Tariff elimination and regulatory alignment with key trading partners are essential to the global competitiveness of U.S. chemical manufacturers. U.S. free trade agreements, in particular the North American Free Trade Agreement (NAFTA), are the foundation of the multilateral trading system as embodied by the World Trade Organization (WTO). U.S.-written rules, and the U.S. strategy of competitive liberalization, compel trading partners to include higher standards in their own trade agreements. As a result, they become better partners and advocates at the WTO.
