Avoid 3-Month Delays in Class C and D Medical Device Registration in Vietnam

Class C and D medical device registration in Vietnam can take longer than expected, often up to three months more, if your documentation is grouped incorrectly or does not comply with the Ministry of Health’s (MOH) requirements. Green NRJ helps you avoid these costly delays by guiding you through every step of the registration process, ensuring faster approvals and full compliance with Vietnamese regulations.

Why Registering Class C and D Medical Devices in Vietnam Is Challenging

Vietnam is one of the fastest-growing medical markets in Southeast Asia, but entering it requires a detailed understanding of the local regulatory system. Registering Class C and Class D medical devices in Vietnam is particularly complex due to their classification as high-risk. These devices are subject to rigorous Market Authorization requirements from the Ministry of Health (MOH) and the Department of Medical Equipment and Construction (DMEC).

Foreign manufacturers and distributors often encounter serious delays in medical device registration in Vietnam, usually due to grouping errors or legal gaps in their application. Understanding and meeting the MOH’s expectations is key to success.

Common Mistakes That Cause Delays

Vietnam’s regulations for medical device registration have become increasingly rigorous, especially for Class C and D devices, which are classified as high-risk. Although the regulatory framework is clearly outlined in Decree 98/2021/ND-CP, real-world application is subject to the interpretations of the MoH’s expert review councils.

1. Improper Product Grouping Is the Leading Cause of MOH Registration Rejection

A major, yet often overlooked, cause of delay in Class C and D medical device registration in Vietnam is incorrect product grouping at the dossier submission stage. Many applications that appear to be nearing approval, even after 4 to 6 months of processing, are unexpectedly returned with the comment “Request to separate product groups.” 

This issue typically arises when products are made from different materials and therefore do not qualify as variants within the same medical device family, or when devices are intended for different anatomical locations or clinical purposes, in violation of the grouping rules set by the Ministry of Health of Vietnam. 

In such situations, even a nearly complete dossier must be restructured, requiring the separation of devices into distinct registration sets. This process entails additional documentation and translation work and can extend timelines by up to three months for each resubmission. 

If not properly addressed from the outset, errors in product grouping can significantly disrupt market entry strategies, leading to prolonged timelines, increased costs, and delayed patient access.

2. Incorrect Classification of Medical Devices

Another major issue is incorrect classification of medical devices. Many foreign manufacturers mistakenly classify their Class C or Class D devices as Class A or B in the application dossier. Once submitted, the Ministry of Health (MOH) will reject the application, stating the classification is incorrect and requires a complete resubmission, causing at least 3 additional months of delay.

3. Invalid or Incomplete Legal Documents

Even when product grouping and classification are correctly determined, many applications for Class C and D medical device registration in Vietnam still face delays due to incomplete or invalid documentation. Common issues include the absence of a valid Certificate of Free Sale (CFS), expired ISO 13485 certification, lack of consular legalization or Vietnam-legalized documents, unclear or unsigned Letters of Authorization (LOA), and insufficient technical documentation or testing reports. 

When any of these deficiencies arise, the Ministry of Health (MOH) may request resubmission or place the application on hold, typically resulting in an additional delay of 2–3 months. In many cases, these shortcomings only become evident during the importation stage of Class C and D medical devices into Vietnam, when customs authorities conduct a secondary review of the dossier and identify inconsistencies. 

Therefore, ensuring that all required documentation is complete, valid, and up to date is critical to achieving an efficient and fast-track medical device registration process in Vietnam.

How to Avoid TGA-like Delays: Proactive Steps for Faster Market Authorization

To reduce the risk of product grouping rejection and ensure a smooth Class C and D medical device registration process in Vietnam, businesses should adopt a strategic and compliant approach from the outset. This includes carefully analyzing the product portfolio to determine the most appropriate grouping method based on device structure, materials, and intended use, while avoiding the inclusion of products made from different materials or designed for different anatomical applications within the same group.

In addition, medical devices should be named in strict accordance with Ministry of Health (MOH) guidelines, as clear and standardized nomenclature enables reviewers to efficiently assess conformity. It is also essential to prepare a legally compliant dossier from the beginning, ensuring that all required documents are complete, properly translated, and formatted in line with regulatory requirements to minimize the likelihood of additional requests or clarifications. 

Implementing these measures early in the process can significantly improve the chances of obtaining timely market authorization and help avoid delays of up to three months.
