ASEAN NTM Database. The ASEAN NTM Database is a compilation of notifications submitted by the member states and will form part of the ASEAN Trade Repository. The notification is a list of NTMs each member state imposes on its imports according to HS Code and NTM type. First, the notification details vary significantly among the member countries. In some cases, the notification provides the relevant national legislation or regulations for the NTMs and the ministry/ department in charge of the implementation. Most, however, do not provide the purpose of the NTMs or the manner of their implementation; or if they do, these are not clear and precise. The information is crucial in determining whether the NTMs are justifiable and necessary and, hence, should be permitted.
