What documents should a buyer request from a Chinese equipment manufacturer?
Which legal identity documents should the buyer request first?
The starting document is the business licence (营业执照). It establishes that the entity exists, is in normal operating status, and is authorised to do specific business activities. It carries the Unified Social Credit Code (USCC), an 18-character identifier that is the supplier’s permanent identity in Chinese public records.
From the business licence the buyer can verify: registered name, USCC (cross-checkable in the SAMR National Enterprise Credit Information Publicity System), registered address, registered capital, incorporation date, and — critically — the registered business scope. The scope indicates whether the company’s declared activities clearly include manufacturing activity for the equipment category; where the scope does not align with the quoted equipment, the buyer should verify the production entity, factory address, and contractual accountability before treating the supplier as the manufacturer. A general tax registration document is sometimes requested in addition, but the licence covers the same identity information at this stage.
Which quality-management certificates matter during qualification?
ISO 9001 is the baseline quality-management certification expected of any export-oriented Chinese manufacturer. The certificate is issued by an accredited certification body — it carries the certification body’s name and a certificate number that resolves in the issuing body’s public registry. Where possible, cross-check through IAF CertSearch or the relevant accreditation body — that verifies both the certificate itself and the accreditation status of the certification body.
Project-specific extensions may also apply: ISO 14001 (environmental management) is often required for lender-financed projects; ISO 45001 (occupational health and safety) is common in heavy industry; ISO 13485 is the equivalent for medical devices. Verify each in the issuing body’s registry rather than relying on the printed PDF.
Which product certificates and type-test reports should be checked?
The certifications required depend on the equipment and the destination market:
- CE marking for equipment going to the EU — the Declaration of Conformity should identify the manufacturer, applicable EU legislation, relevant standards, and product covered. Where the conformity assessment route requires a notified body, the notified body number and scope should be checked against the EU’s NANDO database.
- IECEx or ATEX for equipment destined for hazardous areas — the certification carries the certification body name and a unique certificate number.
- IEC type-test reports for electrical equipment (transformers, switchgear, generators) — these name the testing laboratory; the lab’s accreditation can be verified with the relevant accreditation body.
- Sector-specific certifications — Solar Keymark for solar thermal, pressure-vessel certifications (ASME, PED), and others as the project requires.
What audit and capacity evidence should accompany the documents?
A recent third-party factory audit report — from SGS, Bureau Veritas, TÜV, or an equivalent — establishes production capability beyond the certifications. The audit covers staffing, equipment, QC processes, calibration management, and production capacity.
Supplementary evidence: production-line photographs (with recognisable details, not stock images), capacity figures substantiated by recent shipping records or customs data, and descriptions of QC equipment with calibration certificates for critical instruments.
What inspection reports should the supplier share, and how recent should they be?
More telling than capacity claims are third-party inspection reports from recently completed contracts — pre-shipment inspections, FAT witnessing, or in-process inspections by an independent inspection company. These show how the supplier performs under actual scrutiny. Patterns of defects, corrective actions, and time-to-resolution are visible in the reports.
Suppliers are sometimes reluctant to share inspection reports from other clients’ contracts on confidentiality grounds. Redacted versions (client name and commercial detail removed, inspection content preserved) are usually a reasonable compromise.
What counts as a real customer reference?
A logo strip on a presentation slide is not a reference. A real reference is a contactable end client who has received the supplier’s equipment for an installation comparable in scale and complexity to the planned project. The buyer asks the supplier for the project name, the country of installation, the year, the equipment scope, and a contact at the end client.
A short reference call — 15 minutes — covering whether the equipment performed to specification, whether documentation was clean, whether commissioning had complications, and whether after-sales support has been responsive, surfaces information no document does.
| Document | What it helps verify | What it does not prove | How to check |
|---|---|---|---|
| Business licence (营业执照) | Legal existence, business scope, registered capital, address | Production capability, financial health, delivery reliability | Look up USCC in SAMR National Enterprise Credit Information Publicity System |
| ISO 9001 / 14001 / 45001 | Documented management system in place | Day-to-day quality of execution | Check certificate number in issuing body’s registry; cross-check via IAF CertSearch |
| CE / IECEx / ATEX | Product compliance with the named directives | That the shipped unit matches the certified design | Read the DoC; verify notified body in NANDO if applicable; match to the equipment being quoted |
| IEC type-test reports | Design tested against the standard | Routine-test quality of the specific unit | Verify the testing laboratory’s accreditation |
| Third-party factory audit | Production capacity, QC processes, calibration | Performance on the specific contract | Read the audit body’s name and date; request a sanitised copy when older |
| Inspection reports (recent contracts) | How the supplier performs under scrutiny | What it will look like on your contract | Look for defect classification, corrective actions, time-to-resolution |
| Reference contracts | Comparable delivery and post-installation behaviour | Performance on equipment differing in scale or specification | Contact the named end client directly; 15-minute call |
How Sinospect compiles the documentation dossier
Sinospect requests, organises, authenticates, and reviews the full documentation dossier on the buyer’s behalf. Certificates are verified in the relevant registries; reference contacts are spoken with directly; inspection reports are read for what they actually say rather than what they appear to say. The output is a structured qualification dossier that travels with the buyer through the rest of the procurement cycle.
See the cluster guide on supplier qualification for how this step sits in the broader workflow, or how Sinospect works for the full execution method.
Frequently asked questions
What if the supplier’s certifications are in Chinese only?
That is normal. Most Chinese-issued ISO certificates have an English translation alongside the original; international product certifications (CE, IECEx) are issued in English. Request both versions. A supplier that cannot produce an English-readable version of any certification is one that has not engaged with international markets.
How recent should the documents be?
Business licence: current as of the request. ISO certificates: within the validity period printed on the certificate (typically a 3-year cycle). Factory audit reports: ideally within 18 months. Inspection reports: from contracts in the last 24 months. Older documents are not automatically invalid but warrant questions about why nothing more recent exists.
Can the buyer share the documentation with the project lender or end client?
Usually yes, but ask the supplier first. Most documents (business licence, ISO certs, product certifications) are non-confidential. Audit reports and inspection reports may contain commercial detail the supplier prefers not to circulate. NDA arrangements solve this when stricter handling is needed.
What happens when the supplier provides only some of the requested documents?
The qualification dossier is treated as incomplete and the supplier moves into a conditional state. Sometimes a missing document reflects timing (a renewal in progress) and can be cleared in days; sometimes the gap is permanent. The decision to proceed should be made with the gap explicitly noted, not silently absorbed.
