Chemical Weapons (Prohibition) Regulations 1997

1 The amount of the chemical is the weight of the chemical.

2 The weight of a Schedule 2 chemical, mentioned in Part A of Schedule 2 to the Convention and designated with an ‘*’, is to be worked out as accurate to the nearest 100 grams.

3 The weight of a Schedule 2 chemical, mentioned in Part A of Schedule 2 to the Convention but not designated with an ‘*’, is to be worked out as accurate to the nearest kilogram.

4 The weight of a Schedule 2 chemical, mentioned in Part B of Schedule 2 to the Convention, is to be worked out as accurate to the nearest 0.1 tonnes.

5 However, for a mixture containing:

(a) 0.5 percent or less by weight of a chemical mentioned in Part A of Schedule 2 to the Convention; or

(b) 30 percent or less by weight of a chemical mentioned in Part B of Schedule 2 to the Convention;
the amount of the chemical is zero.

6 If the chemical is produced as part of a mixture—to work out the percentage of the chemical in the mixture by weight, the following components of the mixture are to be disregarded:

(a) any liquid or gas, the main function of which is to act as a carrier in a chemical reaction process that produces the chemical; and

(b) if a feedstock gas is incompletely reacted in a chemical reaction process that produces the chemical—the gas that did not react.

7 In addition, for working out the total amount of the chemical that is consumed in a process, an amount of the chemical recovered from the process and recycled through it is to be included in the total amount only once.
