Vietnam Manufacturing Investment: The Legal Questions Every Investor Asks
Vietnam is one of the most active manufacturing destinations in Southeast Asia, attracting investment from Germany, Japan, South Korea, the United States, China, Turkey, Mexico, and across the G20. Across all investor nationalities, the legal questions about Vietnam factory setup are remarkably consistent — because the regulatory framework applies equally regardless of where the investor comes from.
The following FAQ draws on the questions most commonly asked by international manufacturers considering or executing Vietnam factory investment, answered by Attorney Vu Manh Quynh of ECOVIS Vietnam Law.
Licensing: IRC, ERC and Business Scope
What approvals are required to legally manufacture in Vietnam?
A standard manufacturing foreign-invested enterprise requires: an Investment Registration Certificate (IRC) approving the project’s scope, location, capital, and investor; an Enterprise Registration Certificate (ERC) incorporating the legal entity; tax registration; environmental compliance confirmation; fire safety acceptance; and, depending on the product, sector-specific permits from MOIT or other line ministries. The IRC and ERC are sequential — IRC is issued first, ERC follows. Operating before all required approvals are in place exposes the company to administrative sanction and potential production suspension.
What is the practical risk of a vague IRC investment scope?
An IRC with a vaguely defined product scope — for example, “manufacturing of mechanical parts” without specifying product categories, HS codes, or end-use sectors — creates operational risk in three ways. First, customs classification disputes arise when imported machinery or raw materials do not clearly fall within the approved scope. Second, domestic sales or service activities beyond the strict scope of the IRC may be treated as unlicensed trading or service provision. Third, future product expansion or model changes may require IRC amendment, delaying new production lines.
German and Japanese investors, accustomed to precise project definitions, typically ask for specificity at the IRC drafting stage. This is correct practice: a well-drafted IRC scope that specifically names product categories, production processes, and permitted sales channels prevents amendment costs later.
Can a foreign investor expand an existing Vietnam manufacturing project?
Yes, but expansion requires IRC amendment — it does not happen automatically. An expansion that increases investment capital, changes the production scope, adds product lines, extends the factory footprint, or increases environmental emissions must be registered through the applicable authority (DPI or IPC management board). The amendment process typically takes four to eight weeks depending on whether it triggers environmental re-assessment or additional sector approvals. Companies that expand production without amending the IRC operate outside their licensed scope — which creates customs, tax incentive, and enforcement exposure.
Industrial Park and Site Selection
What should investors check before signing a factory lease in an industrial park?
Eight items require legal verification before signing: the park developer’s land use right certificate and sublease authority; zoning classification and permitted industries for the specific plot; infrastructure completion status (power connection, water, wastewater treatment); fire safety and environmental certification of the park infrastructure; the IRC processing timeline and track record of the applicable DPI or IPC management board; expansion rights and available adjacent plots; logistics infrastructure and proximity to customs; and the lease terms including renewal rights, handback conditions, and force majeure provisions.
Investors who sign industrial park leases based on marketing materials without legal due diligence on these eight points frequently discover that the park’s infrastructure is incomplete, the environmental conditions are more restrictive than indicated, or the IPC management board’s processing timeline for IRC applications is significantly longer than estimated.
What should investors check before leasing a ready-built factory?
Ready-built factories offer speed but require specific due diligence. The key checks are: construction completion certificate (the building must be legally completed, not just physically finished); fire safety acceptance certificate for the structure; permitted use classification (the approved use must match the investor’s production type and environmental classification); floor loading capacity and ceiling height for the intended machinery; utility supply specifications (voltage, water pressure, wastewater connection capacity); and the landlord’s rights to sublease to a foreign-invested enterprise. Japanese manufacturers, who frequently use ready-built factories for precision electronics and component assembly, are particularly sensitive to cleanroom compatibility and environmental suitability — factors that require physical inspection and engineering assessment beyond legal due diligence.
How should investors compare Vietnam provinces for factory location?
Province comparison for manufacturing investment should cover five legal and regulatory dimensions: IRC processing speed at the DPI or IPC management board (varies from fifteen to forty-five working days across provinces); labour supply depth and prevailing wage levels for the target skill category; industrial zone infrastructure quality and environmental permit track record; provincial CIT incentive rates and zone classifications; and logistics infrastructure including port access, road quality, and customs office proximity. Provinces with well-established industrial zones — Binh Duong, Dong Nai, Long An, Bac Ninh, Hai Phong — typically offer faster processing and more experienced industrial infrastructure. Newer provinces may offer lower land lease rates but slower regulatory processing.
Environmental and Construction Compliance
When does a manufacturing project require environmental pre-approval?
