often ridiculous) demands saves a lot of hair pulling and other such frustration.

Practically all of our shipments to the US now reach their destination by 10:30am the next day. To help ensure this we enclose no less than twelve pieces of paper with each package. It's official - the US Government are screwing the environment :-)
