In January 2026 we completed our annual ISO 9001:2015 surveillance audit with zero non-conformities – across raw-material intake, production, laboratory and dispatch. Our certification body’s auditor noted particularly strong performance in batch traceability and corrective-action follow-through.
What the audit covered
- Raw-material intake: Every lithium hydroxide, 12-HSA and base-oil lot checked against spec before release to production. Retention samples kept per lot.
- Production process control: Kettle temperature curves, saponification hold times and milling parameters logged automatically; operators cross-verify.
- Laboratory: Penetration, dropping point, 4-ball EP/wear, oil separation, copper corrosion, oxidation stability – every batch, before release.
- Dispatch and traceability: Every pail, keg and drum carries a batch code linked to the kettle record, the lab COA and the customer order. Retention samples held for 15 months – one year past typical usage.
Why this matters to buyers
An ISO certificate on a wall is easy to fake from a distance; an audit result is not. When you qualify a grease supplier, ask not just “are you certified?” but “show me the last two audit reports, including any non-conformities and their closure.” A clean multi-year surveillance history is one of the few things a trading company cannot simply buy.
Continuous improvement items from this cycle
Zero non-conformities does not mean zero findings. Two minor observations were recorded as improvement opportunities – both around document version control in the lab – and both closed before the audit report was issued. The full report is available to qualified B2B customers on request, as always.
