I had no idea about all this craziness, but I have to say, I use USPS unless I need blood plasma shipped to me (I'm using an example of something needed fast, not sure blood plasma is the best example, but you get what I'm saying) I am actually surprisingly loyal to USPS, I feel they really stepped up their game compared to Fed Ex and whatnot, and I refuse to pay those prices if I can help it. The fact that Fed Ex and UPS are gouging further does not surprise me in the slightest.
So, it sounds like completing the form is optional, but perhaps not so much if you want your product? And do they only do this on high end products like electronics or whatnot, like is there a trigger "amount" your product is worth for Fed Ex to decide it wants a secondary, doubled customs fee?
If I ship e-cig equipment out of the country I tend not to label it as such, while creatively labelling it accurately. (An oil atomizer, etc.) Just to make customs easier, I can't believe Fed ex has added this whole new level of trickery. Hmm.
