In short: Vitafoods Asia puts certified manufacturers and trading desks side by side, and the difference is only visible in the answers. Ten questions separate them, and they all reduce to one demand: documents, verifiable on the spot. Ask for the certificate registration numbers, a batch-level COA with its method column, the assay method for your product, and a batch-record walk-through. A manufacturer answers immediately and precisely; a trading desk answers in generalities about partners. Score every supplier on the same table, then verify each certificate number online before you shortlist.

Why preparation matters

Vitafoods Asia brings hundreds of botanical extract suppliers under one roof — from certified manufacturers with in-house laboratories to trading companies reselling third-party material. Both will tell you they are a manufacturer. The only reliable way to tell them apart in a short conversation is to ask for specific, checkable documents and watch how the answers are given.

The ten questions

The ten questions, what a strong answer contains, and what a weak one sounds like
# Question Strong answer Weak answer
1 “Are you the manufacturer, and where is your plant?” Factory location, licence status, and whether the facility is owned or contracted — answered immediately “We have partners” / a regional answer with no address
2 “Can I see the certificate registration numbers now?” FSSC 22000, ISO 22000, cGMP, HALAL, KOSHER or organic numbers produced on the spot for verification Logos on a brochure with no numbers
3 “Do you issue a batch-level COA, and what does it contain?” Batch number, specification, method (HPLC, UV, ICP-MS), results, expiry date and QC signature A generic template with no batch number
4 “What are your assay methods — HPLC, UV or TLC?” “UV, minimum 4.0%” — a method and a minimum, stated together “It’s 4%, no worries”
5 “What is your MOQ, lead time and sample policy?” Written answers: MOQ per product, production lead time, sample cost and lead time Figures that change depending on who you ask
6 “Which certificates are valid for this specific product and this batch?” The certificate whose scope covers the product and site in question A folder of certificates with no scope discussion
7 “Can you customise spec, particle size and packaging?” Specific ranges — mesh size, solubility, fibre drum or pouch with a food-grade liner “Anything you need”
8 “What is your traceability system for a single batch?” A walk-through from raw botanical lot to finished powder, with batch numbers at each step Silence or a vague reference to “full traceability”
9 “How do you handle deviations and complaints?” A described CAPA process and dispute-resolution route “That never happens”
10 “Where can I verify your company and factory?” A verifiable website, a supplier profile, and a physical factory visit Only a directory page

The scoring table

Score each supplier on the same four lines
Dimension Strong Weak Your notes
Manufacturer status Factory address plus certificate numbers “We have partners”
Batch COA Batch number, methods and results present Generic template
Assay method “UV, minimum 4.0%” — method named with the value “It’s 4%, no worries”
Traceability Batch-record walk-through Silence or vagueness

What to bring, and what to collect

Preparation and collection list for the show
Category Items
Bring with you Your specification sheet (product, marker, method), target price bands, a one-page company profile, and business cards for each attendee
Collect from each supplier Batch COA for your target product, certificate numbers, a named contact with a direct email, MOQ and lead-time figures, sample policy
Record consistently The same five data points per supplier, so comparisons are like-for-like rather than impressionistic
Verify afterwards Every certificate number on the issuing body’s database; every claimed website and registration

Turning conversations into a shortlist

Two rules keep the show productive. First, score in the moment rather than afterwards, using the same four lines for every supplier — memory rewrites the weaker conversations within a day. Second, separate what you were told from what you can verify: distribute the certificate numbers to whoever can check them online, and let the verification results, not the booth conversations, determine who receives a sample request.

FAQ

Should I test samples before placing a bulk order?

Yes. Order samples, run identity and assay verification with your own laboratory or a third party, and compare the result against the COA. A sample that reproduces its certificate is the strongest evidence a supplier can give you before production.

What is the most useful question to ask first?

“Are you the manufacturer, and where is your plant?” Everything else depends on the answer. If the reply is vague, the remaining nine questions tell you about a trading relationship rather than a production capability.

Why does the assay method matter so much?

Because a “4% polyphenols” specification measured by UV is not the same product as one measured by HPLC. Without the method, two certificates that appear identical may not be comparable at all — and neither may your own laboratory result.

How do I verify a certificate while at the show?

Record the certificate number and the issuing body, then look the number up on that body’s public database. It usually takes minutes and settles more than any conversation at the booth.

What if a supplier gives different answers to different people on my team?

Record it. Inconsistency between two conversations with the same company is a signal about the reliability of every figure you were given, and it is worth more than the price difference between quotes.

Do I need an appointment to have a useful conversation?

Appointments improve it, because you meet the person who knows the technical detail rather than whoever is available. Walk-ups are still worth doing at the start of the show to build your shortlist.

What should I do in the 48 hours after the show?

Send a follow-up with your specification sheet and a request for batch COA samples, and verify every certificate number you collected. The suppliers who respond with documents become your shortlist; those who respond with promises do not.

Can I negotiate MOQ or pricing at the show?

Collect bands rather than negotiating, because at that point you do not know the specification behind the figure. Negotiation becomes meaningful once quotes share a common specification block.
