AT A GLANCE
SS 620:2016 Good Distribution Practice for Medical Devices (GDPMDS) is a Singapore Standard that became a regulatory requirement under HSA’s Medical Device Dealer Licensing framework. This case study demonstrates how industry partnership in standardisation can drive national regulatory outcomes that protect patients while supporting business growth.
The Challenge
Closing the Gap in Medical Device Distribution
Before SS 620, Singapore’s medical device distribution landscape faced a critical gap. While international standards like ISO 13485 provided robust frameworks for manufacturing, they did not adequately address downstream activities—the warehousing, transport, and post-market handling that determine whether a device reaches patients safely.
Health Sciences Authority (HSA) had developed Technical Specification TS-01 (Good Distribution Practice for Medical Devices) as an early regulatory response—making Singapore one of the first countries globally to establish Good Distribution Practice (GDP) requirements specifically for medical devices. TS-01 proved its value: it was pragmatically designed for local importers and distributors, and was widely referenced by other countries developing their own medical device regulations.
However, by the mid-2010s, the regulatory landscape had evolved significantly. Distribution models grew more complex. Regional and international interest in medical device regulation increased. HSA and local industry groups recognised the opportunity to elevate TS-01 into something more enduring: a Singapore Standard that could enable third-party certification, support consistent enforcement, and evolve alongside industry practices.
SS 620:2016 was developed through the strong partnership between the regulator (HSA), industry associations (Singapore Manufacturing Federation), and practitioners from across the medical device supply chain. This working group brought together expertise from importers, distributors, certification bodies, and quality professionals.
The standard was purposefully designed to:
- Build on the proven foundation of TS-01 Rev 2.1, preserving practical requirements that worked well for local businesses
- Incorporate relevant ISO 13485 principles, tailored specifically for distribution rather than manufacturing
- Address the complete distribution lifecycle, including premises and facilities, resource management, traceability, and post-market surveillance
- Scale appropriately—practical enough for small importers, yet robust enough for large, complex organisations

HSA’s Perspective
The Regulatory Integration
2024 Health Sciences Authority (HSA) – Singapore Accreditation Council (SAC) dialogue session with Accreditation Bodies.
From the regulator’s perspective, SS 620 serves as a national safeguard for patient safety by strengthening controls over how medical devices are distributed before reaching patients.
HSA integrated SS 620 directly into its Medical Device Dealer Licensing framework. Under this approach:
- Importers and wholesalers of Class B, C, and D medical devices must hold a valid SS 620 certificate before a licence can be issued or renewed
- Certification must be obtained from Singapore Accreditation Council (SAC)-accredited certification bodies
- Lower-risk Class A devices may conform through self-declaration
This risk-based approach rapidly elevated distribution standards across the industry, bringing hundreds of importers and wholesalers into structured quality management systems. For patients, this provides confidence that medical devices supplied in Singapore are properly stored and handled according to defined safety requirements throughout the supply chain.
SS 620 works alongside other regulatory controls—product registration, adverse event reporting, and Field Safety Corrective Actions—forming a comprehensive lifecycle approach to medical device regulation. To maintain system integrity, HSA conducts witnessed audits of SAC-accredited certification bodies, ensuring consistent application of certification standards.
As one of the earliest SAC-accredited certification bodies for SS 620, TÜV SÜD PSB provides independent assurance within Singapore’s GDPMDS ecosystem.
Certification follows a two-stage audit process:
- Stage 1: Documentation review—site master files, SOPs, internal audits, and management reviews
- Stage 2: On-site verification—storage conditions, environmental controls, training records, traceability, and product disposal
With over 100 organisations certified, TÜV SÜD observes that most clients not only maintain compliance but also show measurable improvements year-on-year. This reinforces SS 620’s role as both a regulatory requirement and a driver of continuous quality improvement.
Beyond Singapore, some companies operating in other countries refer to SS 620 as a practical benchmark when developing or strengthening their medical device distribution practices, particularly where detailed local guidance is still evolving.

The Industry Adopter’s Perspective
Abbott’s Implementation Journey

For multinational companies such as Abbott (Singapore) Pte Ltd, SS 620 functions as a local regulatory baseline integrated into their established global Quality Management System.
From Abbott’s perspective, elevating these requirements into a national standard provided clearer and more consistent expectations for industry—particularly in areas not fully addressed by manufacturing-focused frameworks, including premises and facilities management, post-market surveillance, and system governance.
Operationally, implementing SS 620 has created opportunities for process streamlining and improved resource management, including better inventory control. These improvements contribute to greater cost efficiency while reinforcing regulatory compliance.
Practical Advice for Organisations Implementing SS 620
Based on its compliance experience, Abbott highlights two areas that often require particular attention:
- Management of outsourced activities and third-party suppliers—these entities operate outside direct control and can introduce gaps if quality responsibilities are not clearly defined. Reviewing contracts and quality agreements early helps clarify expectations.
- Internal audit capability—SS 620 requires audits to be conducted by appropriately trained personnel. A phased approach to training and audit implementation can help organisations build capability in a manageable way.
SS 620 has established itself as Singapore’s most widely implemented healthcare standard, with adoption by over 500 unique organisations—demonstrating its deep and extensive reach across Singapore’s medical device ecosystem.
A key differentiator is SS 620’s cross‑industry applicability. While medical device manufacturers remain the core user group, the standard has also been widely embraced by logistics providers, supply chain operators, and distribution partners. This widespread update underscores a shared recognition that device quality and patient safety rely not only on robust manufacturing controls but on excellence at every stage of the distribution chain.
Today, SS 620 serves as the common quality backbone that unifies Singapore’s medical device distribution ecosystem.
Looking Ahead
As Medtech supply chains continue to digitalise and decentralise, SS 620 remains a living framework that can evolve with industry practices. Future refinements are likely to focus on outsourced activities, workforce capability, and demonstrating compliance in increasingly remote and technology-driven environments.
Together, regulators, certifiers, and industry adopters form an interconnected system—one where SS 620 functions not just as a document, but as part of the national quality infrastructure safeguarding Medtech distribution in Singapore.

Relevant Standards for Implementation
FOR MEDICAL DEVICE DEALERS: COMPLIANCE REMINDER SS 620 certification is mandatory for importers and wholesalers of Class B, C, and D medical devices. Ensure your certification from a SAC-accredited body is current before licence renewal. Visit www.hsa.gov.sg for complete licensing requirements.
The following standards are highly relevant to SS 620 and should be considered for adoption. Please click the images to access the standards.
