The OPCW’s mission is to implement the provisions of the Chemical Weapons Convention and to achieve the vision of a world free of chemical weapons and the threat of their use, and in which chemistry is used for peace, progress, and prosperity. This is including the prohibition of the Development, Production, Stockpiling and Use of chemical weapons and their Destruction. As of today, OPCW has 193 Member States, that are working together to achieve a world free of chemical weapons. For further details on OPCW please go to

The OPCW Member States share the collective goal of preventing chemistry from ever again being used for warfare, thereby strengthening international security. To this end, the Convention contains four key provisions:

  • destroying all existing chemical weapons under international verification by the OPCW.
  • monitoring the chemical industry to prevent new weapons from re-emerging.
  • providing assistance and protection to States Parties against chemical threats, and
  • fostering international cooperation to strengthen the implementation of the Convention and promote the peaceful use of chemistry.

Schedule Chemicals

To implement the CWC, there are identified chemicals for the application of verification measures according to the provisions of the CWC.

One of the most important obligations in the Convention that Malaysia needs to fulfil is to submit the Annual Declarations. Thus, companies involved in activities above the declarations threshold limit related to Scheduled Chemicals and Unscheduled Discrete Organic Chemicals (DOC) must submit their annual declaration to the National Authority. The submission of the annual declaration is mandatory under the CWC Act 2005. Hence, the failure to submit the annual declarations is an offence under the law.
