Vietnam Raises Local Assembly Threshold for Industrial Robot Tax Refunds to 45%

Vietnam’s Ministry of Industry and Trade (MOIT) issued Circular No. 28/2026/TT-BCT on May 14, 2026, raising the local assembly requirement for industrial robots eligible for export tax refunds from 40% to 45%. The update mandates third-party BOM localization audit reports from accredited Vietnamese institutions. This policy shift directly affects Chinese robot body manufacturers exporting to or operating in Vietnam—and presents new considerations for system integration service exporters.

Event Overview

On May 14, 2026, Vietnam’s Ministry of Industry and Trade (MOIT) published Circular No. 28/2026/TT-BCT. The circular formally amends the ‘localization-linked export tax refund’ scheme by increasing the minimum local assembly rate for industrial robots from 40% to 45%. It also specifies that eligibility requires a Bill of Materials (BOM) localization audit report issued by a certified third-party institution in Vietnam. No further implementation details, transitional provisions, or exemptions were included in the publicly released text.

Industries Affected by This Policy Change

Direct Exporters of Industrial Robot Bodies (e.g., Chinese OEMs)

These companies face increased compliance pressure: meeting the 45% local assembly threshold—up from the previously proposed 40%—requires deeper local investment or tighter joint-venture arrangements in Vietnam. The mandatory third-party BOM audit adds verification complexity and cost, particularly for firms relying on imported core components (e.g., reducers, controllers, or servo motors).

Local Contract Manufacturers & Assembly Service Providers in Vietnam

They may experience higher demand for value-added assembly services—including localized sourcing coordination and documentation support—but only if they can credibly demonstrate traceable, auditable local content across the BOM. The 45% threshold raises the bar for qualifying as a compliant local partner.

System Integration Service Exporters (e.g., Vietnamese or regional integrators)

Unlike robot body exports, system integration services are not subject to the same localization requirements under this circular. As robot body importers face higher compliance costs, end users may shift procurement toward integrated turnkey solutions—potentially expanding opportunities for service-based exports, provided those offerings remain outside the scope of the robot body tax refund regime.

Supply Chain Verification & Certification Service Providers

The requirement for third-party BOM localization audits creates a new operational dependency. Firms offering supply chain transparency, component traceability, or localization certification services—especially those accredited by Vietnamese authorities—may see growing demand, though the list of approved auditors has not yet been published.

What Relevant Companies or Practitioners Should Focus On and How to Respond

Monitor MOIT’s official guidance on accredited auditing institutions

The circular mandates third-party BOM audit reports but does not name or list authorized Vietnamese auditing bodies. Companies should track MOIT’s subsequent announcements or technical guidelines to identify qualified providers—avoiding delays in certification or non-compliant submissions.

Review current BOM composition against the 45% threshold with granular localization mapping

Assess each component’s country of origin, manufacturing location, and Vietnamese customs classification—not just invoice origin. Localization is determined by actual assembly and value-add within Vietnam, not merely labeling or final packaging. Firms should map BOMs at sub-assembly level to identify gaps before applying for refunds.

Distinguish between policy intent and enforceable criteria

This circular sets a formal threshold, but enforcement mechanisms—including audit frequency, penalties for misrepresentation, and treatment of hybrid supply chains (e.g., CKD/SKD kits)—remain unspecified. Treat the 45% figure as a compliance benchmark, not yet a fully operational standard until supplementary technical notices are issued.

Prepare documentation workflows for BOM audits ahead of first refund application

Begin compiling supplier declarations, import records, local procurement invoices, and production logs covering at least six months prior to submission. Third-party auditors will require verifiable, time-stamped evidence—not estimates or internal assessments—to validate local content claims.

Editorial Perspective / Industry Observation

Observably, this adjustment signals Vietnam’s continued prioritization of domestic manufacturing depth over volume-based import substitution. Raising the threshold from 40% to 45%—rather than freezing it—suggests MOIT views the original draft as insufficient to drive meaningful local value addition in high-tech equipment assembly. Analysis shows the change is less about immediate revenue impact and more about shaping long-term investment behavior: it incentivizes foreign robot makers either to localize more deeply in Vietnam or to restructure commercial models around service-led delivery. From an industry perspective, this circular functions primarily as a regulatory signal—not yet a fully implemented operational framework—given the absence of implementing procedures, approved auditor lists, or dispute resolution protocols. Continued attention is warranted as MOIT releases technical annexes or responds to stakeholder consultations.

Ultimately, this policy update reflects Vietnam’s calibrated approach to industrial upgrading: tightening conditions incrementally while leaving room for phased adaptation. It does not block market access outright, but recalibrates the cost-benefit balance for foreign robot suppliers. For stakeholders, it is better understood as a directional nudge toward localized capability development—not a sudden barrier or a finalized trade restriction.
