Vietnam Sourcing Guide: Finding Suppliers, RCEP Rules of Origin, Payment and Documents

Quick Answer

Vietnam is a common choice for companies pursuing supply chain diversification (China plus one) and is a member of the Regional Comprehensive Economic Partnership (RCEP): RCEP entered into force on 1 January 2022 for 10 countries including Vietnam, Thailand, Japan, China and Australia, and for South Korea on 1 February 2022. Keys to sourcing from Vietnam: (1) verify factories on site or through a third party, (2) put specifications and samples in writing, (3) confirm origin and destination duties, (4) spell out payment and document terms. Note that Taiwan is not an RCEP member, so Vietnamese goods exported to Taiwan don’t get RCEP preferences; but goods exported directly from Vietnam to RCEP members can be assessed against RCEP rules of origin.

Why Do Companies Consider Vietnam?

According to English Wikipedia’s “China plus one” article, companies adopt the strategy because of rising operating costs, risk diversification and access to new markets, with common alternatives including India, Vietnam, Thailand, Indonesia, Malaysia and the Philippines. Vietnam has therefore become one of the production locations many brands and buyers evaluate.

What RCEP Means for Vietnam Sourcing

SituationDoes RCEP apply?
Vietnamese goods exported to RCEP members such as Japan or AustraliaCheck RCEP rules of origin to claim preferential duties
Vietnamese goods exported to TaiwanNo; Taiwan is not an RCEP member
Transshipped via Taiwan and re-exportedTransshipment doesn’t change origin; direct consignment rules also apply

ASEAN explains that RCEP’s rules of origin and regional cumulation let businesses use regional supply chains more flexibly. This is a common multilateral trade plan: lawfully shipping directly from Vietnamese factories to RCEP markets. See What Is Multilateral Trade? and What Are Rules of Origin?
