Supplier verification • Product evidence • Risk control

Industrial automation purchasing is unusually exposed to lifecycle, authenticity and compatibility risk. The same part number may be offered as current factory stock, surplus, open-box, repaired or used—often with very different evidence and warranty.

The right question is not simply “Is this supplier cheap?” It is: Can the supplier prove who they are, what the product is, how it was handled, what was tested and what happens if it fails?

Start with the decision-maker’s risk

Direct users

Will it keep running?

Prioritize exact fit, revision, condition, warranty, fast response and a realistic replacement path.

Procurement

Is the transaction controlled?

Verify the legal entity, bank account, quotation clarity, delivery terms, traceability and remedy.

Engineers

Is it technically correct?

Check full catalog number, hardware/firmware revision, options, safety status and test depth.

Three sourcing routes—not the same promise

Authorized channel

Best for current products, OEM-backed warranty and formal support. Ask for authorization scope and geography.

Independent specialist

Useful for obsolete and urgent parts. Evidence, test capability, condition grading and warranty become critical.

Marketplace trader

May locate stock quickly, but the actual seller, inventory control, traceability and remedy must be verified.

Build an evidence ladder

Do not let one attractive photo carry the entire decision. Strong qualification combines four kinds of evidence.

A. Business evidence Registration, address, domain email, bank-account match, real staff and reachable support.	B. Product evidence Full part number, serial/nameplate, revision, condition, date code, packaging and accessories.
C. Process evidence Receiving inspection, controlled storage, ESD protection, traceability and test records.	D. Transaction evidence Detailed quotation, delivery terms, warranty, return process and written non-conformance remedy.

The 15-point supplier checklist

1–3. Supplier identity

1. Confirm legal name, registration and physical address.

2. Verify manufacturer authorization—if claimed.

3. Match the beneficiary bank account to the contracting entity.

4–6. Product identity

4. Confirm the complete part number, suffixes and options.

5. Check lifecycle: active, mature, discontinued or obsolete.

6. Define condition in writing—never accept “new original” alone.

7–9. Evidence & authenticity

7. Ask for provenance and traceability appropriate to risk.

8. Require current photos of the actual unit or batch.

9. Review labels, serials, packaging and tamper indicators together.

10–12. Engineering capability

10. Define the functional test scope and request measured results.

11. Test response quality with a precise technical question.

12. Ask whether stock is owned, consigned or brokered.

13–15. Protection after purchase

13. Warranty
Duration, start date, exclusions and remedy.

14. Packaging
ESD, moisture, shock and export protection.

15. Payment
Use terms proportional to supplier and order risk.

A fast qualification shortcut

Ask the supplier to send one current photo showing the actual part, its full nameplate, today’s date and your company name—then ask what was tested and what the warranty covers. A competent supplier should answer consistently, not defensively.

100-point supplier scorecard

Category	Weight	What good looks like
Business legitimacy	15	Entity, address, staff and bank data align
Product identification	20	Part number, revision, condition and lifecycle are explicit
Traceability & evidence	20	Actual-unit evidence and records are available
Testing & technical ability	20	Test scope, equipment, results and competence are clear
Commercial protection	15	Quotation, warranty, delivery and returns are documented
Communication & response	10	Specific, consistent answers arrive on time

Suggested gate: 80+ = approved for normal orders; 65–79 = conditional approval or pilot order; below 65 = do not use without documented risk acceptance. Safety-critical applications require stricter engineering controls regardless of score.

Red flags that deserve a pause

Price far below market Especially when evidence is weak.	Stock photos only No current unit or batch proof.	Identity mismatch Company, email and bank data differ.
Vague condition “Original” replaces a precise grade.	PASS label as report No method, readings or criteria.	Pressure to prepay Before identity and evidence checks.

What to include in your RFQ

✓ Complete part number and required quantity

✓ Acceptable condition and revision

✓ Required-by date and destination

✓ Actual-unit photos and traceability

✓ Test scope and warranty

✓ Incoterm, payment and return terms

Frequently asked questions

Can a photo prove authenticity?

No. Combine photos with identity checks, full part-number review, labels, traceability, functional testing and incoming inspection.

What does “new original” mean?

It is too vague alone. Require a written condition: current factory stock, sealed surplus, open-box, repaired/refurbished or used.

What belongs in a test report?

Unit or batch ID, date, equipment, test scope, readings, pass criteria and the responsible technician.

How should obsolete parts be handled?

Confirm lifecycle and migration options, then tighten controls for age, storage, provenance, revision, testing and warranty.

Which certificate proves authenticity?

No generic certificate does. Verify the issuer, scope and direct reference to the item or batch.

How should a new supplier be tested?

Verify identity and banking, begin with a low-risk pilot, inspect incoming goods and review response quality.

What if the unit does not match?

Quarantine it, retain packaging, record unboxing and labels, avoid installation and notify the supplier in writing.

Can a low price still be legitimate?

Yes, but verify why: surplus, age, condition, missing warranty, brokered stock or a lifecycle change.
