The office was recently notified by Air NZ in regards to carriage of gun cleaning liquid carried by a passenger with their firearm. The substance was Hoope's No 9 Bore cleaner and was detected in checked baggage due to it leaking.
An investigation has shown that this cleaner is calssified as a dangerous good (flammable liquid). This was determined by looking at the Safety Data sheet (section 14 Transport Information). The UN mumber 1993 shown in the data sheet means this product can only be transported as dangerous goods cargo. This means that when consigned as cargo, it has been packed, documented and checked by trained personnel.
Please be aware if you are intending to travel with any cleaning fluids, to check that they are not classified as a dangerous good i.e if they have a UN number then they will be strictly forbidden in passenger baggage. Should they be found in checked baggage, the passenger will be delayed and asked to explain. As this is a regulatory breach, fines may also be applied.
