Overview

Electronics is Vietnam's single largest export category by value, overtaking garments and footwear in the early 2010s and holding that position since. The industry is overwhelmingly foreign-invested: multinational firms own or contract the factories, import most components, assemble finished goods, and re-export them. The domestic private sector participates mainly as a supplier of packaging, simple parts and ancillary services, though that picture is slowly changing.

The sector divides broadly into two product families: consumer electronics (dominated by smartphones and tablets) and components (printed circuit boards, camera modules, semiconductors, and connectors). Both are present in Vietnam, but smartphones generate the largest share of export turnover by a considerable margin.

Anchor investors and the northern corridor

Samsung is the single most consequential investor. Its Vietnamese operations, which began with a handset factory in Bac Ninh province in 2009, expanded to a second large complex in Thai Nguyen province and subsequently to display and consumer-electronics plants near Ho Chi Minh City in the south. At their peak, Samsung's Vietnamese factories accounted for roughly half of the company's global smartphone output, making the plants among the largest anywhere in the world by volume. The figure is contested and shifts with production decisions, so current share should be verified against Samsung's annual disclosures.

Hai Phong hosts LG Electronics' former display plant (LG exited in 2021, selling to a consortium) and has attracted a cluster of component suppliers. Intel operates an assembly and test facility for processors in Ho Chi Minh City, one of the company's largest such sites globally. Foxconn, Luxshare and Goertek — all key in the Apple supply chain — have expanded capacity across northern provinces including Bac Giang and Bac Ninh.

The geographical logic of the northern corridor is proximity to the Chinese border crossings at Lang Son and Mong Cai, access to Hai Phong port, and relatively lower land and labour costs compared with the urban south.

Export share and trade data

Vietnam's General Statistics Office and the Ministry of Industry and Trade publish annual electronics export figures, typically broken down into phones and parts, computers and parts, and other electronics. Phones and parts alone have in recent years represented the largest single line item in Vietnam's total merchandise exports, often accounting for roughly one fifth of all export turnover — though the precise share fluctuates with global demand cycles and should be taken from the most recent GSO release.

The trade structure is unusual: Vietnam simultaneously imports large quantities of electronic components (principally from South Korea, Japan, China and Taiwan) and exports finished or semi-finished electronics. The gap between import value and export value — the processing margin — reflects the limited domestic value added. This processing-trade character is a recurring point in economic assessments of the sector's contribution to GDP versus its contribution to gross export figures.

Supply chain diversification from China

From around 2018 onward, and accelerating after 2020, several forces pushed electronics firms to diversify assembly outside China: rising Chinese labour costs, the United States–China trade dispute and associated tariff schedules, Covid-era supply disruptions, and customer pressure to reduce single-country concentration. Vietnam was the primary beneficiary in Southeast Asia, partly because of existing Samsung infrastructure, partly because of its trade agreements.

Vietnam has signed a large number of free trade agreements, including the EU–Vietnam Free Trade Agreement (EVFTA, in force August 2020) and the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP). These reduce or eliminate tariffs on electronics exports to major markets, subject to rules-of-origin requirements. Meeting those rules of origin — which generally require a defined share of value to be added within Vietnam or the agreement area — is itself a driver of pressure to deepen the local supply chain rather than merely assemble imported kits.

China remains both a competitor and a critical upstream supplier. The degree to which Vietnam has genuinely substituted for Chinese production, versus re-routing Chinese-origin goods through Vietnamese assembly, is a matter of ongoing scrutiny by trading partners including the United States.

Value capture: assembly versus design

The central structural question about Vietnamese electronics is how much economic value the country retains. Assembly operations — mounting components onto boards, fitting screens, testing and boxing — are labour-intensive and generate employment but carry thin margins. The higher-margin activities in electronics — chip design, software, intellectual property licensing, brand ownership — remain concentrated in South Korea, the United States, Japan and Taiwan.

Economists and Vietnamese government planners have discussed this gap for over a decade under the rubric of moving up the value chain (nâng cao giá trị gia tăng). Concrete progress is measured by the domestic content ratio: the share of a finished product's value that originates in Vietnam. For smartphones, this figure has been estimated at well under 10% by several researchers, though methodologies differ and the number is not officially published in a consistent series.

FPT Software and a small number of Vietnamese technology firms do perform software development and some hardware design, but they serve different market segments from the mass-assembly factories. A domestic semiconductor design capability remains nascent; Vietnam has no volume chip fabrication facility. Government policy documents, including the national digital transformation programme, identify semiconductors as a priority sector for the 2020s, though translating stated priority into funded industrial capacity is a separate and slower process.

Provincial administration and investment zones

Following Vietnam's administrative reorganisation on 1 July 2025, the country operates a two-tier system of provinces and communes, with the former district tier abolished. The industrial parks that host electronics factories are administered at province level. Bac Ninh and Thai Nguyen — key electronics provinces — have both retained their identities under the reorganisation, as has Hai Phong. Bac Giang, which saw rapid growth in Apple-supply-chain investment from 2020, likewise remains a distinct province.

Foreign investors enter through industrial parks (khu công nghiệp) or economic zones (khu kinh tế), which offer standardised land lease arrangements, utilities and customs procedures. The legal framework for investment incentives — including corporate income tax preferences for high-tech manufacturers — is set nationally but administered provincially. Vietnam's adoption of the global minimum corporate tax (the OECD Pillar Two 15% floor, which Vietnam legislated from 2024) has altered the incentive calculus for large multinationals and is an active area of policy adjustment.

Risks and outlook

The sector faces several structural and cyclical risks. Dependence on a small number of anchor firms — Samsung above all — means that a production decision in Seoul has outsized effects on Vietnamese export figures, employment and provincial tax revenue. Global smartphone market saturation and the lengthening of device replacement cycles create demand-side uncertainty.

Geopolitical risk runs in two directions: the same trade tensions that drove diversification into Vietnam could, under different political conditions, redirect investment again. The United States market in particular subjects Vietnamese electronics exports to periodic scrutiny regarding rules of origin and potential tariff exposure.

On the supply side, Vietnam competes with India, Indonesia and Mexico for new investment mandates. India's production-linked incentive scheme for electronics has attracted commitments from several firms that were also considering Vietnamese expansion. Labour costs in Vietnam's industrial zones have risen steadily, narrowing but not eliminating the gap with coastal China.

The longer-term question — whether Vietnam can develop the engineering talent base, capital markets and institutional framework to support design-intensive electronics rather than assembly-intensive electronics — is unresolved and will not be answered quickly.
