Marketplaces carry roughly two million Vietnam listings, and none of them can tell you whether the company behind one is a real factory or a trading shell wearing a factory's name. Under the 2026 enforcement regime, a wrong guess carries a 40% penalty. The trust ladder replaces guessing with evidence.
A real factory
A trading shell
A transshipment front
Every tier is built to answer a question you can't answer from a listing:
Is this a real factory, or a trading company, a broker, or a shell? (S1)
Does the production line actually exist, at the address claimed? (S2)
Can it run my spec, at my volume, with the right machines and people? (S3)
Has it really exported, and to whom? (S4)
Will it pass a social or quality audit, and is the paperwork real? (S5)
One question runs alongside all of it: can this supplier prove the product is genuinely made in Vietnam? That one belongs to the Saola Origin badge, covered below.
Six steps, S0 → S5
The Saola trust ladder
Six steps, each one more evidence than the last. A supplier shows exactly the tier its evidence supports, and its entity type is always labeled.
What it means
A basic profile built from public registry data only. Useful as a starting point, explicitly labeled unverified.
Evidence required
Public-registry scrape.
Who collects it
Automated — no human verification yet.
Public registry
What it means
The legal entity is real and identified. We cross-check its tax code (MST) and business registration against national registries, identify the legal representative, and classify the entity as a factory, trading company, hybrid, or broker.
A real person from Saola stood inside the facility. We confirm the address across Vietnam's old and new administrative units and observe production first-hand.
Evidence required
Geo-tagged, timestamped photo/video walkthrough; address confirmation; production activity observed.
Who collects it
A native, Vietnam-based Saola field verifier, on site.
Geo-tagged photo
Timestamped video
Address confirmed
What it means
We've confirmed the factory can actually run your kind of work. We record the machines, capacity, key staff, and quality-control process, and we witness a sample being produced.
Evidence required
Machinery/line inventory; capacity estimate; key staff; QC process observed; sample produced or witnessed.
Who collects it
Saola field verifier (on site) + desk analyst.
Line inventory
Capacity
Sample witnessed
QC observed
What it means
The factory's export history is corroborated from outside its own claims. We cross-reference US bills of lading (public records), call buyer references, confirm with customs brokers, and review certificate-of-origin samples.
Climbing the trust ladder proves a factory is real and capable. The ORIGIN-READY badge answers a different 2026 question: can this supplier prove the product is genuinely made in Vietnam? It is earned separately, from a bill-of-materials input map, a value-add assessment against CBP's substantial-transformation criteria, and photographic process evidence.
What it proves
That a supplier has assembled real, dated, buyer-shareable evidence of where its inputs come from and how much value is added in Vietnam: exactly the evidence a compliance team needs to make a documented decision.
What it does not claim
Saola provides evidence and risk assessment, not a guaranteed customs outcome or a legal origin ruling. We say "verified," "evidence," and "assessment," not "guaranteed" or "certified compliant." The decision, and the ruling, stay with you and your counsel.

Humans at the factory gate
A badge is only as good as the person who earned it. Saola's verifiers are native, Vietnam-based specialists who can walk a production line in Biên Hòa, read a certificate of origin in Vietnamese, and tell a working factory from a staged one. That local presence is the one thing no marketplace or remote AI can copy. As we put it internally:
"AI everywhere inside; humans at the factory gate; evidence in the graph."
It's also what makes the model work. A local field day costs a fraction of a branded audit man-day, which independent firms publicly price around $398, so we collect first-hand evidence at a scale per-event inspection firms can't match. AI handles the translation, extraction, and dossier drafting. The result is evidence-grade verification without audit-firm prices.
Why you can trust the evidence
Relationships open doors in Vietnam, but they never buy a tier. These controls keep the evidence honest.
Verifier rotation
Verifiers are rotated across suppliers so no single relationship owns a record.
No cash, no gifts
Our policy is written and simple: no cash, no gifts, no tricks. Every visit is logged against it.
Hash-stamped raw evidence
Every photo, video, and document is uploaded raw and hash-stamped before any editing — so the original can always be checked.

Random re-verification
A random sample of records is independently re-verified by a second verifier. Discrepancies trigger review, not a quiet edit.
Relationships excluded from scoring
Who introduced whom is logged as a relationship, and deliberately excluded from tier scoring. A family introduction opens a door; it never adds a single tier point.
Your photos and documents stay yours, and are shared only with your consent. Verification opens doors. It never buys a badge.
Evidence has a shelf life, and we honor it
A factory that was real last year might have changed owners, lost a certificate, or moved a line this year. So tiers don't last forever. Field tiers (S2 through S5) are re-verified every 12 to 18 months, and every badge shows the date its evidence was collected. If a tier is overdue, you see that too. Stale evidence is labeled stale, never quietly presented as current.
