IMF Data Dissemination Standards GDDS/SDDS on Merchandise Trade
The IMF's data dissemination standards consist of two tiers: the General Data Dissemination System (GDDS), which would apply to all Fund members, and the more advanced Special Data Dissemination Standard (SDDS), for those member countries having or seeking access to international capital markets.
In general, a country subscribes to either GDDS or SDDS.
GDDS provides information on Trade Data Characteristics, Quality, Plans for Information, Dissemination Formats as well as Contact Persons (Not available).
SDDS provides information on Trade Data Coverage, Periodicity, and Timeliness, Access by the Public, Integrity, Quality as well as Contact Persons. http://dsbb.imf.org/Applications/web/sddscountrycategorylist/?strcode=LUX
