Vietnam E-Invoice Exemption for Heat Dissipation Components

Vietnam’s Ministry of Finance issued Notification No. 127/2026/TT-BTC on May 21, 2026, exempting B2B exporters of heat dissipation components — including heat sinks, heat pipes, and vapor chambers — with annual export value under USD 500,000 from mandatory electronic invoicing. Affected enterprises may continue using Chinese-Vietnamese bilingual paper invoices pre-registered with Vietnamese customs. The exemption is extended through end-2027, offering administrative relief to small and medium-sized manufacturers exporting thermal management solutions to Vietnam.

Event Overview

On May 21, 2026, Vietnam’s Ministry of Finance published Notification No. 127/2026/TT-BTC. It formally exempts B2B exporters of heat dissipation components (specifically heat sinks, heat pipes, and vapor chambers) whose annual export value to Vietnam falls below USD 500,000 from the requirement to issue electronic invoices (e-Invoices). These enterprises remain permitted to use bilingual (Chinese–Vietnamese) paper invoices, provided such invoices have been pre-registered with Vietnamese customs authorities. The exemption period runs through December 31, 2027.

Industries Affected

Direct Exporters (B2B Thermal Component Manufacturers)

Manufacturers in China, Taiwan, South Korea, and other jurisdictions that ship heat sinks, heat pipes, or vapor chambers directly to Vietnamese business buyers are directly covered by this exemption. They are relieved from implementing e-invoicing systems, integrating with Vietnam’s e-invoice platform, or retraining staff on new digital compliance workflows — all of which carry cost and timeline implications.

Contract Manufacturers & ODMs Serving Global Brands

Contract manufacturers producing thermal components under private label or OEM arrangements for multinational electronics brands may qualify if their direct shipments to Vietnamese subsidiaries or distributors fall below the USD 500,000 threshold. Their invoicing process remains unchanged, but eligibility depends on how sales value is attributed per legal entity and shipment route — not total group-level exports.

Export-Focused Distributors & Trading Companies

Distributors handling cross-border sales of thermal components (e.g., consolidating orders from multiple factories for delivery to Vietnamese clients) must assess whether their own invoicing entity — not the underlying factory — meets the USD 500,000 cap. If so, they retain flexibility to use pre-registered bilingual paper invoices without system upgrades.

Key Considerations and Recommended Actions

Monitor official guidance on invoice registration renewal

The exemption applies only to paper invoices pre-registered with Vietnamese customs. Exporters should verify whether existing registrations remain valid through 2027 or require re-submission ahead of renewal deadlines — especially if company details, product codes, or authorized signatories have changed since initial filing.

Verify eligibility at the legal-entity level

Eligibility is determined per exporting legal entity, not per product line or brand. Companies operating multiple subsidiaries or trade names must calculate annual export value separately for each registered exporter. Consolidated group figures do not apply.

Distinguish between policy intent and operational readiness

While the exemption delays e-invoicing obligations, Vietnam continues advancing its national e-invoice rollout. Enterprises should track technical specifications (e.g., XML schema, digital signature requirements) for future compliance, even while using paper invoices — particularly if scaling beyond the USD 500,000 threshold.

Maintain consistent bilingual invoice formatting

Approved paper invoices must retain both Chinese and Vietnamese text, with identical commercial terms (product description, quantity, unit price, total amount, and tax treatment) in both languages. Any deviation risks rejection at customs clearance — regardless of exemption status.

Editorial Observation / Industry Perspective

Observably, this exemption reflects Vietnam’s pragmatic approach to balancing digital tax administration with SME capacity constraints in specialized manufacturing sectors. It is not a reversal of e-invoicing policy, but rather a targeted, time-bound accommodation. Analysis shows the measure primarily signals regulatory awareness of supply-chain friction points in thermal management hardware — a niche yet critical segment for electronics assembly and data infrastructure. From an industry perspective, the extension through 2027 suggests continued monitoring is warranted: further adjustments may follow based on adoption rates among larger exporters or changes in regional trade volume trends.

Concluding, this notification does not alter Vietnam’s long-term e-invoicing trajectory but provides near-term operational stability for qualifying exporters of heat dissipation components. It is best understood not as a permanent alternative to digital compliance, but as a calibrated transition window aligned with enterprise scale and export maturity.
