The ITA is solely a tariff cutting mechanism. While the Declaration provides for the review of non-tariff barriers (NTBs), there are no binding commitments concerning NTBs. There are three basic principles that one must abide by to become an ITA participant: 1) all products listed in the Declaration must be covered, 2) all must be reduced to a zero tariff level, and 3) all other duties and charges (ODCs) must be bound at zero. There are no exceptions to product coverage, however for sensitive items, it is possible to have an extended implementation period. The commitments undertaken under the ITA in the WTO are on an MFN basis, and therefore benefits accrue to all other WTO Members.
