Choosing a contract manufacturer on price alone is how brands end up with thin extract loads, missed seasons and labels they have to reprint. This page sets out the questions that actually distinguish a good manufacturer from a cheap one, including several that are uncomfortable for us to answer, which is rather the point.
Questions about quality
Which ingredients do you re-test in house rather than accepting the supplier certificate, and why those? What happened with your most recent failed batch? Can I see a completed batch record and follow one product through it? Where does raw material sit between arrival and acceptance?
These four questions are hard to answer convincingly if the underlying practice is not there. A manufacturer who answers them specifically is telling you a great deal more than one who shows you a certificate.
Questions about the composition
Will you give me a per-unit composition sheet with quantities before I order? What standardisation percentage is the extract, and will the certificate of analysis report it? If a commodity price rises, do you reprice or reduce the extract load?
That last question matters more than it sounds. Holding a price by quietly cutting actives is common in this industry and invisible without testing. Ask it directly and listen to how the answer is phrased.
Questions about claims
Will you manufacture against any artwork I send you? Do you review labels for claims before plates are made? Would you refuse an order over wording?
A manufacturer who will print anything is not being accommodating; they are transferring a risk to you while taking your money. Under Indian law you carry the consequences of what the label claims, not them.
Questions about delivery
What is the realistic lead time, from what starting point? What most commonly delays orders? If I come to you too late for a season, will you tell me?
The honest answer to the last one is revealing. A manufacturer who takes a joint-care order in December knowing you will be selling into February is prioritising their order book over your business.
And the obvious one: can I visit?
Ask to see the plant. In an industry where certification logos are easy to display and hard to verify, willingness to be inspected is the most credible quality signal available. If a manufacturer is reluctant, treat that as information.
Bring an auditor if you are placing significant volume. Any manufacturer who objects to a client audit is telling you something you need to know.
