Fine Print That Saves: Specs, Hidden Costs, and Liability in Medical Device Manufacturing Contracts

In Part 1 of this series, you learned how to confirm that (1) you have a structured contract and (2) your prospective manufacturer is a qualified medical device partner with the right certifications, experience, and quality framework. 

This article assumes you’ve cleared those basic hurdles and now focuses on the “fine print” inside the contract itself—the detailed terms that will determine your actual costs, your ability to manage quality, and your exposure if something goes wrong.   

Step 3 (Deeper): Locking Down Specs, Quality, and Change Control 

You already know specifications and quality responsibilities matter. Now it’s time to make sure they’re written clearly in your agreement. 

Specifications in the contract 

Your contract should: 

• Include a reference to where the current, controlled specifications (drawings, BOMs, test methods, packaging, labeling) information will be stored and easily referenced. This may be in a quality agreement or some other location where the parties can easily update and reference the specs.  

• Include the correct released part numbers with revisions so they are traceable in the defined engineering control and quality system; and.     

• Reference or identify other documents and how they will be updated. While certain “controlled” documents may not be directly included or attached to the contract, the contract should reference the need for these documents and indicate the process by which they will be stored and updated.  
   

• The goal is that there is never any doubt about which version of the design and manufacturing instructions your contract manufacturer is obligated to use.  

Quality responsibilities and the Quality Agreement 

A Supplier Quality Agreement or Quality Assurance Agreement should work alongside your contract to spell out: 

• Who is responsible for which quality system activities (for example, incoming inspection, in‑process controls, final release, environmental monitoring, complaint data support);  

• How nonconforming product is identified, segregated, investigated, and dispositioned, including who pays for rework, scrap, and additional testing under various scenarios; and 
  

• How audits, inspections, and regulatory requests are handled, including response timelines and what information will be shared. 

Change control in practice 

Your contract and Quality Agreement should also define a clear change-control process, including: 

• Which changes require your prior written approval (for example, critical materials, key suppliers, validated processes, test methods, equipment models, or site changes);  
  

• How changes are evaluated for impact on risk, design control, clinical evidence, and regulatory filings; and 
  

• How changes are documented (for example, engineering change orders, validation reports, updated DMR/DMF), and how you will receive updated documentation. 

This is one of the most important safeguards you have once production is up and running. 

Step 4: What Are the Cost and Supply Chain Exposures? 

Founders often focus on per-unit price and miss the rest of the cost picture. Many of the biggest surprises come from how the contract handles materials, logistics, and “extras.” 

About materials, sourcing, and timelines 

Clarify who is responsible for acquiring materials and components, and on what terms. 

Ask and document where possible: 

• How long it typically takes (“Lead Times”) to source critical materials and what safety stocks or alternative sources exist. Long Lead Times items can easily be identified in the contract to align with financial obligations.  
  

• How the contract allocates risks related to tariffs, customs delays, or sudden price changes (for example, a shipment held at a port with unexpected duties); and 
  

• What timelines or milestones, if any, are provided and what constitutes a missed milestone, what notification is required, and what remedies apply when timelines are missed? 

• How suppliers are approved and managed based on the appropriate approvals and quality requirements needed for your product. 

About subcontractors  

Many contract manufacturers rely on subcontractors for specialized steps or components. 

Your contract should make clear whenever possible: 

• Whether subcontractors can be used or not be used, for which processes, and what qualification criteria apply (for example, requiring ISO 13485 or equivalent controls where appropriate); and who is responsible for managing and paying the subcontracators. 
  

• That your confidentiality and IP protections extend to subcontractors, and that the manufacturer is responsible for ensuring those protections and quality requirements flow down. 

Your contract manufacturer may not always know at the time of contracting which subcontractors will be used, as it may vary depending on the product or project. However, each contract manufacturer should be able to advise what safeguards are in place to protect your confidential information and intellectual property should subcontractors be used, and should be able to agree to disclose the name and location of subcontractors being used so you can accept or reject those services.   Each contract manufacturer should also have a process they can share with or review with you for supplier selection, approvals, qualification and ongoing evaluations.     

Hidden costs no one tells you about 

Several cost categories often surprise first-time innovators: 

Equipment ownership and maintenance 

If specialized equipment is required, determine who purchases it, who owns it, whether it is dedicated to your product, and who is responsible for calibration and preventive maintenance. 

Clarify what happens financially if equipment fails or falls out of calibration and produces nonconforming product (scrap, rework, additional testing). 

Storage and facility costs 

Clarify where materials and finished goods are stored and whether warehousing, controlled-environment storage, or inventory management incur separate fees, especially if you plan batch production or safety stock. 

Regulatory, audit, and recall costs 

Discuss how costs will be allocated if there is a regulatory inspection, audit, field action, or recall, including time spent on investigations, documentation, corrective actions, and potential rework or replacement. 

These details might seem minor during contract negotiations, but they become major issues when you are trying to stay within budget during clinical trials or early commercialization. 

Step 5: Are IP and Liability Really Protecting You? 

Even a solid commercial and quality framework can be undermined if IP and liability clauses are weak or missing. 

About intellectual property and competitors 

Your contract should clearly define: 

• Who owns existing (“background”) IP and any new IP or improvements developed during the relationship; and 

• How confidential information is protected, how long confidentiality obligations last, and whether the manufacturer can work on similar products for direct competitors. 

