Entering Estonia from other parts of the EU is usually a breeze – no border checkpoints and no customs – thanks to the Schengen Agreement. If arriving from outside the Schengen area, old-fashioned travel document and customs checks are required. For more information, check the Estonian Foreign Ministry’s website at www.vm.ee
When leaving Estonia, there are no limits on how much alcohol you can carry with you, though you'll have to convince border inspection agents that any large quantities are for personal consumption. When it comes to tobacco, there are heavier restrictions if you're headed to Sweden, Finland or the UK.
If arriving from outside the EU, there are the usual restrictions on what can be brought into the country; see www.emta.ee for full details, including alcohol and tobacco limits.
Not required for citizens of the EU, USA, Canada, Japan, New Zealand and Australia.
