How to Choose an Autoinjector Manufacturer: The 6 Criteria Sourcing Teams Actually Score
Published 2026-10-27 · Keywords: autoinjector manufacturer
Most autoinjector sourcing projects are decided on six criteria, scored before the first supplier call: freedom to operate, quality system, regulatory support, manufacturing capacity, cost and lead time, and track record. Price is only one input inside the fifth criterion — a supplier who cannot pass the first three will never be audited, no matter what the quotation says.
The six criteria, ranked by how buyers actually weight them
| # | Criterion | What the buyer is really checking | Evidence to request |
|---|---|---|---|
| 1 | IP / freedom to operate (FTO) | Will this design survive a patent review by our legal team? | Own-patent list or design-around statement |
| 2 | Quality system | Is the ISO 13485 certificate real, and does its scope cover finished devices? | Certificate number, issuing body, scope text verbatim |
| 3 | Regulatory support | Can the supplier feed our submission — test reports, DMF-style documentation, MDSAP evidence? | Report list per ISO 11608 part |
| 4 | Manufacturing capacity | Can they hold supply through our launch and ramp? | Cleanroom class, line count, capacity evidence per audit |
| 5 | Cost and lead time | Unit price at volume bands, tooling as a one-time charge, realistic timelines | Written quotation with one-time vs recurring charges separated |
| 6 | Track record | Have they shipped for pharma programs before? | Reference categories, export history (client names stay confidential) |
Criteria 1–3 are pass/fail gates. Criteria 4–6 are scoring inputs. Sourcing teams who invert this order — price first — usually discover at the audit stage that the lowest-priced quotation had no scope coverage and no FTO answer.
What “regulatory support” means in practice
It does not mean the supplier files anything on your behalf. It means the device documentation arrives complete enough to feed your submission: test reports per ISO 11608 part, biocompatibility data per ISO 10993-1, and certificates whose scope you can read in one sitting. Our own manufacturing partner holds ISO 13485:2016 (TÜV SÜD) with the scope text “Design and Development, Production and Distribution of Pen Injector, Disposable Pen Injector” — quoted verbatim because the word finished is what separates useful certificates from decorative ones. MDSAP evidence covering TGA, ANVISA, Health Canada, Japan MHLW/PMDA and USA FDA runs to 2029-02-11.
How to verify a supplier on all six
Ask four questions in one message: which legal entity holds the ISO 13485 certificate and what its scope text says word for word, which ISO 11608 parts are tested and what the report list contains, a one-page FTO or design-around statement, and a written quotation separating one-time from recurring charges. A serious supplier answers in days — and states plainly which documents come at the enquiry stage and which come with the order. A supplier who answers only the price question is telling you which criterion they would fail.
What this does not cover
This article does not cover drug registration pathways, combination-product strategy, or market-specific submissions — those belong to your regulatory team, fed by the device documents above. It also does not compare named competitors; parameter-level comparison belongs in an RFQ, not in marketing copy.
