Updates have been made to US Export Controls. The Bureau of Industry and Security (BIS) is publishing this final rule to amend the Export Administration Regulations (EAR) to implement the understandings reached at the September 2009 plenary meeting of the Australia Group (AG). This rule also amends the EAR to implement a decision recommended at the 2009 AG Plenary that was adopted under the AG intersessional silent approval procedures in October 2009. BIS also published a final rule in the Federal Register on Friday, December 11, 2009, that revised the EAR by amending entries for certain items that are controlled for national security reasons in Categories 1, 2, 3, 4, 5 Part I (telecommunications), 5 Part II (information security), 6, 7, 8, and 9; adding new entries to the Commerce Control List, revising reporting requirements, and adding and amending EAR definitions. That final rule contained errors that affected Export Control Classification Numbers 1A004 and 5A001. This document corrects these errors. The following Categories are affected: 1 and 2.
