The Verification Process

Verification exercise.

In principle, the verification process is intended (i) to serve as a confidence-building measure that each and every State Party is meeting its obligations under the Convention, and (ii) to have a deterrent effect on those having the intention to contravene the Convention's provisions.

The first aim of the verification process relevant to the chemical industry is achieved through the mechanisms set out in Parts VI, VII, VIII and IX of the Verification Annex of the Convention.  In essence, the process involves the submission of declarations by the State Party in relation to specified activities taking place in its chemical industry.  These declarations are the basis for carrying out data monitoring on and on-site inspections at the declared facilities on the territory of the State Party to verify that the activities are in accordance with the obligations under the Convention and consistent with the declared information.

The deterrent effect is achieved through a mechanism by which a State Party that has a concern regarding possible non-compliance with the Convention of another State Party can request that a challenge inspection be carried out under the rules set out in Part X of the Verification Annex. This is a unique feature in terms of multilateral disarmament treaties and makes the Chemical Weapons Convention the first international treaty that embodies such a provision.
