CPTPP provides three methods to determine the origin of a good, including:

1. Wholly obtain
2. goods manufactured from raw materials in the CPTPP areas,
3. Product-Specific Rules of Origin (PSR)

Besides, the provision on accumulation regulates that Each Party shall provide that an originating good or material of one or more of the Parties that is used in the production of another good in the territory of another Party is considered as originating in the territory of the other Party.

Origin procedures

To facilitate trade, reduce transaction time and import and export cost, CPTPP allows exporters, producers and importers to certify origin themselves. This is a new provision which is not regulated in other FTAs signed by Viet Nam.

For Viet Nam, certification of origin by the importers has not been applied widely so Viet Nam can have a transitional period to help Vietnamese state agencies and enterprises get used to such methods. Some regulations on the transitional period are as follows:

• For imported goods: Viet Nam reserves the right to apply certification of origin by the importers after 5 years of entering into force.
• For exported goods: There are two methods which are applied flexibly: (a) certification of origin issued by a competent authority; and (b) certification of origin issued by an approved exporters within a maximum of 10 years. After 10 years, Viet Nam will apply only self certification of origin.
