Good Distribution Practice (GDP) certification is not optional for every organisation operating in Singapore. For importers and wholesalers of therapeutic products, Chinese proprietary medicines, cell, tissue and gene therapy products, and active pharmaceutical ingredients, GDP compliance is a mandatory requirement for obtaining and maintaining a local dealer’s licence under the Health Sciences Authority (HSA).
For medical device importers and wholesalers, GDPMDS certification is also mandatory before a Medical Device Dealer’s Licence can be issued.
Determining which GDP framework applies to your Singapore operation is the first step. Some businesses are subject to mandatory GDP compliance, while others may pursue a voluntary GDP certificate to demonstrate their distribution standards. Global Quality Services begins every engagement by establishing the correct regulatory route for your business.
We provide end-to-end GDP certification consultancy for pharmaceutical importers, wholesalers, third-party logistics providers, and medical device dealers in Singapore. Our consultants help you develop the required quality system, prepare documentation, get your operations ready for the HSA audit, and maintain compliance when your products, processes, or distribution activities change.
What Is GDP Certification?
Good Distribution Practice forms an important part of pharmaceutical and healthcare product quality assurance. It requires organisations to establish and maintain a quality system that ensures products are stored, handled and distributed under suitable conditions in accordance with the applicable marketing authorisation or product specifications.
In Singapore, GDP certification and compliance follow two distinct regulatory tracks administered by HSA.
- Pharmaceutical GDP — governed by HSA’s Guidance Notes on Good Distribution Practice, revised in December 2023. It applies to importers and wholesalers of therapeutic products, Chinese proprietary medicines, cell, tissue and gene therapy products (CTGTP), and active pharmaceutical ingredients intended for the Singapore market.
- Medical Device GDP (GDPMDS) — governed by Singapore Standard SS 620:2016. It is mandatory for companies importing or distributing medical devices and in-vitro diagnostic devices in Singapore and is required before applying for a Medical Device Dealer’s Licence from HSA.
Although the two frameworks apply to different product categories, both require a structured quality management system. This covers areas such as competent personnel, suitable premises, storage and handling controls, documentation, self-inspections, complaints, recalls and activities performed by external contractors.
Mandatory Compliance vs Voluntary GDP Certificate
Understanding the difference between mandatory GDP compliance and voluntary certification is important before beginning the preparation process.
Mandatory GDP compliance applies to local importers and wholesalers of therapeutic products, Chinese proprietary medicines, CTGTPs and active pharmaceutical ingredients intended for the Singapore market.
Compliance with HSA’s Guidance Notes on Good Distribution Practice is required for local importers and wholesalers dealing with these product categories. HSA conducts GDP audits before issuing the relevant local dealer’s licences.
Voluntary GDP Certificate is a separate certification scheme. HSA offers Good Distribution Practice certification to local dealers of therapeutic products that want formal certification demonstrating conformity with applicable GDP requirements.
Third-party logistics providers, contract warehouses and other distribution operators that do not themselves hold a dealer’s licence may also seek voluntary GDP certification. This can help demonstrate appropriate distribution controls to pharmaceutical principals, supply chain partners and customers.
GDPMDS is mandatory for medical device dealers. Certification to the applicable requirements is a prerequisite for obtaining a Medical Device Dealer’s Licence in Singapore.
Global Quality Services first determines which regulatory track applies to your organisation. This prevents your team from investing time and resources in documentation that does not match the requirements applicable to your products or business activities.

What GDP Certification Covers
HSA’s GDP framework requires your quality system to address nine key areas, which are documented within your Site Master File.
- General information covering your distribution premises, activities, product categories and operational scope
- Personnel covering qualification requirements for key employees, responsibilities, job descriptions and training records
- Premises and facilities covering warehouse design, security, temperature-controlled areas, product segregation and appropriate storage conditions
- Stock handling and stock control covering receipt, storage, picking, packing and dispatch activities
- Documentation covering procedures, records and document control arrangements supporting the quality system
- Product complaints and recalls covering the receipt, investigation, escalation and management of complaints and the execution of product recalls
- Self-inspections covering the internal audit and inspection programme used to monitor continuing GDP compliance
- Contract activities covering GDP responsibilities assigned to contract warehouses, logistics providers and other external parties involved in the distribution chain
A Site Master File generally contains approximately 25 to 30 pages of information and may be submitted to HSA either electronically or in hard-copy format. Global Quality Services helps prepare and structure your Site Master File according to HSA’s applicable requirements and expectations.
A Key 2026 Update: Electronic GDP Certificates
From 30 June 2026, HSA will issue Good Manufacturing Practice Certificates and Good Distribution Practice Certificates as verifiable electronic documents through GovTech’s FileSG digital platform.
The transition to electronic certificates does not change the application procedure, regulatory requirements or applicable fees.
However, organisations that previously maintained physical GDP certificates for customer, principal or supply chain verification should review their document control procedures and ensure their systems recognise the new electronic certificate format.
Global Quality Services helps clients incorporate this change into their document management and compliance procedures as part of ongoing GDP consultancy engagements from 2026 onwards.
HSA GDP Audit and Certificate Details
An HSA GDP certificate is valid for three years from the date of the audit. Companies are advised to apply for a new certificate at least three months before the expected GDP inspection date to provide adequate time for inspection scheduling.
The certificate cannot simply be renewed or re-issued. Once it expires, the company must submit a new application and go through the applicable GDP inspection process again.
After HSA receives a GDP certificate application, the submission is reviewed to determine whether the company is ready for an audit. If significant gaps are identified before the inspection, the audit schedule and, where applicable, dealer’s licence timelines may be affected.
