Supplier verification services split into five categories, and each answers a different question. Inspection and factory audits tell you a plant exists and how it runs. Registry and KYB checks confirm the legal entity. Sanctions screening tells you whether you may trade with it at all. Trade-record verification shows whether the company actually ships, to whom and how recently. Credit reports estimate whether it will still be solvent at delivery. The expensive mistake is buying one and assuming it covered the rest.
The short version
- Inspection and audit, registry / KYB, sanctions screening, trade records, credit reports. Complements, not competitors.
- Run the free checks first. Registry lookups, sanctions screening and a basic trade-record check cost little or nothing, and can end the deal before you pay an audit fee.
- Pay for fieldwork when the goods are the risk. Audits and pre-shipment inspection are priced per visit or per man-day, by firms such as SGS, Bureau Veritas, the TÜV bodies, Intertek and QIMA.
- Match depth to exposure. A $4,000 trial order and a $250,000 private-label programme do not deserve the same budget.
- No single service proves a supplier is safe. Each closes one gap.
What do supplier verification services actually do?
They independently test a claim the supplier has made about itself: that it exists, that it is registered at that address, that it is not sanctioned, that it can manufacture what it advertises, that it exports, or that it pays its bills. Each type verifies one claim, not all of them.
That is where money goes missing: a genuine audit report on a genuine factory, and the deposit wired to a different entity with no shipping history at all.
The five kinds of supplier verification services, compared
Compare cost shape rather than headline price. Fieldwork is quoted per visit; screening is either free or a subscription.
| Category | Question it answers | Typical cost shape | Use it when |
|---|---|---|---|
| Physical inspection and factory audit | Does the factory exist, and can it make this to standard? | Fee per visit or per man-day, quoted on scope, product and location. Usually the largest item. | Order value justifies sending a person; first production run; safety or labour risk. |
| Company registry / KYB | A real, currently registered entity, at this address, with these directors? | Free to low. Official registers are mostly free; certified extracts and KYB platforms charge per check or subscription. | Every counterparty, before the first payment. |
| Sanctions and denied-party screening | Am I legally allowed to trade with this party? | Free for one-off government-list lookups; subscription for automated screening and monitoring. | Every counterparty, again at renewal. Mandatory with US, EU or UK exposure. |
| Trade-record verification | Does this company actually export, to whom, how often, how recently? | Free basic check; subscription or per report for shipment-level depth. | Before any deposit; when a trader presents itself as a manufacturer. |
| Credit report | Will it still be trading at delivery? | Per report or subscription. Richest where audited accounts are filed publicly. | Long lead times, large deposits, tooling money, credit terms. |
What each category proves, and where it stops
Physical inspection and factory audits
This is where the large testing, inspection and certification firms operate: SGS, Bureau Veritas, the TÜV bodies (TÜV SÜD, TÜV Rheinland), Intertek and QIMA, plus many regional firms. The menu is broadly standard. Factory audit of the site and quality system. Social compliance audit against a scheme such as Sedex SMETA or amfori BSCI. Pre-production, during-production and pre-shipment inspection, sampled to an acceptance quality limit under ISO 2859-1. Container loading supervision. Lab testing to the destination standard.
Supplier audit services prove the address is a working plant and that sampled goods met specification on the day. They do not prove the company exports anything, or that the audited entity is the entity on your invoice. Marketplace badges are a variant: Alibaba's Verified Supplier tier is a paid membership level assessed by SGS and TÜV Rheinland against more than 100 items across eight categories. Real fieldwork, but supplier-initiated and paid for, so no badge means little.
Company registry and KYB verification
Most of this you can do yourself, free. UK entities sit on Companies House with filings and officers. Chinese business licences carry an 18-digit unified social credit code, checkable against the national enterprise credit publicity system. Indian exporters hold a 10-digit Importer-Exporter Code, and DGFT's public View Any IEC lookup returns the holder's name, registered address, date of issue and current status. A 9-digit D-U-N-S number identifies an entity but verifies nothing by itself.
Registry work proves the entity is real, current and matches what you were told. It cannot prove the company trades, owns a factory, or has money. The check that earns its keep is a three-way match: name on the proforma invoice, name on the bank details, registry record. A mismatch across those three is the most reliable early signal of payment diversion.
