Contract Manufacturing of Medical Devices: Through a Quality and Regulatory Lens

Given the rapid advancements in technology and evolving clinical needs, the medical device landscape is shifting fast and so are manufacturing workflows and regulatory overheads. For high-risk medical devices, companies increasingly rely on contract manufacturing partners to manage operations that are too complex or costly to run in-house. While cost is a sizeable factor, stronger motivations are access to scale, specialized capabilities, and faster execution. That said, one principle remains unchanged: production may be outsourced, but the responsibility for regulatory compliance always rests with the Original Equipment Manufacturer (OEM). 

For quality assurance and regulatory affairs (QARA) leaders, managing global supply chains now requires closer and continuous monitoring of external partners and clearer evidence that every site meets regulatory expectations. Launching in multiple markets further increases this compliance overhead. 

Every regulator expects end-to-end oversight, and non-compliance costs money, time and credibility. Yet, many MedTech leaders make the error of approaching contract manufacturing as a procurement activity, rather than a regulatory responsibility. On the contrary, they must implement an outsourcing model built for regulatory and market success, and this article outlines a practical framework to achieve this. 

Factors Driving Adoption of Contract Manufacturing in MedTech:

• Scalability and Cost Efficiency: Global CMOs can deliver medical devices at scale, reducing CAPEX and lead times.

• Specialized Capabilities: From cleanroom molding to sterilization, CMOs often bring niche technical expertise for complex medical devices.

• Post-COVID Supply Chain Reset: The coronavirus disease 2019 (COVID-19) pandemic exposed internal bottlenecks and sparked a shift toward more flexible, diversified manufacturing ecosystems. 

Driven by innovation in Class II / III devices and increased outsourcing of specialized processes, the global medical device contract manufacturing market is growing rapidly. Currently expanding at a CAGR of 10.9%, the market is expected to reach USD 140.8 billion by 2030. 

To stay competitive, medical device companies must embrace this trend without compromising on regulatory compliance. 

Class I, II, III Devices: How Do QARA Responsibilities Change When You Outsource? 

Class-I Devices: Low Risk → Basic Supervision Class-I devices (e.g., bandages, manual instruments) are low risk and typically subject to general controls.  QARA focus: Ensure contract manufacturers comply with foundational quality requirements like 21 CFR Part 820 (U.S.) or ISO 13485 (EU). Most are exempt from 510(k) pre-market notification in the U.S., but EU Medical Device Regulation (MDR) now requires CE marking and quality management system (QMS) compliance for some low-risk devices as well.  Formalize responsibilities through supplier agreements and periodic quality audits.

Class-II Devices: Moderate Risk → Stronger Controls Devices like infusion pumps or diagnostic tools fall under Class II and require more regulatory documentation.  QARA focus: Support 510(k) submissions (U.S.) and technical documentation (EU). Outsourced partners must follow design controls and verification protocols, especially if they’re involved in development.  Implement clear traceability for validation and integrate external partners into risk and design reviews.

Class-III Devices: High Risk → Intensive Scrutiny These include implants and life-supporting devices, requiring relevant clinical evidence and post-market monitoring.  QARA focus: Maintain comprehensive design history, clinical data, and risk management files. Manufacturers must ensure outsourced partners are always prepared for regulatory audits and aligned on vigilance, unique device identification (UDI), and MDR / FDA compliance.  Conduct frequent audits and embed contract manufacturers into your QMS and post-market surveillance (PMS) systems.

OEM vs. Contract Manufacturer: Defining Quality and Regulatory Ownership

Original equipment manufacturers (OEMs) are always the legal manufacturers. This means: 

• You’re liable for the safety, efficacy, and compliance of your device.
• Regulatory bodies will hold you accountable for quality failures, even if they happen at your CMO.

