What you can't send in the post
Some items are dangerous in transit and are banned or restricted. Sending them can lead to your parcel being destroyed, compensation being refused or, in serious cases, prosecution. Rules differ between carriers and between UK and international post, so always check with the carrier you're using.
This is a general guide only. Each carrier publishes its own prohibited and restricted items list – check it before you send anything you're unsure about.
Never allowed
- Explosives, fireworks and ammunition
- Flammable gases and liquids, such as lighter fuel and petrol
- Corrosives, such as bleach, acids and drain cleaner
- Illegal drugs and offensive weapons
- Counterfeit goods
Restricted (allowed only with conditions)
- Aerosols (deodorant, hairspray): Royal Mail accepts limited quantities within the UK only, sent by surface mail – not abroad.
- Perfume and aftershave: limited quantities within the UK only; most international services won't accept them.
- Nail varnish: as with perfume – small quantities, UK only.
- Lithium batteries: generally only accepted when fitted inside the device they power, and within quantity limits. Loose and damaged batteries are not accepted.
- Alcohol: limits apply, and it can't be sent abroad with most standard services.
- Medicines: some can be sent within the UK if properly packed; many countries restrict imports.
- Food: non-perishable food is fine in the UK, but many countries restrict or ban food imports.
Cash and valuables
Never send cash by ordinary post. If you must, Royal Mail Special Delivery offers limited cover for money and jewellery – check the current limits. A bank transfer is safer.
Sending abroad
International post travels by air and is subject to aviation rules, so restrictions are stricter. Many everyday items – perfume, aerosols, nail polish, e-cigarette liquids – can't go abroad by standard post at all. Destination countries also have their own bans, especially on food, plants, seeds and medicines.
If in doubt
Ask at the Post Office counter, or check the carrier's list online before booking. Declaring contents honestly protects you: if a prohibited item is found, any compensation claim will usually be refused.
