Last updated: 12 June 2024

The Trans-Pacific Strategic Economic Partnership (P4) entered into force in 2006. It provides for the elimination of tariffs for a majority of goods, including:

  • Electric generation equipment 
  • Mechanical equipment including pumps, appliances, and other advanced machinery
  • Electric motors, transformers, batteries, and capacitors
  • Mineral ore and processed products including graphite, manganese, copper, aluminum, and nickel
  • Various products manufactured using above minerals and metals such as sheets, powders, bars, and plates


Rules of origin established in the P4 consider goods as originating from each signatory country, and thus benefitting from preferential tariff treatment if:

  • they meet a minimum regional value content specified for each good
  • the total value of non-originating materials does not exceed 55 percent of the customs value of the final good for which originating status is claimed.
