Chemical Weapons Convention Regulations: Reducing the Concentration Level Above Which Mixtures Containing Schedule 2A Chemicals Are Subject to Declaration and Reporting Requirements

The Bureau of Industry and Security (BIS) is publishing this final rule to amend the Chemical Weapons Convention Regulations (CWCR) to reduce the concentration threshold level above which mixtures containing a Schedule 2A chemical are subject to the declaration requirements that apply to Schedule 2A chemical production, processing and consumption under the Chemical Weapons Convention (CWC). This final rule also amends the CWCR to reduce the concentration threshold level above which mixtures containing a Schedule 2A chemical are subject to the declaration and reporting requirements that apply to exports and imports of Schedule 2A chemicals under the CWC. These regulatory amendments bring the CWCR into further alignment with guidelines adopted by the Organization for the Prohibition of Chemical Weapons (OPCW) Conference of the States Parties (CSP), which established a low concentration limit for Schedule 2A chemicals.
