What are customs rules?

Customs Rules are regulations imposed on a passenger's goods when they're travelling across international borders.

Custom rules may differ between countries. Therefore, it's essential to research the rules of your departure and arrival destinations.

Customs rules exist to:

  • Prevent the spread of diseases.
  • Prevent drug trafficking.
  • Prevent dangerous goods from getting into a country.
  • Prevent harm to the environment.
  • Monitor goods being brought into a country.


You will usually pass through Customs after collecting your baggage, but before entering the public arrivals area.

How does customs work?

Once you've collected your luggage, you'll proceed through customs.

This is a quick and easy process, especially if all the items you've brought are allowed into the country. However, if you have specific items that aren't usually permitted or require special documents to be allowed in, then you'll have to declare them. This can apply to items like meat and alcohol.

Sometimes, you may need to pay a tax to bring declared items into a country.

Customs FAQs

Do you go through customs before or after your flight?

As a general rule, you will go through customs upon arrival at your international destination, so after your flight.

Do connecting flights go through customs?

This depends. If you're connecting between international flights, then you won't usually need to clear customs. However, if you're connecting between domestic destinations, you must clear customs.

What do you declare at customs?

This depends on the country you're flying to, as different countries have differing rules on what is and isn't prohibited.

Some items that often surprise travellers and frequently require declaration are monetary instruments, such as traveller's cheques, banknotes, gold coins, promissory notes, money orders, negotiable cheques, and securities or stocks.

What happens if you don't declare customs?

If you don't declare prohibited goods at customs or provide false information, you risk facing legal consequences. Depending on the country, your goods and any vehicle used to transport them may be seized or fined, and the item(s) will be confiscated. In extreme cases, you may be liable to prison time.
