Third Party vs Contract Manufacturing for Eye Drops: Key Differences (2026 Guide)

If you are a pharma entrepreneur, PCD franchise owner, or marketing company looking to launch eye drops in India, you have likely come across two terms — third party manufacturing and contract manufacturing. Most businesses use them interchangeably. That is a costly mistake.
The model you choose directly affects your production cost, brand ownership, regulatory liability, launch speed, and long-term scalability. Choosing the wrong one — especially in the ophthalmic segment — can delay your market entry by months and create compliance gaps you may not discover until an audit.
This guide breaks down both models specifically for eye drop manufacturing in India, explains what separates them in practice, and helps you decide which one fits your business right now.
What Is Third-Party Eye Drop Manufacturing?
Third-party manufacturing (also called TPM) is a model where a pharma company—typically a startup, PCD business, or regional distributor—outsources the production of eye drops to a licensed manufacturer under its own brand name.
The manufacturer produces the drops, handles the sterile filling, does quality testing, and ships the finished product. You, the brand owner, handle marketing, distribution, and sales. You do not need your own facility, machinery, or manufacturing team.
How it works in practice
You approach a manufacturer like Pushkar Pharma with your brand name and the product list you want—say, Moxifloxacin Eye Drops 0.5%, Carboxymethylcellulose Lubricating Drops, or Ciprofloxacin + Dexamethasone Combination. The manufacturer:
Uses its own approved formulation (or adjusts it to your specification within regulatory limits)
Manufactures under your brand name with your packaging design
Provides all batch records, COA (Certificate of Analysis), and regulatory documentation in your name
Ships the finished, market-ready product to you
You own the brand. The manufacturer owns the factory.
Who is third-party manufacturing best suited for?
First-time pharma entrepreneurs entering the eye care market
PCD franchise companies adding an ophthalmic range
Regional marketing companies expanding their product portfolio
Businesses that want a fast, low-investment entry into the eye drops segment
What Is Contract Manufacturing for Eye Drops?
Contract manufacturing is a more structured, long-term arrangement. Here, a pharma company with its own formulations, regulatory filings, or established product portfolio outsources the actual production work to a manufacturing facility under a formal contract.
Unlike third-party manufacturing, the buyer typically brings their own technical inputs—formulation details, approved drug master files, specific raw material vendors, or unique process requirements.
How it works in practice
You are, say, an established pharma company that has already got CDSCO approval for a new preservative-free eye drop formulation. You have the IP, the dossier, and the regulatory approval — but you do not want to invest ₹8–12 crore in building a sterile ophthalmic unit. You enter a contract manufacturing agreement where:
You supply the approved formulation specifications and drug master file
The manufacturer produces strictly to your technical protocol
Quality control is shared—your QA team may audit each batch
The contract specifies exclusivity, minimum order quantities, pricing, timelines, and IP ownership
You own the product formula. The manufacturer owns the facility and executes production.
Who is contract manufacturing best suited for?
Established pharma companies with proprietary formulations
MNCs or large Indian brands wanting to outsource production without giving up IP
Companies with existing regulatory approvals seeking additional production capacity
Businesses launching novel ophthalmic formulations (preservative-free drops, nano-emulsion eye drops, combination steroid-antibiotics)
Third Party vs Contract Manufacturing for Eye Drops: Side-by-Side Comparison
Why the Distinction Matters More for Eye Drops Than Other Dosage Forms
Eye drops are not ordinary pharmaceutical products. They are sterile, aseptic formulations that go directly into one of the most sensitive organs of the human body. A contaminated eye drop can cause permanent vision damage. This makes the manufacturing model you choose carry significantly higher stakes than, say, a tablet or syrup.
Here is what changes when you are specifically dealing with ophthalmic manufacturing:
1. Sterility requirements are non-negotiable
Both third-party and contract manufacturing for eye drops must happen in a Grade A/B cleanroom environment with aseptic filling lines. Not every manufacturer that handles general pharma is equipped for ophthalmic sterile manufacturing. When evaluating a partner, confirm they have a dedicated ophthalmic unit — not a shared one.
2. Regulatory compliance is stricter
Eye drops fall under Schedule M of the Drugs and Cosmetics Act and require compliance with WHO-GMP or equivalent standards. Under third-party manufacturing, the manufacturer's drug license covers production. Under contract manufacturing, you need to verify how approvals are split — and who bears regulatory liability in case of a recall.
3. Particulate matter, pH, and tonicity testing are critical
Unlike tablets, eye drops require highly specific QC tests — particulate matter analysis, sterility testing, preservative effectiveness testing, pH and osmolality checks. Whichever model you choose, ensure your manufacturer has an in-house QC lab capable of running these tests for each batch.
4. Shelf-life and packaging compatibility
Ophthalmic formulations are sensitive to light, temperature, and packaging material. Plastic LDPE dropper bottles, their seals, and packaging laminates must be compatible with the formulation. In third party manufacturing, the manufacturer typically handles this. In contract manufacturing, you may need to specify your packaging requirements — including any patented dispensing systems.
The Most Common Mistake Pharma Businesses Make
Most businesses entering the eye drops market through third party manufacturing eventually want to switch to contract manufacturing as they scale. The mistake is not planning for this transition from day one.
If you start with a third party arrangement and use the manufacturer's formulations, you do not own those formulations. When you scale up and want to move to a different, larger facility — you cannot take the product with you without re-filing and re-approving.
The smarter approach: Even under third party manufacturing, negotiate clearly about what happens to regulatory documentation, who owns the batch records, and whether you can get a copy of the product's drug dossier. This protects you from being locked into a single manufacturer permanently.
Checklist: How to Choose Between the Two Models
Before you finalise a model, answer these questions:
Choose third-party manufacturing if:
✅ You are launching your ophthalmic range for the first time
✅ You do not have in-house formulation expertise
✅ You need to launch within 60 days
✅ Your initial order volumes are under 10,000 units per SKU
✅ You want to test market reception before scaling
✅ Your budget for manufacturing setup is under ₹20 lakhs
Choose Contract Manufacturing if:
✅ You have your own approved formulations or unique product IP
✅ You are producing more than 50,000 units per SKU per month
✅ You need exclusive production rights for your formulation
✅ You have an existing relationship with a licensed manufacturer and want a formal, binding production agreement
✅ You are planning to export to regulated markets (US FDA, EU GMP)
✅ You are a large pharma company adding ophthalmic capacity without building your own plant

Frequently Asked Questions
Q: Is third-party manufacturing legal for eye drops in India? Yes. Third-party manufacturing for eye drops is fully legal under the Drugs and Cosmetics Act, provided the manufacturer holds a valid manufacturing license under Schedule M and the brand owner holds a valid drug distribution/marketing license.
Q: Can I switch from third-party to contract manufacturing later? Yes, but the transition requires renegotiating agreements and potentially refiling regulatory documents if formulations change. It is advisable to discuss long-term plans with your manufacturer from the beginning.
Q: Does third-party manufacturing compromise on quality? No—provided you choose a WHO-GMP-certified manufacturer with a dedicated ophthalmic unit. The manufacturing standards and QC protocols apply regardless of the business model. What changes is the ownership and commercial arrangement, not the sterility or quality of the product.
Q: What is the minimum order for eye drops under third-party manufacturing? This varies by manufacturer. At Pushkar Pharma, we accommodate small batch sizes to support new market entrants—contact us to discuss your specific requirements.
Q: How long does it take to launch eye drops under the third-party model? Typically 30 to 60 days from finalizing the product list and packaging design, subject to regulatory documentation being in order.
Summary
Third-party manufacturing gives you speed, low investment, and a simple path to launching your own eye drop brand. Contract manufacturing gives you control, customization, and long-term IP ownership. Neither is universally better—the right model depends entirely on where your business is today and where you plan to take it.
For the ophthalmic segment specifically, what matters more than the model is the manufacturer's sterile capabilities, regulatory compliance, and quality standards. A WHO-GMP-certified, dedicated ophthalmic manufacturer protects your brand and your customers' eyesight—regardless of the arrangement you choose.
