Service · Development
Spec-to-sample coordination with a technical tech pack. Sample rounds, tolerances, and packaging — negotiated in writing so the factory can actually build to it.
Scope
What’s included
- Product brief and technical tech pack (materials, dimensions, tolerances, finish)
- Packaging and labelling specification
- Sample round management with pass/fail criteria per round
- Bill-of-materials and cost breakdown review
- Pre-production sample sign-off and factory readiness check
Process
From idea to production-ready
01
Discovery
Understand the product, buyer, price point, and non-negotiables. Turn that into a written brief.
02
Tech pack
Materials, dimensions, tolerances, colours, packaging, labelling — the level of detail the factory floor actually needs.
03
Sampling
Two or three sample rounds with named pass/fail criteria. Physical samples reviewed against the tech pack, not against memory.
04
Sign-off
Golden sample locked, packaging approved, BOM and cost confirmed — ready for a production PO.
Why work with Hansen
A quieter kind of sourcing — the one you actually wanted.
Shenzhen-based, PRD-wide
On-the-ground presence across the Pearl River Delta manufacturing hub — factories are hours away, not oceans.
No hidden commissions
I work for the buyer, not the factory. Audits and quotes are transparent; incentives are aligned with your outcome.
Spec-to-sample, in writing
Product briefs, tech packs, and pre-production samples with clear acceptance criteria — not verbal promises.
Pre-shipment QC
Independent inspections against AQL and your own spec, with pass/fail evidence — before the container leaves.
Questions buyers ask
Frequently asked.
Do you handle industrial design or CAD?
I coordinate with independent ID and CAD partners when needed. For most SKUs, a strong tech pack and factory-side engineering is sufficient.
Can you help protect the design?
Yes — NDAs with factories, staged information release, and (where the budget supports it) design patents or utility model filings in China.
What if the sample keeps failing?
Then it’s usually a brief problem, not a factory problem. We stop, tighten the tech pack, and often switch factories for the next sample round.
Ready when you are
Need help sourcing from China?
A short brief and I’ll respond within one business day, Shenzhen time. No obligation, no upsell — just an honest read on whether I’m the right partner for your project.
Decision support
What you receive
The work turns a product idea into written production instructions that a factory can discuss, quote, sample, and revise against.
- A technical brief covering materials, dimensions, tolerances, finish, packaging, and open decisions.
- Sample-round tracking with pass/fail criteria and a written list of changes for the next round.
- A production handover pack that records the approved specification, cost assumptions, and remaining risks.
Best fit
This service is useful when the product is not yet defined well enough for comparable factory quotes, or when repeated sample changes are creating cost and schedule drift.
Scope boundary
Development coordination does not replace product safety, regulatory, or laboratory testing. Those requirements should be identified early and handled by the appropriate qualified testing provider.