Sanctions and denied-party screening
Free government tools cover the basics. OFAC's Sanctions List Search covers the SDN list and its non-SDN companions. The US Consolidated Screening List combines restricted-party lists from Commerce, State and Treasury, including the Denied Persons List, Entity List, Unverified List and Military End User List, with free search and a public API. The EU, UK OFSI and UN lists cover the other main regimes.
Paid vendors sell matching and monitoring rather than access: fuzzy names, aliases, beneficial owners, vessels, and an alert when a counterparty cleared last year is listed this year. Screening confirms legal permissibility on the day you ran it, nothing about competence.
Trade-record verification
This answers what the others structurally cannot: does the company actually ship, and who buys? The evidence is shipment-level, from bill of lading and manifest records rather than paperwork the supplier hands you.
In the United States, inward vessel manifest information is obtainable from CBP under published rules, which is why so much bill-of-lading data circulates commercially on US lanes. One caveat vendors rarely volunteer: a US importer can request confidential treatment of its name and address, effective two years across all ports, so an absent name does not prove inactivity. For Indian exporters, TradeVerify works from mirrored licensed trade data.
Read four things: how many distinct counterparties, which destination markets, how recent the last shipment is, and whether volume is rising or has quietly stopped. Consistency with the claimed product matters as much as volume. A trade record says nothing about quality, factory ownership or working conditions.
An audit proves a factory exists and how it operates. A trade record proves whether goods actually leave the country, and who buys them. Neither substitutes for the other, and most sourcing disasters happen in the gap between them.
Credit reports
Dun & Bradstreet, Creditsafe, Coface, Allianz Trade and local bureaus sell credit files: payment behaviour, legal filings, group structure, financials where publicly filed. Worth buying when you fund tooling or pay a large deposit against a long lead time.
Coverage depth is the limit. Many privately held exporters file no audited accounts, so the file is thin, modelled, or built from the company's own submissions. Pair the financial question with payment structure: a telegraphic transfer deposit is unsecured, a letter of credit pays against documents. Fix your Incoterms and require the bill of lading, commercial invoice, packing list and certificate of origin at presentation.
Match verification depth to order value and risk
- Sample or low-value trial order. Registry lookup, sanctions screening, free trade-record check. Spend nothing.
- First production order. Add a paid shipment-history report and confirm the paying entity matches the registered entity. Add pre-shipment inspection if defects would be hard to prove on arrival.
- Repeat programme, private label or OEM tooling. Factory audit from an accredited firm, inspection per shipment, credit report if you are funding moulds.
- Regulated goods (food, electrical, toys, cosmetics, medical). Lab testing to the destination standard is a separate purchase, and not optional.
- Ongoing relationship. Re-screen sanctions on a schedule, watch the trade record for a collapse in shipping activity, re-audit periodically.
Sequence matters as much as budget. The free checks take an afternoon, and sometimes end the conversation.
How to choose a supplier verification company
Third party supplier verification is worth the fee only if the third party is independent of the supplier, and covers your country, product and language. Five questions most supplier verification services will answer by email:
- Who performs the work, and is the inspection body accredited to ISO/IEC 17020?
- Is fieldwork subcontracted, and to whom?
- What is the deliverable: photo report, scored report, pass/fail certificate, raw records?
- Who pays for the assessment? A badge a supplier buys for itself partly measures willingness to pay. That includes our verified supplier badge, which is why scoring never moves with it.
- Can you read a full sample verification report before you commit?
How TradeVerify helps
TradeVerify covers one category: trade-record verification. It is the cheap gate before you spend on fieldwork.
- Check the exporter by name. The free check tells you whether shipment records exist for that company, across 15.7M+ companies in 240+ markets.
- Read the TradeScore inputs, not only the number: export history, distinct buyers, destination markets, activity recency, shipment trend, red-flag screens.
- Compare the record with the pitch. Ten years of European exports in the deck, two shipments to one buyer in the record: ask about it before the deposit leaves.
- Escalate deliberately. If the record holds and the order is large, that is the point to commission an audit or inspection from an accredited firm.
Where we stop. TradeVerify is not a factory audit. We do not visit sites, test products or certify quality, safety or labour conditions, and we do not detect fraud with certainty. We evidence trade activity, one input alongside the other four categories. More on how we work and what the records cover.
Absence of a trade record is not proof of fraud. It is a question a real exporter can answer in one email, with a bill of lading attached.
