To ensure the availability of controlled items to the general public, each individual is allocated a quota for each product for a given period of time. When any of these controlled items are bought from any STO outlet throughout the nation, your quota is updated real-time. Controlled products and their rates can be checked from here

To check your available quota, enter your National Id card number (for Maldivians) or Passport number (for foreigners) and search. Green indicates that you have available quota while red indicates that your quota has been fully utilized for the given period.
