Post Market Surveillance (PMS) serves to promote an active teamwork among stake holders – the local government, manufacturers, authorized representatives (AR) and distributor, each taking respective obligations to maintain safe and high-quality products in the local market. PMS carries on a succession of strategies throughout the product life cycle until such time that the product finally exits the market. In a global sense, Post Market Surveillance System covers all aspects of product monitoring, annual reporting, adverse event reporting, and product recalls, with some slight variations across different countries.

Recently, a new definition of PMS has been added in ISO 13485:2016 – “Systematic process to collect and analyse experience gained from medical device that have been placed on the market”, so as to include nonconforming products, feedback, complaint handling, and data analysis within its scope thereby encouraging manufacturers to maintain high quality and safe products. This is roughly analogous to PDCA – a never ending cycle for process improvement.

Local Authorized Representatives are the ones obliged to assist foreign manufacturers in facilitating Post Market Surveillance Activities. AR plays an important role by liaising foreign manufacturers with local Health Authorities. With the impending enforcement of rigorous PMS measures, a broader range of responsibilities would be expected for AR’s. Understanding the expected qualifications and legal competencies of a local Authorized Representative would prove beneficial in accessing the target market.  

As per current regulations, all Health Authorities require foreign manufacturers to appoint a local entity who act as an Authorized Representative of a Locally Registered Foreign Product. The AR takes responsibility of constantly getting in touch with the manufacturer to inform them of product-related regulations issued by the government and local health agencies. 

In the succeeding paragraphs, we will quickly go over the current system of Post Market surveillance across three different countries in Asia – China, Singapore, Indonesia, with special emphasis on the responsibilities of Local Authorized Representatives. 



In 2008, CFDA has published the “The Measures of Adverse Event Monitoring and Re-evaluation of Medical Device”. The high volume of medical device-related complaints and adverse events has prompted the NMPA to establish a PMS system in order to facilitate an effective approach for managing these issues.

NMPA highly focuses on the obligations of the Legal agent (common term used in China also referred to as “Authorized Representative”).[Q1]  In fact, in 2018, the agency has already issued a draft guidance on the duties and responsibilities of Legal Agents. Although the guidance hasn’t been implemented yet, we can see how Chinese Government proactively responds to keep the current Post Market Surveillance System moving forward.

AR Rights, Obligations, and Qualifications

The obligations of Legal Agent covers the submission of annual product analysis report to NMPA, sending of Chinese regulatory updates to foreign manufacturers, and providing assistance in product registrations , such as license renewal or amendment. Moreover, the Legal Agent shall assist in PMS activities whenever an adverse event or product recall has occurred, and communicate the recall incident or adverse event information to the manufacturer and NMPA.

Currently, the obligation of Legal Agent doesn’t include the importation or distribution related activities. NMPA only authorizes the NMPA-accredited firms to distribute medical devices across the country. With close observation of the future trend, however, NMPA seemed to widen the scope of Legal Agents’ responsibilities in order to improve the current PMS system. Based on the newly published draft guidance of Authority Responsibility in 2018, the Legal Agents shall also be involved in the importation, management of distributors, management of unique distribution identification of each product…and so on.

How the Government carries out PMS:

NMPA focuses on post market inspections which covers factory on-site and product inspections conducted yearly. NMPA publishes the overseas inspection guidance of medical device manufacturer to ensure that foreign manufacturers follow Good Manufacturing Practice. In addition, NMPA randomly conducts product inspection throughout the country. For the post market surveillance, NMPA collects the product recall and adverse event report from the Legal Agent. Sometimes, they would ask manufacturers to re-evaluate the safety and effectiveness of the medical device in order to assess whether the medical device needs further modifications.

NMPA branches situated in the provinces oversee the issuance of the distributor licenses and conduct distribution inspection. NMPA branch would report the inspection records to NMPA main institute.

Before we move on to the next Asian country, one thing needs to be clarified. The term “License Holder” refers to a firm having a legal capacity to manage the product license.

License Holder Responsibilities in ASEAN countries may be designated to either the Importer or the Authorized Representative (AR). In Philippines, Indonesia and Thailand, the importer assumes responsibility of the License Holder. 

Singapore, Malaysia and Vietnam, on the other hand, requires an AR to hold the license. AR can authorize other qualified device distributor to do the import and distribution locally. For this issue, we will focus on Singapore and Indonesia’s PMS system while incorporating some information on the responsibilities of Authorized Representatives in the respective countries.



With the country’s high dependence on international trade, Singapore HSA has developed a comprehensive system for post-market surveillance. SG Medical Device Establishments comprise different roles in the market:

  • Manufacturer: Any company who manufacturers medical device in Singapore;
  • Importer: Any company who imports medical devices into Singapore;
  • Registrant: In relation to a registered health product, means the person who applies for and carries out registration activities in accordance with the Health Products Act;
  • Wholesaler: Any company who supplies medical devices in bulk quantities (which includes export) in Singapore.

Singapore HSA has amended the current guidance documents in order to help the agency effectively regulate the legal scope of license and company qualification and to further assist companies to get the corresponding license they are applying for.

AR Rights, Obligations, and Qualifications

Authorized Representative assumes responsibility as a Registrant. Registrants’ scope of obligations cover not only the registration part but also product recalls, field safety corrective actions (FSCA) and mandatory adverse event reporting. As per HSA regulations, only the importer and wholesaler could carry out distribution activities. If AR’s wish to expand their scope of service as a distributor, they should obtain the certificate of Good Distributor Practice Medical Device (GDPMD). Only Class A medical devices are exempted from this requirement.

How the Government carries out PMS:

Importers and wholesalers are required to compile all distribution records which will later be inspected by Conformity Assessment Body (CAB) according to GDMPDS. The registrant shall also notify HSA all reportable adverse events and recalls , and provide all the necessary documentations requested by the HSA. Manufacturers, in turn, shall do appropriate actions to correct the errors and reduce risks associated with the use of the device. Finally, the manufacturer shall submit the Field Safety Corrective Action (FSCA) and Field Safety Notice to HSA via the registrant. Safety communication of FSCAs  reported to the HSA are publicly accessible as filed safety notices (FSN) on the HSA website.
