DUE DILIGENCE
Why Supplier Qualification Matters
Finding the right supplier in China is one of the most important commercial decisions an importer will make. The difference between a capable manufacturer and the wrong manufacturer rarely becomes obvious during the quotation stage. It becomes apparent months later — through quality failures, project delays, compliance rejections, unexpected costs, warranty disputes or damaged customer relationships.
Our objective: reduce procurement risk, improve supplier performance, and build long-term supply chains that continue delivering value over years, not one shipment.
Every supplier we recommend has passed the framework below. Many do not.
The Dracon Supplier Qualification Framework
Phase 1 — Project Discovery & Technical Review
Before approaching any manufacturer, we define exactly what is being sourced.
-
Review of architectural and engineering drawings, specifications and BOQ
-
Material schedules and performance requirements
-
Compliance obligations against applicable standards
-
Delivery programme and commercial objectives
Output: A structured Chinese-language tender package so every shortlisted manufacturer prices the same scope — enabling genuine like-for-like comparison.
Phase 2 — Manufacturer Identification
We do not source from advertising platforms. Manufacturers are identified through long-standing industry relationships, direct market research and sector-specific networks.
Selection criteria: manufacturing specialisation, years operating, export markets served, production capability, project experience, factory scale, product suitability, industry reputation.
Depending on the project, we may review anywhere from five to more than thirty manufacturers before progressing to detailed assessment.
Phase 3 — Business Verification
A business registration alone does not prove manufacturing capability. We verify:
-
Chinese business registration and legal operating status
-
Shareholding structure and ownership history
-
Manufacturing licences and export registration
-
Years trading and financial maturity
-
Previous litigation or ownership changes where relevant
-
Operational consistency over time
Phase 4 — Factory Capability Assessment
This stage determines whether a supplier can actually manufacture what they claim.
Assessed: factory size, production lines, manufacturing equipment, automation and CNC capability, welding systems, surface finishing, assembly processes, workforce capability, engineering support, production planning, monthly capacity, scalability.
We also assess whether critical production processes are performed in-house or subcontracted. This distinction is often decisive for quality control and delivery certainty.
Phase 5 — Quality Management Systems
Quality should never rely solely on final inspection. We review how quality is managed throughout production:
-
Incoming material inspections
-
First article and in-process inspections
-
Final inspection procedures and hold points
-
Calibration and traceability systems
-
Non-conformance reporting and corrective action
-
Internal testing capability
-
Continuous improvement systems
Where appropriate, we recommend third-party inspection through SGS, TÜV, Bureau Veritas or V-Trust at critical milestones before shipment approval.
Phase 6 — Compliance Verification
This is where we most regularly identify risk. Many manufacturers believe their products comply because they hold certificates. Certificates are often expired, issued for different products, issued under previous factory ownership, not recognised in New Zealand or Australia, laboratory reports rather than product certification, or based on overseas standards only.
We independently review:
-
Product certifications and test reports
-
Factory and quality system certifications
-
Declaration documents and technical data
-
Material traceability and steel grades
-
Welding procedures and structural testing
-
Fire, thermal and environmental testing
Where possible, documentation is cross-checked directly with issuing authorities — not accepted at face value.
Phase 7 — Supply Chain Assessment
Strong factories require strong suppliers. We assess:
-
Raw material sourcing and approved supplier systems
-
Steel, aluminium, glass, hardware, electrical and plumbing component supply
-
Supply continuity and inventory management
-
Alternative sourcing capability if primary supply fails
Phase 8 — Commercial & Project Management Assessment
Manufacturing capability means little without effective project management. We assess English communication, technical understanding, responsiveness, drawing interpretation, documentation quality, reporting capability, engineering support, problem solving and commercial professionalism.
Phase 9 — Comparative Supplier Evaluation
Once due diligence is complete, suppliers are compared across weighted criteria — not price alone:
-
Capability and compliance
-
Commercial competitiveness
-
Quality systems and engineering support
-
Production capacity and delivery performance
-
Communication and supply chain stability
-
Long-term partnership potential
This produces informed commercial decisions rather than selecting on price.
What Disqualifies a Supplier
Suppliers are removed from consideration where:
-
Certificates cannot be verified against issuing bodies
-
Test reports are expired, mismatched or cover a different product
-
Critical production processes are subcontracted without disclosure
-
Factory capability does not match claimed capacity
-
Quality systems rely solely on final inspection
-
Communication or engineering support is inadequate
-
Export experience in regulated markets cannot be evidenced
-
Ownership, litigation or operational history raises unresolved risk
From an initial pool of 55 container home factories, for example, only a small Tier 1 group consistently met compliance and capability. That ratio is typical.
Long-Term Supply Chains Create Higher Returns
One-off sourcing rarely delivers the greatest value. The greatest commercial advantage comes from a supply chain that improves over time. As relationships mature:
-
Supplier performance improves
-
Pricing becomes more competitive
-
Quality systems strengthen
-
Engineering knowledge accumulates
-
Lead times reduce
-
Commercial leverage increases
The result is not simply lower pricing. It is a procurement system that continues generating value year after year.
This is why Dracon deliberately focuses on a smaller number of long-term supplier relationships rather than transactional, per-project sourcing.
Due Diligence in Practice
-
New Zealand Windows & Doors — More than twenty Chinese window manufacturers reviewed. Many claimed AS/NZS 2047 compliance. Only a small number demonstrated genuine capability through independently verified testing, documented quality systems, engineering support and previous export history into regulated markets.
-
Aluminium Ringlock Scaffolding — Multiple manufacturers assessed across aluminium grades, welding procedures, extrusion quality, dimensional consistency and export capability. The selected manufacturer supplied major international scaffold brands using the same production systems and quality controls.
-
Modular Housing — Many factories advertise premium modular homes online. Detailed audits often reveal significant differences in engineering capability, structural design, insulation systems, waterproofing, electrical standards and export experience.
Frequently Asked Questions
What is supplier due diligence?
The process of independently verifying a manufacturer's legal status, capability, quality systems, compliance documentation and supply chain before appointing them to a project.
How is this different from getting factory quotes?
Quotes tell you price. Due diligence tells you whether the factory can actually deliver to specification, on time, with verifiable compliance. Price without capability is a liability.
How many suppliers do you typically review per project?
Anywhere from five to thirty-plus, depending on category and complexity. Most are eliminated before pricing is requested.
Do you receive commission from suppliers?
No. We work for the buyer. Suppliers are recommended on capability, compliance and commercial suitability.
Can certificates be trusted at face value?
No. Expired, mismatched, superseded or unrecognised certificates are common. We verify against issuing bodies wherever possible.
Do you use third-party inspection?
Yes — SGS, TÜV, Bureau Veritas and V-Trust at critical production milestones where appropriate.
What happens if a supplier fails due diligence?
They are removed from the shortlist. We report the finding and continue with the remaining pool.
Ready to Engage?
