Vietnam E-Invoice Exemption for Heat Dissipation Components

On May 22, 2026, the Ministry of Finance of Vietnam issued Decree No. 45/2026/ND-CP, granting a temporary exemption from mandatory electronic invoicing for B2B exports of heat dissipation components — including aluminum substrate heat sinks, heat pipe modules, and liquid cold plates (HS codes 8415/8418). This measure preserves paper-based, bilingual (Chinese–Vietnamese) commercial invoices approved by Vietnamese Customs, offering critical documentation flexibility to Chinese exporters amid broader e-invoicing rollout.

Event Overview

Vietnam’s Ministry of Finance formally announced Decree No. 45/2026/ND-CP on May 22, 2026. The decree confirms that B2B exports of heat dissipation industrial goods — specifically those classified under HS codes 8415 and 8418 — are exempted from the national e-invoice mandate. Such exports may continue using Vietnamese Customs–approved bilingual (Chinese–Vietnamese) paper commercial invoices. The exemption remains valid until December 31, 2027.

Industries Affected

Direct Trading Enterprises: Exporters based in China engaging in B2B sales of heat dissipation components to Vietnamese industrial buyers face reduced compliance overhead. The exemption avoids immediate investment in Vietnam-compliant e-invoicing infrastructure, translation APIs, or local ERP integration — preserving margin and operational speed during transition periods.

Raw Material Procurement Enterprises: Firms sourcing base materials (e.g., aluminum alloys, copper tubing, thermal interface materials) for downstream heat dissipation assembly are indirectly affected. While not issuing invoices themselves, their contractual terms with manufacturers may now include clauses referencing invoice format compatibility — prompting earlier alignment on bilingual labeling, traceability standards, and customs documentation readiness.

Contract Manufacturing & Assembly Enterprises: OEM/ODM facilities producing heat pipe modules or liquid cold plates for export must ensure their internal billing systems support dual-language paper invoice generation — particularly where final consignee data, product specifications, and unit pricing must meet both Vietnamese Customs and Chinese tax authority requirements. The exemption does not relax audit-readiness expectations.

Supply Chain Service Providers: Freight forwarders, customs brokers, and trade finance institutions handling documentation for this product category must update internal checklists to verify bilingual paper invoice authenticity (e.g., stamp placement, bilingual line-item consistency, signature validity), rather than validating e-invoice XML schemas or digital signatures. Training and SOP adjustments are required ahead of the 2027 expiry.

Key Considerations and Recommended Actions

Maintain Dual-Language Paper Invoice Compliance Rigor

Although exempt from e-invoicing, enterprises must ensure all bilingual paper invoices strictly adhere to Vietnamese Customs’ formatting, content, and authentication rules — including correct HS code application, consistent terminology across languages, and authorized signatory validation. Non-compliance risks delayed clearance or reclassification.

Monitor Expiry Timeline and Phase-Out Signals

The exemption expires on December 31, 2027. Companies should treat this as a defined runway: initiate feasibility assessments for Vietnam e-invoicing adoption by Q3 2026, especially evaluating interoperability with existing ERP (e.g., SAP S/4HANA, Oracle Cloud) and local Vietnamese service providers.

Align Internal Documentation with Upstream and Downstream Partners

Manufacturers exporting via trading companies must synchronize invoice templates, product coding, and batch-level traceability with both suppliers (for material origin declarations) and Vietnamese end-buyers (for warranty and after-sales registration). Discrepancies between paper invoice data and packing list or BL details remain enforceable grounds for customs rejection.

Verify Customs Recognition Status of Existing Invoice Templates

Not all bilingual paper invoices currently in use are pre-approved. Exporters should submit sample templates to their appointed Vietnamese customs broker or directly to the General Department of Vietnam Customs for formal recognition confirmation before large-scale deployment — particularly where non-standard fields (e.g., thermal performance metrics, RoHS compliance statements) are included.

Editorial Perspective / Industry Observation

Observably, this exemption reflects Vietnam’s pragmatic calibration of digital transformation goals against sectoral readiness — prioritizing continuity for high-volume, mid-tech industrial exports over blanket digitization mandates. Analysis shows the decision likely stems from feedback during the 2025 pilot phase, where heat dissipation exporters reported disproportionate implementation costs relative to transaction value and limited local IT support capacity among Vietnamese procurement departments. From an industry standpoint, the extension is better understood as a targeted stabilization tool rather than a long-term policy shift: it buys time for ecosystem-wide alignment, not indefinite deferral.

Conclusion

This exemption offers tangible short-to-midterm relief but does not alter the structural direction of Vietnam’s tax administration modernization. For Chinese heat management solution providers, the period through 2027 represents a strategic window — not for postponement, but for deliberate, phased preparation. A rational interpretation is that regulatory flexibility here serves as both a buffer and a benchmark: how effectively firms use this time will signal their resilience in increasingly digitized ASEAN trade corridors.
