Trade shows such as Cosmoprof put hundreds of capsule manufacturers within walking distance of each other. A booth visit gives you a first impression, a few samples, a rough price list. It does not tell you whether a factory can run your formula, hold your fill weight, or ship on schedule for three straight years. The gap between a friendly conversation in Bologna and a dependable production partner is closed by vetting, not by charm.
For brands sourcing single-dose skincare capsules the risk is specific. A soft capsule is a sealed unit: if shell thickness, seam seal, or fill volume drifts, an entire batch fails. Vetting a capsule supplier is therefore less about the sales pitch and more about evidence. What follows is the checklist we suggest to brands that meet manufacturers at shows, covering the documents to request, the areas to inspect, plus how to structure a first order that limits your exposure.
Request Documents Before You Book FlightsA capsule factory that is used to exporting can send a document pack within days. Ask for the quality certificate with its scope, not a logo printed on a banner. Check that the certificate name matches the entity quoting you, since group structures often blur who actually produces.
- Business license with export registration records
- GMP, ISO 22716, or equivalent certificates showing current scope
- Written sourcing statements for gelatin, HPMC, carrier oils
- Recent third-party test reports for heavy metals, microbes, stability
When you visit, walk the production floor rather than the meeting room. Watch how capsules leave the drying tunnel, how operators handle rejects, how the filling line is cleaned between runs. Ask to see the softgel machine that would actually produce your batch, plus the climate control that protects hygroscopic fills.
Pay attention to small signals. Are batch records completed by hand at the end of a shift? Is the quarantine area clearly separated from released stock? Does the warehouse hold ingredients away from light, heat, moisture? These details predict how your product will be treated at scale.
Test the Formula in a Real Sample RunAlways move from free samples to a paid trial batch before signing volume. A lab sample proves a concept, a trial batch proves a process. Request the same fill weight, the same shell material, the same primary packaging you intend to buy.
- Fill weight variation measured across the batch
- Seam integrity after stress, transport vibration
- Organoleptic check for odor, color, leakage
- Accelerated stability at 40C for shell softening, fill separation
Treat the first purchase order as a test of the relationship, not the peak of it. Keep the MOQ modest, agree a written specification sheet, fix the quality criteria before production starts. Ask for pre-shipment photographs, a retained sample, plus the batch record for your file. Then measure the shipment against the specification on arrival and document any deviation in writing.
