The cold war period saw significant development, the production and stockpiling of chemical weapons. In the 1970s and 80s, an estimated 25 states developed chemical weapons capabilities. But since the end of World War II, chemical weapons have only been used in a few cases, notably by Iraq in the 1980s against the Islamic Republic of Iran. Chemical Weapons Stockpiles – States Parties must declare all chemical weapons stockpiles divided into three categories: there are several agreements that overlap with the CWC`s mandate. For example, the Australia Group (AG) coordinates CW-related export controls and encourages the exchange of information between its 32 member countries. The Proliferation Security Initiative aims to prevent the transfer of all weapons of mass destruction (WMD), including chemical weapons. More broadly, UN Security Council Resolution 1540 requires all states to take all possible measures to prevent the proliferation of weapons of mass destruction. In some cases, such as the Australia Group, countries face conflict between mandates. For example, some states complain that the GA restricts free trade in chemicals and chemical processes to CWC members, who have a good reputation with the OPCW and CWC.

(a) toxic chemicals and their precursors, unless they are intended for purposes not prohibited by the Convention as long as the species and quantities are compatible with those purposes; (b) ammunition and devices specially designed to cause death or other damage resulting from the use of such munitions and devices due to the toxic properties of the toxic chemicals referred to in point (a); (c) equipment specially designed for use in direct connection with the use of ammunition and devices referred to in point (b). At the end of 2019, 70,545 tons of chemical weapons were destroyed out of 72,304 tons (97.51%). More than 57% (4.97 million) of chemical munitions and containers were destroyed. [22] The CWC requires states parties to declare in writing to the OPCW their chemical weapons stockpiles, chemical weapons production facilities (CWPF), relevant chemical industry bodies, and other weapons-related information. This must be done within thirty days of the entry into force of the Convention for each Member State. The health authority is the Estonian national authority of the CAC. Among our main tasks are informing companies and other authorities about the CWC, collecting data from the Estonian chemical industry, preparing national declarations to the OPCW and accompanying OPCW inspections in Estonia. The destruction of category 1 chemical weapons must begin within two years of the entry into force of the CWC for a State. . . .
