Hello,  Here are my issues and how they were resolved.  My bank does do international wire transfers for a $30 dollar fee (in a business account).  My first two attempts failed because the bank code had extra X's at the end--took a while to figure that out, but eventually did.  Then it failed twice because I did not have an adequate street address for the company.  Canaan promptly provided this when I asked.  Success--bank said it transferred $2018, but Canaan only received $2008--an additional fee was charged somewhere--my guess it was sent through an intermediate bank (Citi NY?) and Canaan got the fee charge.  Fortunately Canaan waived the fee.  Then I got a letter from Fedex about 9AM about the shipment--not enough info to classify, what are they?  Where were they made?  I replied the A721's are specialized computers and the control unit is just a computer like the Rasberry Pi and they were all made in China.  I also sent links to the A721 and controller pages from the site.  In addition, I said these are similar in function to the Bitmaintech Antminer s9.   Released from customs later in the day I got the customs email.  They are to arrive Monday the 5th, which is 5 days after the wire transfer went through.  I still don't know how they were classified and how much duty I will get billed for, or how much of a fee Fedex will charge for all this.    My order was for two A721 and one controller.
