Picking a medical packaging supplier is one of those decisions where the easy criteria (price, lead time, location) don't predict the hard outcomes (audit findings, recalls, missed launches). The questions that matter are awkward to ask and the answers are easy to fudge in a marketing deck. Here's how to cut through it.
Question 1: when was the last regulatory inspection
Every contract packer claims to be GMP-certified. Fine, that's table stakes. The real question is when an inspector last walked the floor, what they found, and what got closed.
Ask for the most recent FDA Form 483, EMA inspection report, or local competent authority finding. A clean record over multiple inspections matters more than a current certificate. A supplier who can't or won't share inspection history is telling you something.
Question 2: walk me through your last deviation
Every packaging operation has deviations. The interesting question is how the supplier handles them. Was it caught by the operator or by QC? How fast was it escalated? Did the corrective action stick?
A supplier who can talk through a recent deviation in detail ("the cold seal pressure drifted on Tuesday morning, we caught it in the first ten units, here's what we changed") is telling you the quality system is alive. A supplier who claims to never have deviations is telling you nobody's looking.
Question 3: clinical-to-commercial continuity
If you're spec'ing for a Phase II trial today, you'll want commercial scale-up in two or three years if it works. The packaging line that runs your 5,000 trial wallets needs to run your 5,000,000 commercial wallets without re-validation.
That doesn't happen automatically. Ask the supplier how many of their current commercial customers started as Phase I trial supply. The answer tells you whether they're set up for the long game.
Question 4: technology fit
Cold seal vs heat seal, blister vs wallet, manual vs automated. Different APIs and patient profiles need different approaches. A supplier who insists on one format for everything either has a strong philosophy or a limited factory.
Push them on it. Why this format for my product? What did you consider and reject? The depth of the answer is the depth of the partnership.
Question 5: track record in your therapeutic area
Oncology titration regimens are not the same as cardiovascular daily-dose. Pediatric formulations are not the same as geriatric. Cold-chain biologics are not the same as room-temperature solid orals.
Ask the supplier for examples of customers in your therapeutic area, what they shipped, what challenges came up. Not for the sales reference, for the technical conversation. If they can't talk about your area without checking notes, they're learning on your dime.
Question 6: what's your second-source plan
Single-source pharma packaging is fragile. Hurricane, fire, regulatory shutdown, anything can take a line down for months. A serious supplier has a second-source story, either internal redundancy or a partner network.
Ask. The answer tells you whether they've thought about your supply chain or just their own factory.
How we'd answer these questions
If you're evaluating us, those are the conversations we're happy to have. Drop us a line with your current spec and we'll send you our last inspection report, a recent deviation walkthrough, and three references in your therapeutic area. The right supplier doesn't sell you on certificates, they sell you on the boring details that hold up at 3am during an audit.
