  • NEW  CY 2020 "Change in Inspection Status" -- "CIIS" Declarations -- for Unscheduled Discrete Organic Chemicals (UDOCs) are due by December 16th (postmarked)

  • IF your UDOC facility is currently declared and subject to inspection based on activities that occurred during CY 2019 (i.e., as declared in your CY 2019 Annual Declaration on Past Activities (ADPA) or UDOC No Changes Certification) and IF your facility will not this year in CY 2020, synthesize more than 200 metric tons of UDOCs (the inspection threshold), you should submit a "Change In Inspection Status" Form (CIIS Form) to TCD by December 16th. Submission of a CIIS Form will avoid a possible inspection of your facility during the first 3 months of CY 2021, before the United States submits the 2020 ADPA to the Organization for the Prohibition of Chemical Weapons (OPCW).

    Also, if your UDOC facility shutdown or ceased declarable activities during CY 2020 (and did not synthesize more than 30 metric tons of an individual PSF chemical or 200 metric tons aggregate of all UDOCs), you may submit a CIIS Form to notify TCD of the status change of your facility (complete Question B.7). TCD will notify the OPCW on the status change of your facility to ensure an inspection does not occur during the first three months of CY 2021.

  • NEW  Declaration Submissions:

  • Due to the Covid-19 pandemic, we are accepting declarations via email as a PDF attachment. Please email your PDF declaration to

  • Global Chemical Industry Compliance Program (GC-ICP): A handbook to assist companies in determining if their chemical is subject to declaration/reporting under the CWC and other administrative elements, such as corporate commitment statement and recordkeeping. [PDF]


    Ensure an effective treaty compliance system by:

    • Assisting industry towards compliance with the CWC.
    • Maximizing the protection of confidential business information.
    • Minimizing burdens and costs to facilities.
    • Seeking equitable international implementation.
