  • NEW  Amendment to the CWC Regulations and Export Administration Regulations: Addition of Schedule 1A Chemicals & Clarification of the Definition of Production

  • This final rule amends the CWC Regulations (CWCR) and the Export Administration Regulations (EAR) to reflect recent additions to Schedule 1A of the Annex on Chemicals to the CWC, consistent with two decisions adopted by the CWC Conference of the States Parties in November 2019. This rule adds three Schedule 1 chemical families and one individual Schedule 1 chemical to Schedule 1A in Supplement No. 1 to Part 712 of the CWCR and Supplement No. 1 to Part 745 of the EAR.

    This final rule also amends the definition of ..production.. in Section 710.1 of the CWCR to clarify the scope as it applies to declarations regarding the production of Schedule 1, Schedule 2, or Schedule 3 chemicals whereby chemicals that are intermediates, but not transient intermediates, must be considered when determining if a chemical is subject to the declaration requirements in the CWCR.
