Shipping containers are one of the most reliable and cost-effective ways to move goods, whether you are relocating overseas, exporting commercial products, or looking for secure storage solutions. With their durable steel structure and ability to be transported by road, rail, or sea, containers have become an essential part of global logistics.

However, it is important to remember that not everything can be packed into a shipping container. International customs authorities and shipping companies enforce strict rules to ensure safety, legal compliance, and smooth transit. Placing prohibited or restricted cargo inside a container can lead to serious consequences such as fines, confiscation, shipment delays, or even refusal of entry at the destination port.

In this guide, we outline the main categories of items prohibited from shipping containers, explain why restrictions exist, and show how UK businesses and individuals can prepare for compliant, problem-free shipments.

Why Are Some Items Prohibited from Shipping Containers?

While containers are built for strength and versatility, they are not suitable for every type of cargo. Items are typically prohibited because they:

  • Pose a fire, explosion, or health hazard
  • Are illegal under UK or international law
  • Risk introducing pests, parasites, or diseases to a new country
  • Are perishable or likely to spoil during long journeys
  • Carry a high risk of theft or damage

Understanding these restrictions before you pack can save time, money, and stress.

Items That Cannot Be Shipped in a Container

1. Flammable and Hazardous Substances

For safety reasons, flammable, toxic, or otherwise hazardous materials are strictly prohibited from container transport. These substances pose risks to crew, vessels, and other shipments. Common examples include:

  • Batteries and fuel cells
  • Paints, solvents, bleach, and household cleaners
  • Aerosols and spray paints
  • Fireworks and explosives
  • Fertilisers, pesticides, and oils
  • Nail polish and nail polish remover

Each country has its own dangerous goods list, so always check with your shipping company or freight forwarder to ensure compliance.

2. Living Beings

It is not permissible to transport people, animals, or plants in shipping containers. Conditions inside containers are unsuitable for living beings, with limited ventilation and extreme temperatures. In addition, many countries enforce biosecurity laws to prevent the spread of invasive species and plant or animal diseases.

If you need to move pets or plants abroad, you must consult the appropriate authorities or specialist relocation services.

3. Illegal or Restricted Items

Every country enforces its own rules about what can and cannot cross its borders. Items that are illegal in the UK or abroad are strictly prohibited, including:

  • Drugs or controlled substances
  • Firearms, ammunition, and explosives
  • Certain prescription medications
  • Counterfeit goods

To avoid problems at customs, check that all items are legal in both your departure country and destination country.

4. Perishable Foods and Drinks

Standard shipping containers are not suitable for transporting perishable foods, as transit can take several weeks. Prohibited items include:

  • Fresh fruit and vegetables
  • Meat and dairy products
  • Frozen or refrigerated goods

If you need to move perishable cargo, specialist refrigerated containers (reefers) are required, which are designed to maintain precise temperature control throughout the journey.

5. High-Value or Irreplaceable Items

Although not technically prohibited, some items are too valuable or sensitive to risk in a standard shipping container. These include:

  • Jewellery, gold, or cash
  • Important documents, certificates, or passports
  • Sentimental heirlooms or antiques
  • Fine art or high-value collectables

It is usually safer to carry such items personally or use a dedicated secure courier service.

How to Ensure Your Shipment Complies

To prepare your cargo properly and avoid issues, follow these steps:

  1. Consult your shipping provider – reputable container companies in the UK can supply detailed lists of restricted or prohibited goods.
  2. Check import and export laws – each country sets its own rules, so what is legal in the UK may not be permitted abroad.
  3. Use specialist solutions when needed – hazardous, perishable, or oversized cargo may require custom-built or converted shipping containers.
  4. Get professional advice – if in doubt, ask before you pack. Compliance checks early on save time and prevent costly mistakes later.
