With Vietnam’s expanding market openness and the booming development of its new energy industry, Chinese battery enterprises are encountering unprecedented opportunities for exporting to Vietnam. However, to successfully enter this market, SDOC certification has become an indispensable pass. As Guangdong Energy Storage Testing Technology Co., Ltd., we leverage our extensive testing and certification experience to deeply analyze the three core considerations for battery export to Vietnam via SDOC certification, helping you efficiently and compliantly explore the Vietnamese market.

Understanding Vietnam SDOC Certification

SDOC (Supplier's Declaration of Conformity) is a basic market access requirement imposed by Vietnamese regulatory authorities on imported products. Unlike traditional certification methods, SDOC certification emphasizes the supplier’s self-declaration responsibility, supported by authoritative test reports as technical evidence. This certification mechanism ensures product quality and safety while improving market access efficiency.

3 Core Requirements for Battery SDOC Certification

1. One Model, One Report Principle

A fundamental rule in Vietnam’s SDOC certification system is that one test report corresponds to only one battery model. This means batteries with different capacities, specifications, or designs must undergo separate testing and obtain independent test reports.

In practice, many enterprises mistakenly assume that a single report can cover a product series, leading to customs clearance delays. We recommend enterprises fully consider this requirement during product planning, arrange testing schedules reasonably, and avoid unnecessary losses caused by model confusion.

2. Exclusive Report Ownership

Another critical feature of Vietnam SDOC certification is that the report holder must be a Vietnamese importer, and the report cannot be authorized for use by other enterprises. This regulation clarifies liability ownership, meaning Chinese battery manufacturers cannot hold the report independently like they do for other international certifications.

This system design makes selecting a suitable Vietnamese partner particularly important. Enterprises should establish long-term cooperation with reputable Vietnamese importers with stable partnerships, and clearly define relevant responsibilities and obligations in commercial agreements to protect their legitimate rights and interests.

3. Dynamic Validity Mechanism

Unlike traditional certifications, SDOC test reports have dynamic validity—they automatically expire with standard updates and are not permanently valid. When Vietnam adopts new technical standards or updates existing ones, the original test reports become invalid, and re-testing in accordance with the new standards is required.

This feature mandates that export enterprises continuously monitor updates to Vietnamese technical regulations and standards, establish a sound standard tracking mechanism, and ensure products always comply with the latest market requirements.

Strategic Recommendations for Efficient SDOC Certification

1. Plan Certification in Advance

Considering testing cycles and potential rectification time, initiate certification preparations 2–3 months before product export.

2. Choose a Professional Testing Institution

As Guangdong Energy Storage Testing Technology Co., Ltd., we possess advanced testing equipment and extensive experience in Vietnamese certification. We provide accurate and efficient testing services, avoiding repeated investments due to failed tests.

3. Establish a Standard Monitoring System

Designate a dedicated position to track standards or entrust professional institutions to monitor changes, ensuring timely access to the latest updates on Vietnamese technical regulations.

4. Improve Technical Document Management

Ensure complete and accurate product technical documents, including product specifications, circuit diagrams, and lists of key components—these are crucial for testing and declaration.

Vietnam’s battery market holds enormous potential, but only by fully understanding and complying with SDOC certification requirements can enterprises ensure smooth entry and long-term stable development.