Many innovators also insist on provisions to ensure that any improvements to the product or process developed by the manufacturer are assigned or licensed back to them on agreed terms. Understanding the distinction between the types of IP and ownership of the IP is important to ensure that each party fully retains the rights to their own information and products.  

Decoding indemnification 

Indemnification, or the requirement that a party compensate another party for harm or loss or secure a party against legal liability, is the epitome of legalese but incredibly important, nonetheless. Indemnification provisions determine which party will be responsible for claims by third parties and defend and compensate the other for certain liabilities. 

Two common scenarios illustrate why this matters: 

• If your device harms someone due to a manufacturing defect or due to the negligence or misconduct of the manufacturer, and the harmed third party sues you, the indemnification clause in your contract may require the manufacturer to defend you and cover associated costs to the extent the issue arose from their performance. 
  

• If your design infringes another company’s IP and they sue the manufacturer, the indemnification clause may require you to defend and indemnify the manufacturer for design-related claims that are due to your infringement. 

In many medical device agreements, indemnification is mutual: you indemnify the manufacturer for claims arising from your behavior, and they indemnify you for theirs. These contractual terms, while often viewed as tedious, can truly help streamline disputes and claims when needed most.  

Contract Language: Vague vs Protective 

The difference between weak and strong contract language often comes down to specificity. 

• Vague formulations like “manufacturer will use reasonable efforts to meet specifications” provide little recourse when product is out of spec or delivery deadlines slip. 
  

• Strong formulations reference specific terms or specifications, define performance standards, and outline concrete remedies such as remaking defective products at no cost within a defined timeframe. 

As you review any contract clause, ask: is it measurable, enforceable, and clear on what happens if the obligation is not met? 

Red Flags: If These Are Missing for Your Medical Device Manufacturing Contract, You May Want to Stop 

Certain elements should appear in every medical device manufacturing arrangement (whether in the main contract, Quality Agreement, or Statement of Work). If you don’t see these addressed, you may want to ask about them or seek additional counsel: 

• Current, controlled product numbers and revision (where available), or specifications, with mechanisms for updates and change control;

• IP ownership, confidentiality, and non-use obligations that protect your proprietary information and limit its use;  

• Warranty language confirming products will be manufactured to defined specifications and outlining applicable remedies; 

• Materials acquisition and sourcing terms, including how pricing, tariffs, and supply interruptions will be handled;

• Defined timelines and milestones whenever possible with provisions for what happens when deadlines cannot be met; 
  

• Subcontractor and supplier controls, including qualification criteria and responsibility for their performance; 
  

• A separate or embedded quality agreement (“QA”) describing quality system responsibilities, audit rights, and regulatory support, consistent with ISO 13485 expectations for outsourced processes; 

• Cost reviews and cadence;

• Shipping terms and conditions;

• Responsibility assignment;

• Forecast terms and allowable changes;

• Invoicing;

• Tooling, fixtures, and asset management; 

• Financial responsibilities for managing materials, excess materials, EOL materials, and approvals required; and

• Order process and timing.

These terms are industry standard and foundational when developing a legitimate medical device manufacturing relationship. 

Key Takeaways 

• Never assume a vendor’s “standard contract” automatically protects your interests; read every section through the lens of responsibilities, quality, cost, IP, and liability; 
  

• Missing core elements like specification controls, IP protection, warranty language, or supplier controls may be deal-breakers for a regulated device; 
  

• Hidden costs around equipment, calibration, storage, tariffs, audits, and recalls frequently catch innovators by surprise—address them explicitly upfront; 
  

• Understanding legal terms (and seeking counsel to assist) like indemnification and ensuring they are balanced can prevent expensive surprises if something goes wrong; and 
  

• A good manufacturing partner will welcome questions and work with you to document responsibilities clearly; reluctance to do so itself may be a signal.

Frequently Asked Questions 

What’s the difference between a Statement of Work and a manufacturing contract? 
A Statement of Work (SOW) is an individual contract, usually governed by a master level agreement or additional terms and conditions that details a specific scope of work, including specific tasks, deliverables, and timelines for a project or phase.  A manufacturing contract or master agreement often covers the broader commercial and legal terms, conditions, and relationship, including liability, IP, warranties, and termination. You generally need both, and each SOW should reference the master or manufacturing agreement and any Quality Agreement so they work together. 

How detailed should specifications be? 
Specifications should be detailed enough that both parties can verify they are working from identical, controlled requirements (for example, drawings, bills of materials, test methods). Typically, these are referenced in an exhibit or controlled document list, with a defined change-control process for updates rather than copying the full specs into the contract body. 

Should I have my own lawyer review a manufacturing contract? 
It is highly recommended that for any medical device manufacturing agreement you seek local counsel to review the terms. The regulatory requirements, product liability exposure, and IP considerations are too significant to leave to chance, and an attorney experienced in life sciences or medtech contracts can often spot issues that non-lawyers miss. 

What if the manufacturer says their standard contract is non-negotiable? 
While some provisions in any contract may be firm, a reputable medical device manufacturer should be able to discuss proposed modifications or revisions to contractual terms to address legitimate concerns around IP protection, quality responsibilities, and liability allocation. If they refuse to discuss any changes at all, reconsider whether this is the right long-term partner.