Contract manufacturers, on the other hand: 

• Must be ISO 13485:2016 certified to comply with regulatory expectations across most regions.
• Must maintain validated processes, keep the Device History Record (DHR) up-to-date, and stay prepared for audits at all times. 
• Quality agreements must clearly assign responsibility for: 
  • Handling complaints 
  • Escalating issues to regulators 
  • Managing change control, maintaining risk files, completing CAPA activities, and ensuring labelling compliance

Critical QARA Risks in Outsourced Manufacturing

Risk Area	Impact
Regulatory non-compliance	Delays, warning letters, denied approvals
Inadequate supplier oversight	Form 483s, consent decrees
Incomplete documentation	Delays in Notified Body / FDA / National Medical Products Administration (NMPA) reviews
Siloed CAPA and change control	Quality drift, device recalls
Missed clinical planning	Duplicate studies, increased cost and time
Language / localization gaps	Submission rejections or market delays
Intellectual property (IP) exposure	Risk of competitive leakage

Real-World Case Study: FDA Warning Letter Triggered by Lapses in Supplier Control

In September 2025, a U.S. medical-device company received an FDA Warning Letter after inspectors found major gaps in its supervision of a contract design manufacturer. The supplier could not produce required design documentation, had introduced unapproved changes to the device, and lacked evidence of proper validation. FDA concluded that the OEM had not exercised adequate purchasing controls or supplier monitoring.

The company was required to stop distribution of the affected devices, rebuild the design records with its supplier, and revise its supplier-control processes.

Lesson: Even when the lapse occurs at a third-party site, the OEM carries full responsibility. Weak supplier controls can lead to halted distribution, remediation costs, and regulatory scrutiny.

Region-Specific Regulatory Expectations from Medical Device Companies and Their CMOs 

Outsourcing doesn’t relieve you from regulatory scrutiny. It comes with complete accountability despite shared execution. Regulatory authorities in major markets expect OEMs to enforce supplier controls, submit region-specific documentation, and validate that every contract site is compliant. 

Key considerations for you and your CMO across major markets include: 

United States – FDA  

• Framework: Quality System Regulation (21 CFR Part 820). 

• Expectation: OEM must validate and monitor all outsourced manufacturing per 21 CFR 820.50 (purchasing controls). 

• Risk Note: FDA warning letters frequently cite inadequate supplier supervision as a top violation. 

European Union – EU MDR  

• Framework: Medical Device Regulation (EU) 2017/745. 

• Expectation: OEM retains the responsibility even when outsourcing. CMOs must be identified as “critical subcontractors”. 

• Key Risk: Unannounced audits are permitted. OEMs must demonstrate control over the entire supply chain. 

• Documentation: Quality Agreements, PMS plans, and technical documentation must reflect subcontractor controls. 

United Kingdom – Medicines and Healthcare products Regulatory Agency (MHRA)  

• Framework: Medical Devices Regulations 2002 (UK MDR 2002), as amended in 2025.  

• Expectation: OEMs outside the UK must appoint a UK Responsible Person (UKRP). CMO oversight must be documented. 

• Coming Change: Expect a gradual shift to UKCA-specific submission requirements, while CE-marked medical devices remain accepted in Great Britain under extended transitions until 30 June 2030 (depending on device type and certification status). 

India – Central Drugs Standard Control Organization (CDSCO)  

• Framework: Medical Device Rules (MDR), 2017. 

• Expectation: All device classes (A–D) require registration or licensing. OEM must file the Plant Master File (PMF) and the Device Master File (DMF). 

• Representation: Foreign OEMs must appoint an Indian Authorized Agent (IAA). 

• Inspection Focus: CMO licensing, QMS verification, and product-specific testing are common CDSCO checkpoints. 

Japan – Pharmaceuticals and Medical Devices Agency (PMDA)  

• Framework: Pharmaceuticals and Medical Devices Act (PMD Act) and QMS Ordinance No. 169. 

• Expectation: Class II–IV devices require pre-market approval (Shonin) and must be manufactured by a foreign manufacturer establishment (FME). 

• Representation: Foreign OEMs must appoint a Marketing Authorization Holder (MAH). 

• Documentation: Japanese Industrial Standards (JIS) compliance, local test data, and Japanese-language submissions are mandatory. 

Australia – Therapeutic Goods Administration (TGA) 

• Framework: Therapeutic Goods (Medical Devices) Regulations (TGA) 2002. 

• Expectation: OEMs must submit an Australian Register of Therapeutic Goods (ARTG) application with proof of QMS and product conformity. 

• Shortcut: TGA recognizes CE marking and Medical Device Single Audit Program (MDSAP) audits to streamline conformity assessment. 

• Risk Note: TGA often verifies QMS robustness and documentation traceability for high-risk devices. 

Key Takeaway 

Regulators in every region look for clear proof that the manufacturer has control over its processes and suppliers. They also check whether the organization can handle audits and meet the specific requirements of each market. Your QMS needs to support these expectations across regions, and your contract manufacturer must be prepared for inspections at any time.
