Why This Matters
Verifying a factory is simpler than verifying a trading company — if the production line is real, it's real. But factories have their own traps. This is how I personally verify chemical factories: making sure they can actually produce and actually export. The lessons here are hard-earned.
1. First, Verify the Company Is Real
Business License
Check: company name, U.S.C.C. number, date of establishment, and business scope (must include "chemical production" or equivalent).
National Credit Information Publicity System (gsxt.gov.cn)
Check: operating status ("存续" = active), administrative penalties, abnormal operations, and serious violations. If the site returns an error from your IP, ask your freight forwarder or local partner to check it for you.
Tianyancha / Qichacha / Qixinbao
Key checks:
- Paid-in capital: Chemical production needs real financial backing — too low warrants caution
- Social security contributors: 0–1 employees is a major red flag
- Risk records: environmental violations, production safety incidents, product liability disputes
- Shareholder and affiliated company info: some small factories are affiliates of larger companies, which can actually be a stability indicator
2. Chemical Production Permits — Don't Skip This
Hazardous Chemical Safety Production License
Required if your product falls under hazardous chemicals. How to verify: provincial Emergency Management Department websites, or the national portal at www.mem.gov.cn → Hazardous Chemical Registration System. Check: license number, company name, validity period, and permitted scope.
Exporting hazardous chemicals without this license is illegal — cargo can be seized by customs, and the buyer can be implicated.
National Industrial Product Production License
Some non-hazardous chemical products still require this. Verify via your province's government services portal using the company's U.S.C.C. number.
Environmental Impact Assessment + Completion Approval
Required for all chemical factories. Operating without EIA approval is illegal — the factory risks mandatory closure. Request the documents or cross-verify via the local environmental bureau's public records.
Pollution Discharge Permit
Publicly searchable at permit.mee.gov.cn. No permit or expired permit = illegal operation. Verify: permit status, permitted scope, and validity period.
Fire Safety Approval
Required for chemical factories — request it directly. A factory that can't show its fire safety approval is a factory you should not be working with.
Historical Incident Records
Search Tianyancha/Qichacha for keywords: "生产安全事故" (production safety accident), "爆炸" (explosion), "泄漏" (leak), "环保处罚" (environmental penalty). Any positive hit needs a direct explanation from the supplier.
3. Product Compliance Documents
MSDS (Material Safety Data Sheet)
Both Chinese and English versions required. Verify manufacturer name, CAS numbers, and emergency procedures. If the supplier can't clearly explain inconsistencies, move on.
COA (Certificate of Analysis)
Request a recent batch COA. Contact the testing lab listed to verify the report number.
Hazardous Goods Documentation (if applicable)
- Dangerous goods packaging certificate: issued by Chinese customs
- Transport hazard identification report: from Shanghai Chemical Research Institute, Qingdao Customs Technical Center, or equivalent
- Chemical classification report: confirms UN number and packaging category
Factories selling hazardous goods without packaging certificates should be excluded immediately.
4. Production Capacity Verification — Video Is the Best Tool
Live Video Inspection
Request a WeChat/Zoom/Teams video call. The supplier should:
- Film the factory gate sign (full company name + street address)
- Walk around the production line, QC area, and warehouse — not a fixed camera angle
- Pick up a product or semi-finished item at random and show its markings
- Use Baidu Maps or Gaode Maps to show real-time location — verify it matches the registered address
- For hazardous goods factories: show proper hazard labels and separated storage areas
A factory that only shows you fixed camera footage with no real walking around — be suspicious.
Baidu/Gaode Street View Verification
Search the factory's registered address on Baidu Maps or Gaode Maps street view — verify it matches the description. Red flag: residential addresses, no visible factory building.
5. Export Track Record
Customs Export Records
Request the past 12 months of export declarations (prices can be redacted). Check: export destination countries match what the supplier claims, and whether they have a history of exporting the specific chemical category. Verify through Panjiva, ImportGenius, or similar data providers.
Bank Reference Letter
Request from the bank's opening branch. Verify independently via the bank's official public phone number.
Credit Insurance
Ask if the supplier is insured with Sinosure (China Export & Credit Insurance Corporation). Suppliers approved by Sinosure carry higher credit credibility.
6. Payment Terms
Best: Irrevocable L/C at sight via a major Chinese bank
Acceptable: DP (documents against payment)
Prepayment terms depend on relationship length and transaction size — no fixed percentage applies universally.
Contract Protection Clauses I Recommend
- Composition/purity guarantee: each batch COA must match agreed specifications
- Pre-shipment inspection (PSI): commission SGS, BV, or Intertek to sample at the factory — payment released only after passing
- Post-arrival re-inspection right: retain the right to have a third-party test at destination port
- Arbitration clause: HKIAC or SIAC, governed by CISG
7. Red Flags
- No safety production license for hazardous chemicals — illegal, exclude immediately
- Cannot provide EIA approval or pollution permit — operating illegally, risk of shutdown
- Fire safety approval missing — non-compliant
- Factory shows abnormal/closed status on Tianyancha — extreme risk
- Video shows fixed/staged footage, no real movement — possible virtual factory
- Price significantly below market (>20%) — high quality risk
- Refuses sample testing or demands full payment before shipping — very high risk
- Claims to have a factory but can't show any production equipment — may have no real capacity
A practical note: I've seen factories without ISO certification that had clean export histories, good reputation, and high responsiveness — and worked with them for 5–6 years without a single problem. I've also seen factories with every certification that were actually OEM operations with insufficient real capacity. Due diligence helps you avoid obvious traps — it doesn't guarantee you'll never hit one. The real reliability comes from ongoing communication, staying alert, and catching problems early.
Key Takeaways — Factories
Fixed camera footage isn't enough. Ask for a walk-around — production line, QC area, warehouse — in real time.
No license = no legal export. Check via www.mem.gov.cn or the provincial Emergency Management Department.
PSI via SGS/BV, composition guarantee in every contract, and post-arrival inspection rights — these are non-negotiable for first orders.
