However, in recognition that alternatives might not be available for all uses of ozone-depleting substances, consumption of controlled substances are permitted for the following uses *:

Group of Controlled Substances	Controlled Substance	Purpose
1	Carbon Tetrachloride	(a) essential use (b) feedstock (c) analytical standard
2	Methyl Chloroform	(a) essential use (b) feedstock (c) analytical standard

Glossary Term

Essential Uses
An approved exemption from the total phase-out of an ODS that is granted by the Meetings of the Parties on a case-by-case basis (exempted category) under the condition that the ODS is either necessary for health, safety or for the functioning of society and no acceptable alternative is available. For example, a global exemption has been granted for laboratory and analytical uses.

Glossary Term

Feedstock
The use of an ODS in the manufacture of another chemical causing the ODS to become completely transformed in the process. For example, carbon tetrachloride is commonly used in the production of CFCs.

Glossary Term

Preshipment Applications
Preshipment applications are non-quarantine applications of methyl bromide applied within 21 days prior to export to meet the official requirements of the importing country or existing official requirements of the exporting country. Official requirements are those which are performed by, or authorized by, a national plant, animal, environmental, health or stored product authority.
