Although certain Dangerous Goods (such as dry ice used as a refrigerant for non-dangerous goods items, or those meeting the requirements for Dangerous Goods in excepted quantities) may be transported without a Dangerous Goods shipper’s declaration, they are still classified as Dangerous Goods according to the regulations. Thus, they must be declared on the airway bill, and handled and transported according to the instructions within the
Air Navigation Order and ICAO Technical Instructions for the Safe Transport of Dangerous Goods by Air.
Authorisation from the State of the Operator is required for airlines intending to transport such Dangerous Goods. The airline will also be required to apply for a Dangerous Goods permit from CAAS to transport such Dangerous Goods to and from Singapore.