Global Quality Services therefore focuses on getting your documentation, facilities, procedures and quality system audit-ready before the application is submitted rather than waiting for an HSA inspection to identify deficiencies.
Our GDP Certification Consultancy Process for Singapore Companies
Step 1: Scope and track confirmation.
We begin by reviewing your products, activities and distribution model to determine whether your organisation falls under mandatory pharmaceutical GDP, the voluntary GDP certification scheme, GDPMDS, or more than one framework. This establishes the exact scope that needs to be addressed.
Step 2: Gap assessment.
Our consultants assess your existing quality system, warehouse or storage facilities, temperature controls, operational processes and documentation against HSA’s Guidance Notes on Good Distribution Practice or SS 620:2016, where applicable. Findings are documented in a gap assessment report and prioritised according to their potential audit impact.
Step 3: Quality system and Site Master File build.
We develop, revise or align your Site Master File and supporting documentation. This may include standard operating procedures, training records, temperature mapping documentation, complaint and recall procedures, deviation controls, document control processes and the self-inspection programme.
Step 4: Staff training.
Relevant warehouse, distribution and quality personnel are guided through the GDP requirements applicable to your operations. Training focuses on practical areas such as storage conditions, temperature monitoring, record keeping, product handling, deviations and reporting responsibilities.
Step 5: Internal audit and pre-inspection review.
We conduct an internal review that mirrors key aspects of an HSA GDP inspection. Any remaining documentation or operational gaps are identified and addressed before the formal audit.
Step 6: HSA audit support.
We support your team throughout the HSA GDP audit, help coordinate responses to inspector queries and assist with corrective actions where findings are raised. The objective is to ensure that responses are properly documented and submitted within the required timeframe through to certificate issuance.
Benefits of GDP Certification for Singapore Companies
Dealer’s License Without Delays
For pharmaceutical importers and wholesalers, demonstrating GDP compliance is an important part of the HSA licensing process. Having a documented and audit-ready quality system before the inspection can reduce avoidable delays caused by missing records, inadequate procedures or unresolved compliance gaps.
Supply Chain Confidence for Multinational Principals
Singapore-based pharmaceutical and medical device distributors often work with international manufacturers and principals that have strict requirements for their distribution partners. A current HSA GDP certificate or GDPMDS certification provides documented evidence that your distribution activities operate against an established regulatory framework rather than relying solely on internal declarations.
Credibility With Cold-Chain and Logistics Partners
Temperature-sensitive pharmaceutical products require reliable storage, handling and transportation controls. GDP certification can strengthen the credibility of third-party logistics providers, contract warehouses and cold-chain operators when pharmaceutical companies assess potential supply chain partners.
For logistics businesses that do not hold a mandatory dealer’s licence, voluntary GDP certification can provide additional evidence of their commitment to controlled pharmaceutical distribution practices.
Alignment With International GDP Standards
Singapore’s GDP framework is aligned with internationally recognised pharmaceutical distribution principles, including the expectations associated with the PIC/S (Pharmaceutical Inspection Co-operation Scheme) framework. Maintaining a structured GDP system can therefore provide a stronger foundation when working with pharmaceutical organisations and supply chains operating across international markets.
Integration With ISO 9001 and ISO 13485
GDP requirements have considerable overlap with established quality management principles found in ISO 9001:2026 quality management and ISO 13485 medical device quality management. Organisations managing multiple standards can often align areas such as document control, internal audits, corrective actions, training and management review rather than maintaining completely separate systems.

Frequently Asked Questions
Is GDP certification mandatory or voluntary in Singapore?
The requirement depends on the products and activities handled by your organisation. GDP compliance is mandatory for local importers and wholesalers of therapeutic products, Chinese proprietary medicines, CTGTPs and active pharmaceutical ingredients intended for the Singapore market. HSA conducts the applicable GDP audit before issuing dealer’s licences. GDPMDS is mandatory for medical device dealers. HSA also operates a separate voluntary GDP certification scheme for eligible companies seeking formal certification.
What is the difference between pharmaceutical GDP and GDPMDS in Singapore?
Pharmaceutical GDP applies to importers and wholesalers handling therapeutic products, Chinese proprietary medicines, CTGTPs and active pharmaceutical ingredients. It is governed by HSA’s Guidance Notes on Good Distribution Practice. GDPMDS applies to companies importing or distributing medical devices and in-vitro diagnostic devices and is based on Singapore Standard SS 620:2016. Both frameworks are administered by HSA, but their scopes, documentation and audit requirements differ.
How long is a Singapore HSA GDP certificate valid?
An HSA GDP certificate is valid for three years from the date of the audit. It cannot be renewed or re-issued after expiry. Companies must submit a new application and undergo the applicable GDP inspection process when a new certificate is required.
What changed in HSA’s GDP Guidance Notes in December 2023?
The December 2023 revision clarified requirements relating to the distribution and handling of active pharmaceutical ingredients under the Health Products (Active Ingredients) Regulations 2023. Companies importing or wholesaling active pharmaceutical ingredients in Singapore should ensure that their quality systems and distribution procedures address the applicable requirements.
What is the 2026 update to how HSA issues GDP certificates?
From 30 June 2026, HSA is issuing GDP certificates as verifiable electronic documents through GovTech’s FileSG digital platform instead of relying on physical certificates. The change does not alter the application process, regulatory requirements or fees. Organisations should, however, update their document control and certificate verification procedures to reflect the electronic format.
