If you are leaving Mauritius for Rodrigues you are not entitled to duty free facilities.
For some destinations, restrictions apply on the sale of LAGs. Duty-free liquids, aerosols and gels may be confiscated if you pass through pre-board security screening at a connecting airport in another country.
Check with your airline or the airport duty free shop before purchase of such items.
Items purchased at duty-free shops should be packed in a Security Tamper Evident Bag (STEB) for transit flights. Do not open such bag(s) before you clear security screening through all connecting airports.
