Battery supplier verification
A supplier’s brochure tells you what it wants to be. Verification tells you what it is. Before you pay a deposit, three things must check out independently: the legal entity, the certificates, and the claimed capacity.
Layer 1 — Verify the legal entity
Every legitimate Chinese company has a business licence carrying a unified social credit code (统一社会信用代码) — an 18-character alphanumeric identifier. That code is the key to the National Enterprise Credit Information Publicity System (gsxt.gov.cn), a free public register maintained by the State Administration for Market Regulation.
Look up the code and confirm four fields against what the supplier told you:
- Business scope — does it say production and manufacturing (生产/制造), or only trading (贸易)? A trading company cannot legally run a battery production line, yet many present themselves as factories.
- Registered capital — Chengguang Power Tech Co., Ltd.’s registered capital is RMB 50 million. A “factory” with registered capital of RMB 100,000 is a red flag that it cannot fund a production line.
- Legal representative and registered address — these should match the licence you were sent and the address you will ship to.
- Operating status — the register shows whether the entity is in normal operation, revoked, or subject to enforcement.
A supplier that will not share its unified social credit code before an order will not share anything useful after it. There is no legitimate reason to hide the licence.
Layer 2 — Verify the certificates
Certificates are point-in-time documents, and they can be expired, suspended or simply faked. Do not accept a certificate image; ask for the number and check it.
| Certificate | What it covers | How to check it |
|---|---|---|
| IATF 16949 | Automotive quality management system | Confirm the number and scope with the issuing certification body (see IATF Global Oversight). |
| ISO 9001 | General quality management | Verify on the certifier’s register; confirm the scope actually includes batteries. |
| ISO 45001 / OHSAS 18001 | Occupational health and safety | Check the certificate number and validity window. |
| Market certs (CE, SASO, etc.) | Destination-market conformity | Confirm the standard and the notified body or issuing authority. |
An IATF 16949 certificate is issued for a 3-year cycle with annual surveillance audits. A certificate can therefore be within its printed expiry date and still be suspended for a failed audit — the paper date is not proof of status. The number is what lets you confirm current standing. Chengguang Power Tech Co., Ltd. holds IATF 16949, ISO 9001, ISO 45001, OHSAS 18001 and can supply the certificate numbers on request, the same as any candidate you should be willing to verify.
Layer 3 — Verify the claimed capacity
Capacity claims are the easiest number to inflate and the hardest for a buyer to test from a desk. The trick is that a real production line has bottlenecks, and the bottlenecks have to agree with each other. Three numbers must be consistent:
- Casting capacity — how many grids per day the casting machines produce, which caps plate output.
- Formation capacity — how many cells the formation (charging) circuits can process at once, multiplied by cycles per day. Formation is usually the real bottleneck.
- Headcount — the number of line workers, which has to support the claimed throughput.
If a factory claims 40,000 batteries a day but its formation area holds a fraction of that, the claim is marketing. Ask for the three numbers separately and check they multiply out. The factory audit guide shows you what to look at on site to confirm this.
The verification checklist
| Item | What to request | Pass signal |
|---|---|---|
| Business licence | Unified social credit code | Matches gsxt.gov.cn; scope is production. |
| Registered capital | From the register | Consistent with running a production line. |
| IATF 16949 / ISO 9001 | Certificate number + scope | Verifiable with the certifier. |
| Capacity | Casting + formation + headcount | The three numbers agree. |
| Ownership | Factory address vs registered address | They match; a video walkthrough is offered. |
| Export record | Bill of lading sample or customer reference | They can name destination markets they serve. |
What fakes look like
- Borrowed photos — a trading company photographs another factory’s line. A live video call with a specific instruction (hold up today’s date) separates the owner from the tourist.
- Expired or suspended certificates — the paper looks current, the number does not check out.
- Inflated capacity — the brochure claims a number the formation area cannot support.
- A mailbox address — the registered address is an office, not the plant you are told exists.
None of these requires an on-site visit to catch. Two of the three layers — the licence and the certificates — verify from a desk; only capacity truly benefits from eyes on the line.
Where verification fits in the sequence
Verification sits between the shortlist and the audit. It is cheap and fast — an hour of register checks — and it removes the candidates that would waste a full audit. Run it, then audit the survivors, then issue the RFQ.
