Posts want to process and deliver international mail and packages securely and on time.
And Customers can rely on Posts’ affordable and reliable service to deliver their packages – but they need to help them, too.
Posts can deliver all sorts of things. But there are dangerous goods and prohibited items that simply cannot travel through the international postal network.
Dangerous goods can cause harm to people, including customers or postal, customs and airline staff, and cause material damages. Prohibited items also include dangerous goods, but also valuables, obscene materials, counterfeit materials or other items that some countries simply don’t accept on their territory.
As always, customers must check the rules before sending a package or a parcel. Not only will keeping the content safe prevent harm or danger to people, but safe mail will be processed more efficiently and delivered more quickly.
Check before sending!
This is particularly important as packets and parcels traffic continues to increase, and global authorities urge Posts, airlines and customs officials to better screen what they process and transport.
Posts processed 6.7 billion parcels in 2013 alone. Traffic of international packages went up to 67 million items, growing by 5.8 per cent over the previous year.
Help Posts deliver your packages efficiently and safely, and check the content of your parcel or package before sending it.

Can I send perfume by international mail?
No. Perfumes can be flammable and are prohibited from being sent by international mail.
Other cosmetics such as manicure goods or nail polish remover are also considered dangerous.
Why can perfumes travel in a person’s checked luggage? Why is this different from travelling in a parcel?
Perfume normally contains flammable liquid and is therefore classified as dangerous goods. Dangerous goods are forbidden from carriage on aircraft by passengers or crew, either as, or in, carry-on baggage, checked baggage or on the person.
There are, however, exceptions for certain consumer articles used in dressing or grooming (including perfume) and medical necessities.
These articles are generally permitted in very small quantities, provided certain requirements are met, thereby reducing the risks posed.
Can I send medicines and drugs through the mail?
It depends. If medicines and drugs contain alcohol or are packed in dry ice, they are prohibited from entering the international mail stream.
However, commonly used medicines such as Ibuprofen and antacid tablets are admissible. Check with your Post or Customs before sending any medication through the mail.
Can I send a device containing lithium batteries abroad by post?
Posts can accept packages containing devices equipped with lithium batteries under certain conditions.
First, the Post in question must be authorized by the national civil aviation authority to transport packages containing lithium batteries. Click to see the list of Posts that have received such authorization.
Secondly, if a Post can carry packages containing devices with lithium batteries or cells, these must be installed in the devices. Packages must not carry more than four lithium cells or two batteries.
Strong outer packaging is required, and the contents of a parcel must be properly packaged to prevent shifting and/or damage to contents during the transport.
Why can passengers carry devices containing lithium batteries with them in the cabin of an airplane, but there are all sorts of rules about lithium batteries and cells traveling by international post?
Lithium batteries are considered dangerous goods because they have the potential to overheat and catch fire.
In accordance with the International Civil Aviation Organization’s Technical Instructions provisions for dangerous goods, passengers and crew can carry portable electronic devices containing lithium batteries and spare batteries for these devices in the cabin.
The provisions include size limitations and measures to be taken to prevent short circuit or unintentional activation. The risk these articles pose is reduced by the extra restrictions and the ability of cabin crew to intervene in case of an incident.
Can household goods travel in international parcels or packages?
But I can put an electronic device carrying lithium batteries in my checked baggage. What’s the difference between that and an electronic device being sent by international post in a parcel?
The International Civil Aviation Organization’s Technical Instructions recommend that portable electronic devices containing lithium batteries be carried as carry-on baggage.
They also require spare lithium batteries, which do not have the added protection of the device, to be carried in the cabin.
The restrictions applied to portable electronic devices containing lithium batteries carried by passengers and crew reduce the risks they pose should they be carried in checked baggage.
What happens if dangerous goods are detected in an international parcel?
What happens if a postal parcel containing counterfeit merchandise I have ordered online is detected by customs authorities?
Relevant authorities could seize the parcel and its content and handle the package in accordance with national legislation.
Posts and customs authorities work together to detect and remove counterfeit and pirated goods being sent through the postal network.
Trafficking of illicit merchandise is a global, multi-billion dollar concern that must be stopped. Not only is it an economic crime infringing on the intellectual property rights of the companies that manufacture the goods legally, but buying counterfeit goods could be funding organized criminal groups, put consumer health and safety at risk and contribute to other ethical and environmental concerns, according to the Organization for Economic Co-operation and Development (OECD).