Vietnam’s environmental law classifies investment projects by environmental risk level. Projects in higher-risk categories — including many chemical, textile, food processing, metalworking, and surface treatment operations — require an Environmental Impact Assessment (EIA) or Environmental Protection Plan (EPP) approved before construction begins. The classification triggers based on production type, volume, and location. Investors who begin site preparation or construction before confirming environmental classification — and completing required pre-approvals — risk construction suspension and licence amendment requirements. Turkish textile manufacturers and Korean electronics producers are among the most common nationality groups that encounter unexpected environmental pre-approval requirements in Vietnam.
What are the most commonly missed post-licensing steps?
After ERC issuance, companies consistently underestimate the number of legal and administrative steps required before they can legally operate. The most commonly missed are: DICA (Direct Investment Capital Account) opening and capital contribution registration; tax authority registration and e-invoice activation; social insurance registration; customs code registration; fire safety inspection and acceptance; environmental compliance confirmation; and internal labour regulations registration with the provincial labour authority. Companies that attempt to operate — hiring staff, importing machinery, or invoicing — before all these steps are complete face retroactive penalties and potential production suspension. The post-ERC checklist typically requires six to ten weeks to complete when all steps are properly sequenced.
Machinery Import and Customs
Can factory machinery be imported before the factory is ready to operate?
It depends on the project stage and the terms of the IRC. Machinery import for a foreign-invested manufacturing project requires: the IRC with a scope that covers the machinery type; a customs declaration linking the machinery to the project; and in some cases, advance notification or equipment list registration with the applicable authority. Machinery imported under a project-linked duty exemption must enter within the project’s exemption window — imports before the project is formally registered or after the exemption window closes may not qualify. Storage and installation arrangements for pre-positioned machinery must also be addressed before import, as customs bond and warehousing requirements apply.
What is the correct approach to duty exemption for manufacturing equipment?
Machinery and equipment imported to create fixed assets for a qualifying foreign-invested manufacturing project may be exempt from import duties. Eligibility depends on the equipment falling within the approved project scope, the HS code classification of the equipment, and the project’s tax incentive status. The exemption must be confirmed before import — not claimed retrospectively. A common error is importing machinery under a general import declaration rather than a project-linked exemption declaration, then attempting to reclassify after customs clearance. This is difficult to reverse and may result in duty liability plus penalties.
Operational Readiness
What is the main operational bottleneck after licensing?
The most consistent bottleneck is the gap between ERC issuance and actual legal operation — a gap that many investors underestimate. The ERC confirms the company exists; it does not confirm that the company can manufacture, import, hire, or invoice. The steps between ERC issuance and first legal operation — tax registration, e-invoice activation, customs registration, social insurance, fire safety acceptance, environmental compliance, internal labour regulations — must each be completed in sequence before the relevant activity can begin. Companies that build their production launch timeline from ERC issuance date, rather than from completion of all post-ERC compliance steps, consistently encounter delays of four to eight weeks between ERC issuance and actual operational readiness.
What launch checklist should a manufacturer prepare?
A legally compliant Vietnam manufacturing launch checklist covers: IRC and ERC issuance and certified copy filing; DICA opening and capital contribution completion; tax registration and CIT incentive confirmation filing; e-invoice registration and activation; customs code registration and first shipment documentation; environmental compliance certificate or EPP registration; fire safety acceptance; construction completion certificate; internal labour regulations registration; social insurance and health insurance registration for first employees; employment contracts for all staff in compliant form; and work permits or exemption confirmations for all foreign personnel. This checklist should be prepared and tracked from the IRC application stage — not assembled reactively after ERC issuance.
Frequently Asked Questions
How long does Vietnam factory licensing typically take?
From IRC submission to ERC issuance in a standard manufacturing project in an industrial zone with complete documentation: four to eight weeks. From ERC issuance to full operational readiness (all post-ERC compliance completed): six to ten additional weeks. Total time from IRC submission to first legal operation: typically fourteen to twenty-two weeks for well-prepared projects. Projects requiring MOIT pre-approval, EIA, or construction permits take longer.
What is the biggest legal mistake manufacturing investors make in Vietnam?
Committing to a factory site — signing a lease or paying a reservation deposit — before confirming that the intended production scope is licensable in that location, that the environmental classification is compatible with the site, and that the industrial park’s infrastructure is legally complete. These three confirmations take two to three weeks with proper legal review. Skipping them to accelerate timeline creates obligations — and lease costs — that run whether or not the project proceeds.
Is a joint venture with a Vietnamese partner required for manufacturing?
No, for most manufacturing sectors. Foreign investors can own 100% of a Vietnam manufacturing company in most product categories. Joint ventures remain common for sectors with ownership conditions, for projects seeking a local partner’s land contribution or government relationship, or for investors who want Vietnamese market knowledge before scaling. Where a JV is chosen voluntarily, the governance structure — decision rights, capital contribution schedule, deadlock mechanism, IP ownership, and exit — must be carefully drafted before the relationship begins, not after the first operational disagreement.