Dingwei Battery provides OEM and private-label battery programs manufactured by Chengguang Power Tech Co., Ltd. (founded 2002). The full sourcing sequence is in the sourcing guide; see China battery industry regions to build a shortlist worth verifying, and the how to choose a manufacturer guide to score the survivors.
The full register checklist
gsxt.gov.cn is the first stop, but a thorough check uses four public registers, all free:
- National Enterprise Credit Information Publicity System (gsxt.gov.cn) — the licence, unified social credit code, business scope and operating status.
- China Judgments Online / enforcement records — whether the entity is a defendant in unpaid-debt or quality disputes.
- The certifier’s certificate register — confirms an IATF 16949 or ISO 9001 number is current and the scope matches.
- Customs / export records — where available, confirms the entity actually exports, not just advertises.
None of these requires an on-site visit. Between them they answer the two questions that matter before you pay anything: is this entity real, and is it what it says it is?
A worked verification example
Run a supplier through the checks and the result is a pass/fail list, not a feeling:
| Check | Supplier claims | Register shows | Verdict |
|---|---|---|---|
| Unified social credit code | 18-character code provided | Resolves to a different name | Fail — stop |
| Business scope | “Factory, 20 years” | Scope is trading (贸易) only | Fail — stop |
| Registered capital | “Large manufacturer” | RMB 100,000 | Fail — stop |
| IATF 16949 | “Fully certified” | Certificate suspended | Fail — stop |
| Capacity | 40,000/day | Formation area supports a fraction | Investigate |
In this example four of the five checks fail outright, and the correct action is to walk away before spending a single day on an audit. That is the value of verification: it removes candidates for free that an audit would have removed for US$1,500–3,000.
The sample as a verification tool
A production sample is evidence, but only if you ask the right question about it. When the sample arrives, confirm three things:
- It came from a production run, not a lab bench — ask for the batch record that ties it to the line.
- It carries its own test report — CCA and capacity, on the named test basis, not a generic datasheet.
- It matches the licence — the label should name the entity you verified, not a different trading company.
A supplier that can produce a sample with a batch record and a test report is showing you its process control, not just its product.
Video walkthrough protocol
If you cannot visit, a live video call replaces some of the visit. Make it verifiable rather than a tour video:
- Ask to start at the factory gate with the company sign visible.
- Ask them to hold up a dated document or today’s newspaper on camera.
- Ask to walk the line in production order, and pause at the curing room and the formation area.
- Ask a technical question at each stop — a real factory answers, a trader stalls.
A video call is not as good as an audit, but it is dramatically better than a photo set, and it costs nothing. Use it as the bridge between desk verification and the on-site audit.
The Author's Take
Position: In my view, verification is the cheapest stage in sourcing and the most expensive one to skip — two of its three layers can be checked from a desk, for free, before you pay a cent.
Reasoning:
- The unified social credit code on gsxt.gov.cn reveals whether the entity is a factory (生产/制造) or a trader (贸易), for free.
- A certificate is point-in-time; the number checked against the certifier's register is what proves current standing, not the printed date.
- Capacity claims must multiply out — casting, formation and headcount have to agree, or the number is marketing.
Disclosure: this is the author's editorial judgment and field experience, not a verified technical claim.

Verification is the cheapest stage in the whole sourcing sequence and the most expensive one to skip. Run it on every candidate, every time.
Frequently asked questions
What is the single most reliable way to confirm a supplier is a real factory?
Check the unified social credit code (统一社会信用代码) on the business licence against the National Enterprise Credit Information Publicity System (gsxt.gov.cn) — the licence carries an 18-character code, and the register shows the business scope, registered capital and legal representative.
How long is an IATF 16949 certificate valid?
An IATF 16949 certificate is issued for a 3-year cycle with surveillance audits, so a certificate that looks current can still be suspended — always check the number against the certifier’s register, not just the expiry date on the paper.
Can a supplier fake its production capacity?
Yes, on paper. Daily output is only believable when 3 numbers agree — the casting capacity, the number of formation circuits and the actual staff count — so cross-check the claim against the equipment you see, not the brochure.
Why does verification matter more than price?
A trading company posing as a factory typically adds 5–15% and removes your quality control — so an unverified “cheaper” quote is usually the most expensive option in the end.
