[F1 LIST OF DUAL-USE ITEMS (referred to in Article 3 of this Regulation) U.K.

This list implements internationally agreed dual-use controls including the Australia Group, the Missile Technology Control Regime (MTCR), the Nuclear Suppliers Group (NSG), the Wassenaar Arrangement(1) and the Chemical Weapons Convention (CWC)(2).

GENERAL NOTES TO ANNEX I

1.

For control of goods which are designed or modified for military use, see the relevant list(s) of controls on military goods [F2 in Schedule 2 to the Export Control Order 2008]. References in this Annex that state "SEE ALSO MILITARY GOODS CONTROLS" refer to the same lists.

2.

The object of the controls contained in this Annex should not be defeated by the export of any non-controlled goods (including plant) containing one or more controlled components when the controlled component or components are the principal element of the goods and can feasibly be removed or used for other purposes.

NB: In judging whether the controlled component or components are to be considered the principal element, it is necessary to weigh the factors of quantity, value and technological know-how involved and other special circumstances which might establish the controlled component or components as the principal element of the goods being procured.

3.

Goods specified in this Annex include both new and used goods.

4.

In some instances chemicals are listed by name and CAS number. The list applies to chemicals of the same structural formula [F3 (e.g., hydrates, isotopically-labelled forms or all possible stereoisomers)] regardless of name or CAS number. CAS numbers are shown to assist in identifying a particular chemical or mixture, irrespective of nomenclature. CAS numbers cannot be used as unique identifiers because some forms of the listed chemical have different CAS numbers, and mixtures containing a listed chemical may also have different CAS numbers.
