Specific services provided by OIC Member States Single Windows are:
 Two Single Windows, Brunei Darussalam and Cameroon, integrate activities related to
Business registration;
 11 Single Windows offer payment services in relation to the customs duties and taxes
and/or port fees and charges56; and
 14 Single Windows offer information services, mainly with regards to Customs
regulation. The information provision service entails dynamic content on the website,
notification through RSS feeds or similar technology, and as tariff simulators.
The use of the SW services is not mandatory in all countries; only nine countries have made it
mandatory to use the SW to request permits and certificates, lodge the Customs manifest, or
submit documents to Customs57.
With regards to cross-border exchange of data
 Two OIC Member States, Togo and Cameroon, provide a service for the submission of
data for clearance purposes in third countries, namely for the Entry Summary
Declaration data to the EU Automated Import system;
 Three OIC Member States that are also ASEAN Member States form part of the pilot
ASEAN regional Single Window;
 Two OIC Member States, Senegal and Cameroon, are leading regional initiatives on the
exchange of the Certificate of Origin.
The individual coverage of the Single Windows varies significantly as can be seen from the three
examples i below.
 Three Single Windows, Burkina Faso, Kyrgyz Republic, and Tajikistan, only cover
activities related to government licenses and approvals. The Single Window also does
not support the lodgement of the Customs declarations. This constraint is mainly due to
technology limitations – a limitation that the Cameroon Single Window faces as well.
56 This may cover the entire payment process or only the e-invoicing and, probably the e-accounting steps.
57 There are different approaches to establish a mandatory service: some legal provisions state that Customs documents,
including the Customs Manifest, and related approvals will no longer be accepted in paper or pdf form (exclusively or in
addition to paper); under some legal provision requests for approval of permits are only accepted through the SW and in
electronic form.
