Unnecessary Obstacles
5. Each Party shall ensure that any sanitary or phytosanitary measure that it adopts, maintains or applies is applied only to the extent necessary to achieve its appropriate level of protection, taking into account technical and economic feasibility.
Disguised Restrictions
6. No Party may adopt, maintain or apply any sanitary or phytosanitary measure with a view to, or with the effect of, creating a disguised restriction to trade between the Parties.
Article 755: International Standards and Standardizing
Organizations
1. Without reducing the level of protection of human, animal, or plant life or health, each Party shall use, as a basis for its sanitary and phytosanitary measures, relevant international standards, guidelines or recommendations with the objective, among others, of making its sanitary and phytosanitary measures equivalent or, where appropriate, identical to those of the other Parties.
2. A Party's sanitary or phytosanitary measure that conforms to a relevant international standard, guideline or recommendation shall be presumed to be consistent with Article 754. A measure that results in a level of sanitary or phytosanitary protection different from that which would be achieved by a measure based on a relevant international standard, guideline or recommendation shall not for that reason alone be presumed to be inconsistent with this Subchapter.
3. Notwithstanding paragraph 1 and in accordance with the other provisions of this Subchapter, a Party may adopt, maintain or apply a sanitary or phytosanitary measure that is more stringent than the relevant international standard, guideline or recommendation.
4. Where a Party has reason to believe that a sanitary or phytosanitary measure of another Party is adversely affecting or may adversely affect its exports and the measure is not based on a relevant international standard, guideline or recommendation, it may request, and the other Party shall provide in writing, the reasons for such measure.
5. Each Party shall, to the greatest extent practicable, participate in relevant international and North American standardizing organizations, including the Codex Alimentarius Commission, the International Office of Epizootics, the International Plant Protection Convention, and the North American Plant Protection Organization, with a view to promoting the development and periodic review of international standards, guidelines and recommendations.
