I recently shipped a wattmeter to Australia via USPS International
Priority Mail. Other than sitting in Chicago's International Outgoing
Parcel Customs Unit for two weeks (!), all went fine. Once it left
O'Hare via Air Mail, it arrived in Australia quickly and cleared
Australian customs in one day, and delivered to the buyer the following
day. Why it was delayed so long in outgoing US customs is anyone's
guess. And, yes, the custom form was correctly filled out.
