Prohibited and restricted items - advice for business customers


A guide to what our business customers can and cannot send in the mail

If you're not a business customer, please visit royalmail.com/prohibitedgoods for information on what you can and cannot send in the mail.

Sending items from Great Britain to Northern Ireland 

Under Government guidance, customers are not required to make any changes to the way they send mail via Royal Mail from Great Britain (England, Scotland and Wales) to Northern Ireland from 1 January 2021. There are two exceptions to this that will impact some business customers only. According to the Government guidance:   

  • If you are a Northern Ireland based business receiving goods valued at £135 or more you will need to make a declaration. Businesses will be able to use the Government’s free Trader Support Service to do so. 
  • There are new requirements on businesses sending the prohibited and restricted goods listed in the guidance.

Until any further changes are announced, Royal Mail will continue to collect and deliver items from Great Britain to Northern Ireland as usual.

Are you posting safely?

To comply with national and international regulations governing the carriage of mail, and ensure that mail in transport does not present a danger to the general public, we restrict or prohibit certain items from our network.

Prohibited items must never be sent in the post.

Restricted items may be sent in the post, but restrictions will apply. Items can be restricted due to packaging, volume, quantity, labelling or the product that can be used. These conditions must be met when posting both within the UK and Internationally.

We want to ensure the mail is safe for everyone. Many everyday items, such as aerosols, nail varnish and perfumes are considered dangerous goods under transport legislation.

If you're posting items overseas other postal administrations may have different prohibitions, see our Country Guides. When using our International Business Tracked Priority service, additional prohibitions and restrictions will apply alongside those listed on this page. Please see here for further information.

In addition, a number of countries and international organisations, including the United Kingdom and the European Union, impose certain restrictions, also known as sanctions, on what you can send to certain individuals, organisations or countries.

It is your responsibility to check the list of prohibited and restricted items and any applicable packaging, volume, quantity, labelling and product restrictions that apply prior to posting any item. In order to comply with aviation security regulations, items destined for air transport will go through certain aviation security controls. There may be instances where we are unable to clear certain items and these will be returned to the sender where it is safe to do so. Please note consequential loss cover is not available when posting any restricted items.

The comprehensive A-Z list below gives you detailed information about the things you cannot post with us, or where restrictions are in place and covers all our UK mail and International mail services. This list of prohibited and restricted items reflects our general terms and conditions.

If you are not sure about the item you wish to post please contact us using the link at the bottom of this page.

Items classified as dangerous goods - Unless specifically permitted (as shown in the A-Z list) dangerous goods are forbidden in mail.
