Live Animal Label – when live animals are transported by air, specific regulations must be met. A green or red ‘Live Animals’ label or ‘Laboratory Animals’ label/tag is mandatory on all live animal consignments. ‘This Way Up’ labels/tags are also mandatory.
Both the ‘Live Animals Label’ and ‘This Way Up’ label must be placed on all four sides of the container whenever possible, ensuring that any ventilation is left uncovered.
