The CRO considers the input of the TCRO with the aim of endorsing the TCRO's interpretations and opinions, and, if necessary, refining or elaborating on the work of the TCRO and/or developing new approaches.Upon completion of all the work in the TCRO, the CRO is to consider the results in terms of their overall coherence (Article 9:3).
When doing this, the Ministerial Conference is also to give consideration to arrangements for the settlement of disputes relating to customs classification and to establish a time-frame for the entry into force of the new annex. until the entry into force of the new harmonized rules) Members are required to ensure that: (a) rules of origin, including the specifications related to the substantial transformation test, are clearly defined; (b) rules of origin are not used as a trade policy instrument; (c) rules of origin do not themselves create restrictive, distorting or disruptive effects on international trade and do not require the fulfilment of conditions not related to manufacturing or processing of the product in question; (d) rules of origin applied to trade are not more stringent than those applied to determine whether a good is domestic, and do not discriminate between Members (the GATT MFN principle).

WCO Technical Committee A Technical Committee on Rules of Origin is created under the auspices of the World Customs Organization (formerly the Customs Cooperation Council).
Not much more work was done on rules of origin until well into the Uruguay Round negotiations.
In the late 1980s developments in three important areas served to focus more attention on the problems posed by rules of origin: Increased number of preferential trading arrangements First, an increased use of preferential trading arrangements, including regional arrangements, with their various rules of origin; Increase in the number of origin disputes Second, an increased number of origin disputes growing out of quota arrangements such as the Multifibre Arrangement and the voluntary steel export restraints; and Increased use of anti-dumping laws Lastly, an increased use of anti-dumping laws, and subsequent claims of circumvention of anti-dumping duties through the use of third country facilities.
The draftsmen of the General Agreement stated that the rules of origin should be left: ...within the province of each importing country to determine, in accordance with the provisions of its law, for the purpose of applying the most-favoured-nation provisions (and for other GATT purposes), whether goods do in fact originate in a particular country.
