My batch 5 was stuck in customs as well because Bitmain overstated the value at over $7000 per miner. I just had to call FedEx and email them a screen shot of my order and state that the value was overstated due to human error. They'll also want to know what the miner does. This explanation got it released right away,"This particular item is a collection of computer processors called ASICs that perform a specific computational task. Alone, this component does nothing. Once I assemble other pieces and attach the ASICs it solves complex computer math problems. In the most simplest of terms, it is just a computer component."

Hope this helps.
