.1 after production, the unpacked material shall be subject to weathering (stored under cover, but in the open air) for a minimum period of 14 days before being packaged for transport; or
.2 after pyrolysis, steam and cooling shall be applied to the unpacked material and the material shall be packed under an inert gas atmosphere (e.g. nitrogen); packages shall then be stored under loose cover or in the open air for a minimum of 24 hours before transport.

.5 The material shall be packed into packagings only when the temperature of the material does not exceed 40°C on the day of packing.

.6 When stowed in a cargo transport unit, minimum headspace in the CTU of 30 cm shall be maintained, and:
