Pharmaceutical packaging is a complex and strategically significant step in the supply chain. Here’s what you need to know, and the questions you should be asking before you outsource it.
Getting the right product to the right patient at the right time sounds straightforward. In practice, it depends on one of the most underestimated steps in the entire pharmaceutical supply chain: packaging.
For much of its history, pharmaceutical packaging was treated as a commodity. A necessary cost at the end of the manufacturing process, something to be optimized for price and standardized wherever possible. That approach no longer works.
Today, packaging sits at the intersection of regulatory compliance, patient safety, supply chain complexity, and commercial strategy. The companies that still treat it as an afterthought tend to find out the hard way.
This article covers what contract packaging is, why it has become more complex, and what questions to ask before choosing a partner.
What is contract packaging in pharma?
Contract packaging is the outsourcing of pharmaceutical packaging operations to a specialist third-party organization. Rather than building their own packaging infrastructure — equipment, cleanrooms, qualified personnel, regulatory expertise — pharmaceutical and biotech companies engage a contract packaging organization (CPO) to handle some or all of their packaging needs.
Scope varies widely. At its simplest, it covers primary packaging: the container in direct contact with the drug product, whether that’s a blister pack, vial, pre-filled syringe, or bottle. Secondary packaging — the outer carton, labeling, leaflets, and patient-facing components — is typically included as well. More comprehensive arrangements extend to serialization and track-and-trace, kitting and assembly of combination products, and in some cases full supply chain management from manufacturing site to market.
A specialist contract packager also handles the regulatory and quality infrastructure surrounding the packaging itself: batch release documentation, qualified person (QP) release, importation testing for products entering regulated markets, and compliance obligations across multiple jurisdictions.
Why packaging has become more complex
The contract packaging industry has shifted substantially over the past decade. A defining change is the move from high-volume, standardized production toward personalized medicine — smaller batch sizes, bespoke formats, and products designed for specific patient populations.
“The role of contract packaging changed a lot in the last couple of years, moving from a standardized, more generic approach to personalized medicine, where batch sizes have decreased a lot, where the need for tailor-made custom solutions has increased a lot.”
Pieter Cervruysse, VP Customer Success & Supply Chain, Tjoapack
Several forces are converging to drive that complexity. Specialty pharma and orphan drugs require packaging solutions that standard production lines cannot accommodate. Injectables and combination products — pre-filled syringes, autoinjectors, self-administration devices — demand precision assembly and tightly controlled environments. Products launching across multiple markets must simultaneously satisfy different serialization formats, language requirements, and importation testing obligations.
Serialization requirements now mandate unique product identification in the EU, US, and other major markets. And supply chains have grown more geographically complex: APIs and drug products are increasingly manufactured in lower-cost regions, creating importation and testing obligations for companies selling into Europe and elsewhere.
“Currently, there’s a really big cost pressure with regard to the cost per pack. That also ultimately drives a very complex supply chain — where is the API coming from? Most companies are also trying to move manufacturing of the drug products to lower-cost countries, so that makes the supply chain process very difficult.”
Kun Shing Chan, Director Quality, Tjoapack
The environmental controls required for pharmaceutical packaging add a further layer of complexity. Primary packaging operations — those in direct contact with the drug product — typically require ISO 7/ISO 8 (EU GMP Grade C/D) cleanroom conditions. Not all packaging organizations are equipped to meet these standards consistently across varying batch sizes and product types.
Why companies outsource packaging
Few pharmaceutical companies — even large ones — have the internal capability to keep pace with the full range of modern packaging requirements. The equipment investment, multi-market regulatory expertise, qualified personnel, and operational flexibility required to handle variable batch sizes and formats represent a substantial overhead. For most companies, that capital is better deployed in drug development.
For smaller biotech and specialty pharma companies, the case is clearer still. A specialist contract packager provides established systems, qualified teams, and market-specific knowledge from day one, without the build-out cost.
For larger companies with some internal capacity, a specialist partner adds value in areas of high complexity: combination products, serialization across multiple markets, cold chain requirements, or markets with particularly demanding importation obligations.
What distinguishes a specialist contract packager from a generalist or large integrated manufacturer is focus. Packaging is the core service — not one step in a longer manufacturing chain. That focus translates into equipment investment tailored to packaging, regulatory teams whose day-to-day work is batch release and importation compliance, and account teams with the bandwidth to work closely with clients through complex, non-standard projects.
Are you asking the right questions?
Understanding what contract packaging involves is only the first step. The harder question — and one that many companies underinvest in — is whether they approach a packaging partner with the right level of preparation.
What experienced packaging teams see consistently is that the solution a company ends up with rarely matches what was requested at the start. That’s not a failure of competence on either side. It reflects the genuine complexity of modern pharmaceutical packaging and the fact that most companies begin the process when they already have a problem to solve or a deadline to hit.
“What we often see is that the final solution that we come up with is not the one that the customer asked for in the beginning. The scoping, the feasibility — what are you actually looking for? Having that initial talk is really important.”
Pieter Cervruysse, VP Customer Success & Supply Chain, Tjoapack
That urgency compresses the discovery process in ways that create downstream pain: misaligned specifications, regulatory delays, or formats that work in principle but not in practice for the patient.
The companies that navigate this well treat partner selection as a strategic process, not a procurement exercise. They arrive with clarity on what they need, what constraints they’re working within, and what a successful outcome looks like for the patient.
Five questions to ask before you choose a contract packager
Before you go to market, make sure you can answer these:
1. What do you actually need — and have you separated what you want from what is genuinely feasible?
Many companies arrive with a brief built around internal assumptions rather than external realities. Packaging format, batch size, timeline, and regulatory obligations all interact in ways that may not be obvious until a specialist reviews them. A good packaging partner will challenge the brief early and offer alternatives where needed. If they don’t, that’s a signal.
2. What does the patient journey look like, and how does your packaging affect it?
Packaging decisions have direct implications for patient adherence, administration safety, and clinical outcomes. Self-administration devices, formats designed for use outside clinical settings, and combination products all require packaging that has been engineered around the patient’s experience, not just the product specification.
3. What are your regulatory obligations in each target market?
Importation testing, QP release, serialization compliance, and labeling requirements vary significantly across markets. The EU, US, and other regulated markets each carry specific obligations that affect how and where packaging can be carried out. Your packaging partner needs to understand these requirements in detail — not just their own step in the process — and have the qualified teams and documentation to deliver on them.
4. Where is your drug product manufactured, and what supply chain complexity does that create?
If your API originates in Asia and your target market is the EU, your packaging partner will need to manage importation testing and supply chain coordination across significant geographic distance. That’s a common scenario today — but not every packaging organization handles it with equal capability. Ask specifically about experience with third-country imports and the internal processes they use to manage them.
5. Can this partner support you end-to-end — from manufacturing site to market release?
A packaging partner that understands only their own step in the process will always be limited in the value they can add.
“Can we fulfill their requirements, can we assist them from beginning until end — until the product comes to us, until the product hits the patients at hospitals with the treatments?”
Diana Orozco, Team Leader Customer Success, Tjoapack
Look for teams with the regulatory capability, documentation infrastructure, and account continuity to take a product from intake through to market release. Named customer success contacts, proactive communication, and clearly defined escalation paths matter as much as technical capability when projects get complex.
The value of getting this right
Pharmaceutical packaging has evolved from a commodity service into a strategic capability. The partners that recognize this — and invest accordingly in scoping, feasibility, and the selection process — deliver real advantages: faster time to market, cleaner regulatory pathways, lower cost of complexity, and better patient outcomes.
The right contract packager thinks beyond their own step in the process. They identify feasibility issues before they become timeline problems, understand your regulatory obligations as well as their own, and tell you clearly when something isn’t achievable in the requested format or timeframe.
For companies working with specialized products, smaller batch sizes, or complex multi-market launches, finding a partner with that combination of expertise, flexibility, and transparency is the difference between packaging that supports your supply chain and packaging that creates friction in it.
