Rules of origin determine preferential tariff eligibility under India-Mauritius CECPA; proof, verification and penalties govern claims. These Rules define origin criteria for preferential tariff treatment under the India-Mauritius CECPA: a product is originating if wholly obtained in a Party or if it satisfies Product Specific Rules (CTC, value addition tests, or other PSR conditions) with final manufacture in the exporting Party. They set de minimis provisions, list minimal operations that do not confer origin, permit bilateral cumulation, and regulate proof of origin (approved exporter self certification or Certificates of Origin), documentation retention, verification procedures including on site visits, and measures for denial, suspension and penalties under national laws.
