What you can't bring through customs

By the Viamo editorial team · Editor Terje Moy · Last updated July 2026 · 5 min read

Customs rules trip up honest travellers far more often than smugglers — a homemade salami for a relative, cash saved for a big purchase, or one too many bottles bought duty-free. The details vary by country, but the same handful of categories cause almost all the problems: food and animal products, cash above a threshold, counterfeit goods, and duty-free allowances.

Food and animal products

Bringing meat, dairy, and many other animal or plant products across an international border is restricted or banned in most countries, for biosecurity reasons rather than taxation — a rule designed to stop diseases like African swine fever or foot-and-mouth disease crossing borders in someone's suitcase, not to catch out tourists. The EU, for instance, generally bans bringing meat and dairy products in personal luggage from outside the EU, with narrow exceptions for certain amounts of powdered infant milk, special dietary or medical foods, and travel from a handful of countries with recognised equivalent standards.

• Homemade or market-bought meat, cheese and dairy products from outside the destination's customs area are the single most common item confiscated at borders — travellers frequently don't realise a gift of local ham or cheese for family isn't allowed through.
• Fresh fruit, vegetables, seeds, plants and untreated wood products are commonly restricted too, again for biosecurity rather than tax reasons.
• Rules differ sharply by direction of travel — what you can bring into the EU from a non-EU country is different from what you can carry between two EU countries, which usually has no restriction at all since it's a single customs area.

Declaring cash

Carrying cash isn't illegal, but most countries require you to declare amounts above a set threshold when crossing an international border, whether entering or leaving. Within the EU, for example, travellers carrying €10,000 or more (or the equivalent in another currency, or combined with things like traveller's cheques) must declare it when crossing the EU's external border. Similar thresholds — commonly somewhere in the region of $10,000 or the local equivalent — apply in the US, UK and many other countries, though the exact figure and what counts towards it varies.

• The threshold usually applies per person, and to the combined value of cash, cheques and some other financial instruments, not just banknotes.
• Failing to declare cash above the threshold — even if the money is entirely legitimate — can result in it being seized, sometimes for a lengthy investigation, plus a fine.
• Declaration is normally a simple form at the customs desk or a red-channel conversation, not a barrier to carrying the money at all — it exists for anti-money-laundering purposes, not to stop legitimate travel.

Counterfeit and restricted goods

Counterfeit branded goods — fake designer bags, watches, trainers and similar — are prohibited from import in most countries, and this is enforced more actively than many travellers expect, particularly returning from destinations known for counterfeit markets. Beyond counterfeits, common categories of restricted or banned goods include:

• Protected wildlife products, such as ivory, certain furs, coral, and items made from endangered species, which fall under international CITES rules regardless of how innocently they were bought.
• Weapons, including some items that aren't obviously weapons in their country of origin, such as certain knives or replica firearms.
• Some medications that are legal at home but controlled or banned at your destination — worth checking specifically if you're travelling with prescription medicine, particularly anything containing controlled substances.
• Cultural artefacts and antiquities, which a number of countries restrict from export regardless of how they were acquired.

Duty-free allowances

Duty-free shopping lets you buy alcohol, tobacco and other goods without the destination country's usual taxes applied at the point of sale — but that doesn't mean unlimited quantities can be brought in tax-free at the other end. Every country sets its own personal allowance for what you can bring in without declaring it and paying duty, typically covering:

• A set volume of alcohol, often split between spirits and wine/beer with different limits for each.
• A set quantity of tobacco products.
• A total value limit for other goods (electronics, perfume, souvenirs and so on) bought abroad.

Exceeding the allowance doesn't mean the goods are banned — it usually just means declaring the excess and paying the applicable duty and tax, though not declaring it when required can mean a fine on top. Allowances also differ depending on whether you're arriving from within a shared customs area (such as EU country to EU country, where there is generally no allowance limit for personal use) or from outside it.

What actually happens at the border

Most countries use a green/red (or green/amber/red) channel system: green for nothing to declare, red for something to declare. Walking through green with undeclared restricted or over-allowance goods, if caught, is generally treated more seriously than an honest declaration in red would have been — the penalty is often for the non-declaration as much as for the item itself. If you're not sure whether something needs declaring, using the red channel or asking an officer costs you a few minutes; guessing wrong in the green channel can cost considerably more.

Frequently asked questions

Can I bring cheese or cured meat home as a gift?

Often not, if you're crossing into a different customs area — many countries, including the EU as a bloc from outside its borders, restrict meat and dairy products in personal luggage for biosecurity reasons. Check the specific rule for your route rather than assuming a small amount is fine.

How much cash can I carry without declaring it?

It depends on the country, but a common threshold is around €10,000 or the equivalent, required when crossing an international border. Amounts above that generally must be declared, even though carrying cash itself is legal.

What happens if I exceed my duty-free allowance?

Usually you simply declare the excess and pay duty and tax on it. The problem arises mainly when travellers don't declare it and are found with goods over the limit in the "nothing to declare" channel.

Are customs rules the same for every border I cross?

No — rules differ by country and, importantly, by whether you're moving within a shared customs area (like the EU) or across its external border. Always check the specific rule for your route rather than assuming it matches a previous trip.
