Can I import toys guns like bb guns or airsoft guns to Mauritius?

They are prohibited in Mauritius according to The Firearms Act 2006.

To import a firearm, you will need an Import Permit.

To get the Import Permit, you will need a Firearm Licence.

To get a Firearm Licence, you will need a Competency Certificate and will have to undergo training for this.

Maybe these will be your answer -->
