In short: A booth gives you about 15 minutes and no ability to verify anything — so the value is in what you collect, not what you conclude. Run a fixed four-block agenda: identity (manufacturer or trader, factory address, certificate numbers), evidence (a real batch COA, the assay method for your product), commercials (MOQ, lead time, sample policy, Incoterms), and process (can they walk you through a batch record and describe a CAPA process). Photograph every document. Then verify all certificate numbers online within 48 hours and shortlist by evidence, not by impression.
Before the show
Arriving without a prepared specification turns the visit into a series of conversations you cannot compare afterwards. Three preparations change the outcome:
- Shortlist 8–10 suppliers from your own search, using verification signals: certificate numbers you can look up, batch COAs, and a real factory website rather than a directory listing.
- Prepare your specification sheet — product, active marker, method, target price range — and bring samples of competing products if your comparison depends on sensory differences.
- Schedule meetings in advance. Serious manufacturers block time for qualified buyers; walk-ups are handled by whoever happens to be free.
At the booth: the 15-minute evaluation
| Time | Block | What you are establishing | What to collect |
|---|---|---|---|
| Minutes 1–3 | Identity | Manufacturer or trader? Factory location, year established, certificate registration numbers. | Factory address, certificate numbers, business card with a named contact |
| Minutes 3–7 | Product evidence | Whether documents exist for the product you actually want to buy | A real batch COA and the assay method for your product — photographed, including the batch number |
| Minutes 7–12 | Commercials | Whether the terms are workable and internally consistent | MOQ, lead time, sample policy, price bands, Incoterms offered — written down |
| Minutes 12–15 | The tell | Whether they actually run the process they describe | A batch-record traceability walk-through and their CAPA process |
On consistency: the same supplier quoted differently by two people at the same booth is a signal worth recording. Consistency across your notes matters more than a low figure on any single line.
The checklist card
| # | Item to confirm | Why it matters |
|---|---|---|
| 1 | Manufacturer confirmed, with factory address and licence | Determines who you are actually contracting with |
| 2 | Certificate numbers noted (FSSC / ISO / cGMP / HALAL / KOSHER) | So you can verify each one on the issuing body’s database afterwards |
| 3 | Batch-level COA obtained for the target product | A generic template is not evidence for your product |
| 4 | Assay method and minimum specification stated | UV and HPLC results are not interchangeable |
| 5 | MOQ, lead time and sample policy in writing | Verbal figures at a booth rarely survive into the quotation |
| 6 | Heavy-metal and pesticide data policy known | Per-batch or periodic changes your testing cost |
| 7 | Custom specification and packaging flexibility confirmed | Decides whether they can serve your formulation at all |
| 8 | Traceability and CAPA explained | Separates a plant from a trading desk |
| 9 | Follow-up contact and email captured | Without it, the visit produces no verifiable follow-up |
What to do after the show
| Timing | Action | Purpose |
|---|---|---|
| Same day | Photograph and file every document collected, keyed to the supplier name | Booth photographs lose their context faster than you expect |
| Within 48 hours | Send a thank-you with your specification sheet and request batch COA samples | Establishes who responds with documents and who responds with promises |
| Within 48 hours | Verify every certificate number online | A number that cannot be resolved is itself the finding |
| Within one week | Shortlist by evidence and request samples | Converts impressions into comparable, testable materials |
FAQ
How do I tell a manufacturer from a trading company at a booth?
Ask three things: the factory address, the certificate numbers, and whether the facility is owned or contracted. A manufacturer answers directly and can describe the process steps; a trading company tends to answer in terms of “our partners”.
What should I photograph at the booth?
The batch COA for your product — including its batch number and method column — and every certificate with its number, scope and expiry date. Photographs let you verify later; verbal claims cannot be verified at all.
Is it worth visiting a booth without an appointment?
For a first look, yes, but you will usually meet whoever is available rather than the person who knows the technical detail. Schedule in advance for any supplier on your shortlist.
What is the strongest single signal at a booth?
The batch-record traceability walk-through. A manufacturer can describe how a specific lot moved from raw botanical through extraction, drying, testing and packing; a reseller can only describe the certificate.
Should I negotiate price at the show?
Collect price bands rather than negotiating, because you do not yet know the specification the price refers to. Negotiation is productive once quotes share a specification block.
How many suppliers can I realistically evaluate in one day?
At 15 minutes per booth plus travel between halls, a practical ceiling is around 15–20 meaningful conversations. Fewer, with notes taken consistently, beats a longer list of impressions.
What if a supplier cannot provide a batch COA at the booth?
Record it as a gap and follow up in writing. Some manufacturers genuinely cannot print documents on the stand — what matters is whether the document arrives within days of your follow-up, not whether it appears on the spot.
How do I compare suppliers after the show?
Normalise on the same five lines you would use for any quotation: specification, certificate verification, MOQ with batch basis, itemised lead time, and named Incoterm. Anything not recorded in those terms is an impression, not a comparison.
