Imp Hannah Export classification


I have just (minutes ago) been told by that 4 Hannah development boards bought from SmartMaker cannot be exported to South Africa. It seems the items have been classified under control code 5A002.

What is this about. I have previously bought Hannahs from SmartMaker and had them shipped to South Africa, no problem.

Is there any way that you can help with information that will correct the situation to enable MyUs to proceed?
