GMP vs ISO 13485: Which One Applies to IVD Manufacturers in KSA?

Introduction

When it comes to setting up or operating an In Vitro Diagnostics (IVD) manufacturing facility in Saudi Arabia, a critical question often arises:
Should we follow GMP or ISO 13485? Or both?

Navigating the regulatory expectations of the Saudi Food and Drug Authority (SFDA) requires a deep understanding of both Good Manufacturing Practices (GMP) and the ISO 13485:2016 standard. While the two frameworks share a common goal—ensuring quality and safety—their application and enforcement can vary.

In this article, we break down the key differences, the SFDA’s requirements, and what IVD manufacturers in Saudi Arabia need to prioritize.

What Is ISO 13485:2016?

ISO 13485:2016 is the internationally recognized standard for Quality Management Systems (QMS) specifically designed for the medical device industry. It applies to all aspects of the medical device lifecycle—from design and development to manufacturing, distribution, and post-market activities.

Key principles include:

Risk-based product development and process control
Supplier qualification and traceability
Complaint handling and vigilance
Internal audits, CAPA, and continual improvement
Regulatory documentation and technical files

In Saudi Arabia, ISO 13485 is mandatory for all IVD and medical device manufacturers seeking product registration, factory licensing, and MDMA (Medical Device Marketing Authorization).

What Is GMP?

GMP, or Good Manufacturing Practice, refers to the operational practices and standards that ensure safe, consistent, and high-quality product manufacturing. It focuses primarily on:

Facility hygiene and cleanliness
Trained personnel and standard procedures
Equipment maintenance and validation
Environmental monitoring
Batch documentation and traceability

GMP is often enforced through regulatory inspections, and while it is essential in pharmaceuticals, it is also deeply embedded in medical device manufacturing operations.

SFDA’s Approach: ISO 13485 First, GMP Embedded

In Saudi Arabia, the SFDA aligns with ISO 13485 as the baseline QMS requirement. The authority does not ask for a separate GMP certificate—instead, GMP principles are expected to be integrated within your ISO 13485 system.

This means:

Your QMS must follow ISO 13485 structure and documentation.
Your operations and production controls must meet GMP expectations, such as hygiene, calibration, traceability, and batch records.
SFDA inspections will evaluate both aspects in one audit.

ISO 13485 compliance = GMP compliance, when implemented correctly.

ISO 13485 vs GMP – Comparison Table

Feature	ISO 13485:2016	GMP (Good Manufacturing Practice)
Focus	Full QMS across device lifecycle	Operational controls in manufacturing
Certifiable?	✅ Yes, through notified bodies	❌ No, enforced via inspection only
SFDA requirement for IVDs	✅ Mandatory	🔶 Embedded in ISO 13485 QMS
Covers design controls	✅ Yes	❌ No
Supplier management	✅ Detailed	🔶 General guidance
Documentation	✅ Technical files, SOPs, QMS records	✅ Batch records, logs, validations
Recognized globally	🌍 Yes (especially in EU, MENA, APAC)	🌍 Yes (widely accepted in pharmaceutical/IVD)

Why ISO 13485 Is Crucial for IVD Manufacturers in KSA

Whether you’re manufacturing histopathology reagents, diagnostic kits, or lab solvents, your success in the Saudi market hinges on:

Achieving ISO 13485 certification from an SFDA-approved body
Maintaining a QMS that incorporates GMP best practices
Being audit-ready for SFDA inspections during licensing, MDMA, or renewals

How Mahalil Ensures Compliance

At Company Almahalil Almubtakara for Manufacturing, our facility was built with compliance and quality at the core:

Our team is trained on both ISO 13485 and GMP standards
We operate under a certified QMS, aligned with SFDA guidelines

We continuously train employees on regulatory and safety updates
We conduct regular internal audits, reviews, and CAPA tracking

Our aim is to deliver IVD products that are not only effective and reliable, but also fully compliant with international and national standards.

Conclusion

So, which one applies—GMP or ISO 13485?

Both—but in different ways.
In Saudi Arabia, ISO 13485:2016 is the primary QMS requirement for IVD factories, while GMP is inherently embedded within that framework. Manufacturers must understand and apply both, ensuring that their operations meet SFDA’s expectations at every level.

By aligning your factory with ISO 13485 and implementing GMP-aligned procedures, you will ensure compliance, efficiency, and product quality—setting the foundation for long-term success in the Saudi healthcare market.
