UK Restricted Items & Prohibited Goods to be Aware Of

As one of the UK’s leading brands in online mail management, we have years of experience dealing with the national and international delivery of parcels and goods. Using our service, we can help you to deliver and forward parcels containing a wide variety of different items. There are, however, many items that are either restricted or even prohibited entirely by the couriers that we work with within our service. This blog article will explore what these UK prohibited items are, the differences between them, and why they are restricted.

What is a Prohibited Good?

A Prohibited Good or item in terms of mail delivery is simply any item that is under no circumstances allowed to be delivered via mail. Different types of postal services worldwide, such as the Royal Mail and the US-based United Parcel Service (UPS), may have differing lists of goods that they prohibit. Prohibited goods can also be affected by the countries rules and regulations that you are trying to send mail in. For example, the UK may have a different set of rules concerning one particular good compared to the US.

What is the difference between a Prohibited Good and a Restricted Good?

Prohibited Goods and Restricted Goods have some similarities, and there may be some overlap between items in both categories; however, they are not two terms that can be used interchangeably. Unlike a prohibited item, restricted goods can sometimes be delivered, but only when specific regulations are adhered to. For example, in the UK, certain items such as types of firearms and guns are not explicitly prohibited, as with the proper licenses you are allowed to import them into the UK. Still, the movement of these goods is heavily restricted.

Why are some Items Prohibited?

The reason many items are restricted or prohibited by postal services and mail couriers is to adhere to all of the national and international regulations that govern mail. These laws are in place to ensure that the contents of post are safe for everyone handling the mail, whilst also preventing the trafficking of any illegal substances or products.

While these laws and regulations are in place to prevent the movement of certain goods, you are the one that is ultimately responsible for sticking to these rules. It is up to you to check whether or not the items you are looking to send are prohibited or restricted by the postal service you are using. As well as this, when shipping items internationally, many countries and organisations, such as the UK and the EU, will have their own restrictions. These restrictions are known as sanctions, and are used to show you what you can and cannot send to certain individuals, organisations or countries.​ ​For more information on the types of goods that have restrictions on them, you can read on for a comprehensive list of the types of goods you may expect to see prohibited or restricted.

The UK’s Common Prohibited & Restricted Items

When it comes to what you can safely ship under the UK’s laws and regulations, you will find that it is a mixture of products ranging from the obviously dangerous to commonplace items you might find in your home. For this reason, it can be easy to be caught out regarding what is acceptable for shipping and what isn’t.

Restricted Goods

The following lists of substances and materials includes any items that may be sent by some postal services and couriers with the appropriate restrictions. In all instances, the sender’s name and return address must be clearly visible on the outer packaging.

Aerosols for toiletry or medicinal purposes

This category of goods includes any aerosol products that are designed for either medicinal or toiletry use. Items such as the following would fall under this category:

  • Deodorants and body sprays
  • Hair Sprays
  • Hair Removal & Shaving Creams
  • Medicinal Aerosols for prevention and cure; such as flea sprays

These goods can sometimes be shipped so long as the correct packaging guidelines are adhered to. You should ensure that the valves of the aerosols are appropriately sealed to prevent the contents from releasing unexpectedly. Restrictions on the number of aerosol products are to be expected too, such as no more than two aerosol items per parcel and the maximum volume of the item (for the Royal Mail, aerosols must not contain more than 500ml of liquid).

Alcohol: 24% to 70% ABV (Alcohol by Volume)

This category encompasses alcoholic beverages containing these metrics of ABV (this should be displayed somewhere on the packaging). Includes drinks such as:

  • Gin
  • Rum
  • Vodka
  • Whisky

Beverages like this can be shipped, providing the correct guidelines are met for the service you are using. They should be wrapped in polythene, sealed with tape, and surrounded by an absorbent material for added protection. Maximum volumes and number of items per parcel must be met, and as with any fragile materials such as glass, the parcel should be marked clearly as “FRAGILE”. 

Alcohol: Under 24% ABV (Alcohol by Volume)

This category, similar to the previous one, includes alcoholic beverages with less than 24% ABV. This includes drinks such as:

  • Beer
  • Wine
  • Champagne

The same packaging guidelines must be met with these beverages as with the previous category, pertaining to maximum volumes and amounts, and making sure that the glass bottles are appropriately secured and marked as fragile.

