Dangerous goods
What can be included and what cannot?

Many everyday objects are deemed dangerous for the purposes of shipping. This also applies to seemingly harmless things such as perfume, mobile phones and alcohol.

What are regarded as dangerous goods?

Dangerous goods are defined as goods that present a danger to the safety of people, infrastructure or the environment during transport. These also include everyday products such as perfume, mobile phones and alcohol among others. These seemingly harmless items have potentially dangerous characteristics. For example, they could be explosive, flammable, poisonous or corrosive.

In international postal traffic, the legal guidelines of the International Civil Aviation Organization (ICAO; Dangerous Goods Regulation and Annex 18) and the Swiss Air Transport Ordinance (LtV Art. 16) apply.

According to these requirements, Swiss Post is prohibited from transporting dangerous goods by airmail apart from in a few exceptional cases.

We only transport goods, which comply with the legal guidelines. 

As a sender, you are responsible for complying with these guidelines and for providing a clear, unambiguous and truthful declaration of the contents of your goods.

By signing the waybill, you confirm

...that you comply with these guidelines and acknowledge that your consignment can be opened as part of security checks.

…that you acknowledge that you may be held liable for the false declaration of goods and any damages, and that this may result in criminal prosecution.

What is prohibited?

We are not entitled to transport these 9 categories of prohibited dangerous goods internationally for legal, health or safety reasons. The list is not exhaustive.

If you are not sure whether or not a certain item is fit for transport, please contact Customer Service on 0800 888 100.

Lithium metal batteries must not contain more than 1 g lithium per cell and 2 g lithium per battery. Loose or damaged lithium batteries are not permitted. It is the customer’s responsibility to ask the manufacturer or retailer about battery type and performance before shipping.
