Don't Get Caught Out by Dangerous Goods
Every year, millions of parcels are sent inside UK and to destinations worldwide. While many packages are completely innocuous, a proportion have the potential to pose any adverse health and safety risk and possess security implications. - Hazardous Materials
There are certain goods that people would identify immediately being a potentially dangerous and it wouldn't come as a surprise to find them over a prohibited list. Guns, human remains, meat, living creatures and explosive materials are all likely candidates to belong to the prohibited category when it comes to international parcel delivery.
Other prohibited items are perhaps not quite as obvious to spot. Money, stamps which haven't been franked, lottery tickets, wine and aerosols are all goods that are prohibited by some shipping companies. Anyone sending prohibited goods using a carrier, whether they realise it's banned or not, risks having their consignment cancelled immediately.
Some international shipping companies will carry items classed as dangerous goods, but often there are numerous of conditions attached. You'll almost certainly have to pay reasonably limited for sending products which are potentially dangerous and they're going to have to be packed and labelled correctly.
The rules differ from courier to courier as well as depend on which country the goods are heading for, so it is always recommended to get advice before booking a delivery in order to avoid inconvenience and disappointment.
Not be tempted to send very dangerous goods without declaring them with the aspiration they will pass through undetected. You will find major health and safety implications and if for example the item is flammable and you don't realise, you are putting other people at risk.
Customs in every country will differ therefore even if a certain item is allowed, it should take to be labelled in a certain way or have specific documents. If your documents are not so as there is the risk the package will be sent back and the international courier will be powerless to do anything about it. - Hazardous Materials