Batteries (Alkaline, Nickel, Zinc) 

This category covers the following types of batteries:

  • New alkaline metal,
  • Nickel metal hydride (NiMH)

This category covers the following types of batteries:

  • Sealed Lead Acid Batteries

Electronic Devices sent with Lithium Batteries

This category covers any of the following products, wherein the battery is not sent connected to the device. This includes items such as mobile phones and digital cameras. The devices the batteries come with must be packaged so as to prevent accidental activation. 

The maximum number of lithium batteries allowed in each parcel is the minimum number required to power the device plus two spares while adhering to maximum size restrictions. The batteries must also not be defective or faulty in any way, insulated and protected from short-circuiting. 

Electronic devices connected to Lithium Batteries

This category covers any of the following products, wherein the battery is sent connected to the device. Like the previous category discussed, this includes items such as mobile phones and digital cameras that must be packaged in a way that avoids the risk of accidental activation. 

Each parcel must contain no more than four cells or two batteries installed in the device, and faulty or defective batteries are forbidden.

Environmentally Hazardous Substances

Samples of any environmentally hazardous substances must not exceed the maximum amounts of your courier of choice. For the Royal Mail, for example, this is 5 litres or 5 kgs. The substances must be packaged in a leak-proof container, protected by a cushioning material within a rigid outer packaging.

Guns For Sporting Use

Any guns for sporting use refer to guns that fall under Section 1 and Section 2 firearms. Examples of such firearms include the likes of air-powered weapons and their component parts. These weapons must be sent in compliance with UK law, as well as subject to any regulations regarding the possession of firearms.

Human or Animal Ashes

Ashes of humans and animals may or not be prohibited depending on the postal service you use. The Royal Mail is an example of a service that accepts these substances with restrictions applied. In this instance, they must not exceed a volume of 50g, and need to be securely packaged in sift-proof containers with strong external packaging.

Human or Animal Samples

As with ashes, these items may or not be prohibited depending on the chosen service and are also allowed with restrictions via the Royal Mail. These substances may only be sent by or at the request of qualified medical & dental practitioners or by other recognised laboratories and institutions.

Under the Royal Mails regulations, the total sample size must not exceed 1kg, and only solids may be sent. All samples must comply with Packing Instruction 650 regulations.

This category only covers liquids that are not classified as being dangerous goods. These substances must be securely packaged in leak-proof internal and external containers, with the appropriate maximum restrictions depending on your courier of choice. Any substances kept in glass bottles must be clearly marked as “FRAGILE”. 

Liquids under 1 Litre

As with the previous category, only liquids that are not classified as being dangerous are covered here. These substances must be packaged in secure, leak-proof internal and external containers, with the appropriate maximum restrictions depending on your postal service of choice. All substances kept in glass bottles must be marked as “FRAGILE”.

The packages containing the creatures must be clearly marked with the following message, “URGENT - LIVING CREATURES - HANDLE WITH CARE”. They must be packaged securely in a way that protects the animals and the couriers from harm, with 1st Class used as the minimum service.

Nail Varnish, Polish or Gel

The packaging guidelines for these types of products may differ slightly depending on the service used, but for the Royal Mail, the volume per item must not exceed 30ml, and no more than four items must be packaged in any one parcel. Packages must be firmly cushioned to prevent any breakages and spillages.

Perfumes and Aftershaves

Similarly to the previous category, the regulations may differ depending on the service used, but for the Royal Mail, the volume per item must not exceed 150ml, and no more than four items must be packaged in any one parcel. Again, packages must be strongly cushioned to prevent any breakages and spillages, and they need to be sent in their original retail packaging.


Perishable items such as flowers and foodstuffs, frozen and chilled, are eligible for postage provided that the appropriate packaging regulations are adhered to. 1st class postage must be used as the minimum service, and the perishables should be able to withstand a journey of up to 48 hours in the UK. These products must be suitably sealed to prevent any leakages or the tainting of other items. These parcels must also be clearly labelled as “PERISHABLE” on the external packaging.
