What's the 10 digital code for FPGA board that is requested by American Customs?

Hi all, I have bought an FPGA based Development Kit in America, and I want to send it to China, but unfortunately I don’t know the correct 10 digital code for export/import thing, so the board has been held by the costumes officer there.
Could you please tell me the correct 10 digital code for this kind of board, thank you in advance, the address is https://www.census.gov/foreign-trade/schedules/b/#about
