Once you have determined that your item is classified under a specific ECCN, you must use the information contained in the "Reason(s) for Control" section of that ECCN in combination with the "Commerce Country Chart" (see Supplement 1 to Part 738 of the EAR) to decide whether a license is required. If there is an "X" in the box for the Reason for Control and destination country, a license is required from BIS, unless a license exception is available. If there is no "X" in the box, a license is not required unless your proposed export is to an embargoed country, to an end-user of concern, or in support of a prohibited end-use, in which case you may be required to obtain a license.
