Does anyone have any experience with shipping Kodachome 40 film to the US for processing? I am shipping from Beijing (China) using Fedex, but Fedex doesn't guarantee how it'll be treated at customs. Obviously, there's no point shipping if it's all going to be fogged by x-ray machines. I emailed Dwayne's and was told that because the film is so slow, x-ray is not a problem, but the Kodak website indicates otherwise.
For a slow film like K40, the low dose x-ray machines (as might be used for carry-on baggage) generally don't cause a noticeable issue for one or two passes through the machine. But the exposure is cumulative, and sometimes the machine doses are not that well controlled, so there is still some risk.
But if the film is subjected to the CAT-scan type equipment often used for checked baggage, it will receive a very intense dose of radiation, likely to produce severe fogging.
Shippers like FedEx who use their own planes probably can avoid using x-ray inspection within their own system (they check the package in other ways), but may be unwilling to guarantee that customs or another governmental agency won't insist on an x-ray examination. All you can do is to comply with the FedEx requirements for identifying the shipment as unprocessed film on the airbill, and clearly labeling the outside of the package "do not x-ray". For small, self-contained units like Super-8 film, the customs officials are likely to understand the concern, and inspect the items in other ways.

If you take the film as carry-on baggage, in the USA, the TSA regulations specifically allow requesting hand inspection of professional and motion picture films without x-ray exposure. Overseas, the rules may vary, but having a copy of the TSA rules may help convince them to hand-inspect:http://www.tsa.gov/p...90005198004a860
