What items are prohibited or restricted from sending ?
For safety reasons and to comply with national and international regulations, there are both restricted and prohibited items that are excluded from the postal and courier network.
If you are shipping goods, it is your responsibility to ensure that you are not posting or shipping any restricted or prohibited items. It is essential to make sure that you know what is and what isn’t allowed to be shipped, otherwise you could find that you are prosecuted for shipping prohibited goods.
