A customer or certification audit that touches reusable containers asks a fairly predictable set of questions. They are not difficult and they are not adversarial – the auditor needs evidence that the packaging is controlled rather than unmanaged. Where the answers are on file, the review is short. Where they have to be assembled, it is not.
What is it made of
A material declaration for the container: the polymer, any additives, and any relevant compliance statements such as food-contact status. That is a document the container supplier should provide, and it is worth requesting with the first order rather than at the first audit. Where the material is unknown, the audit stops there.
How is it cleaned, and how do you know
The cleaning procedure, the frequency, the record for a specific period, and the verification results. Those are the four things described in hygiene records for reusable containers, and they are the most common source of findings – usually because the record exists but the verification does not.
How do you know a container is fit to use
A retirement criterion, an inspection process, and a record of inspections. Where a fleet has no criterion, the answer is that someone decides, which is not an answer an auditor can accept. A documented criterion with measurements that anyone can apply is a short document and it closes the question.
Can you trace a container
Identification, and a record linking containers to what they carried. The depth required varies by application – batch level is enough for most, unit level for some. Where a fleet has no identification at all, this question cannot be answered and the finding is significant. The numbering question is covered in what a container number should carry.
What happens to containers at end of life
A route, a recycler, or a documented disposition. Where containers are simply discarded, that is an answer and usually a poor one. Where they are recycled, the route and any documentation from the recycler is the evidence. The options are set out in what happens to a container at end of life.
What the auditor does not ask
About the mechanical performance of the container, unless the application makes it a safety question. About the supplier’s manufacturing process, unless there is a specific certification requirement. And about cost. The scope is narrower than people expect, and preparing for it is a matter of having six documents rather than a large system.
Preparing in advance
Put the six answers in one folder: material declaration, cleaning procedure, cleaning records with verification, retirement criterion, identification scheme, end-of-life route. Where those six exist, an audit of the packaging is a short conversation. Where they have to be created during the audit, it is not.
What happens when one answer is missing
A single missing document does not usually fail an audit – it becomes a corrective action with a deadline. The cost is the time spent closing it, and the risk is that the same gap is found again next year because the underlying process was never put in place. Closing a finding properly means creating the thing that was missing rather than producing a document for the occasion.
Where several answers are missing, the auditor will reasonably conclude that the fleet is unmanaged, and the scope of the finding widens from documentation to process. That is a much larger piece of work, and it is why assembling the six documents before the first audit is worth doing rather than after the first finding.
Reviewing annually
Check that the documents still describe what actually happens. A procedure that was written once and has drifted is worse than none, because the auditor will test it against practice and find the gap. An annual review, done by whoever runs the fleet, is fifteen minutes and prevents that.
