Choosing a sterile-liquid contract manufacturer in India: a 10-point checklist

Outsourcing sterile liquids is a different exercise from outsourcing tablets. The product is only as safe as the site's water, air and filtration — none of which show up on a price sheet. Use this checklist when you shortlist a pharmaceutical contract manufacturer in India for SWFI, saline, respules or FFS ampoules.

1. Water systems. Ask for the Purified Water and WFI schematics, the storage temperature and the loop sampling plan. Hot storage at 80 °C and above with routine conductivity, pH, endotoxin and microbial testing is the benchmark.
2. Filling technology. Confirm the products will be made on Form-Fill-Seal lines, not re-packed from bulk.
3. Segregated flows. Separate entries for personnel and materials, and a separate area for suspensions, prevent cross-contamination by design.
4. Batch size range. A 500–2,500 L range covers both launch quantities and tender volumes without changing sites.
5. Sterilisation routes. Autoclaving, filtration and SIP should all be validated, with online filter integrity testing documented on every batch.
6. In-house QC. Wet, instrument and micro labs on site — with HPLC, UV and IR — shorten release times and keep the data under one quality system.
7. Stability programme. ICH-compliant stability studies for your target markets, ideally already under way for the presentation you need.
8. Warehouse discipline. Controlled storage, sampling and RLAF dispensing booths, and FEFO/FIFO practice.
9. Utilities headroom. Installed power, generator backup, chilling, compressed air and boiler capacity tell you whether the site can absorb your volumes.
10. Leadership and organisation. A clear organogram with named heads of Operations, QA, QC, Engineering and HR is a sign the quality system has owners.
