How we work

A four-stage route from inquiry to repeat supply.

01 · Sourcing brief

Your requirement is turned into a supplier-ready brief: drawings or specification, quantity, target market, compliance scope, evidence requirements and timeline.

02 · Supplier qualification

Candidate facilities are shortlisted and qualified against the brief—capability, quality system, export experience and reference orders. Unverified claims are not presented as fact.

03 · Samples & inspection plan

Samples, test reports and an agreed inspection plan define acceptance before volume commitment. Factory visits and audits can be arranged at this stage.

04 · Repeat supply

Approved production moves to repeat orders with controlled documentation, change management and shipment evidence.

Transparent role: TUOLAN TRADE is an international trading and sourcing company. Manufacturing is performed by the selected and approved production facility for each program.

Factory visits and supplier audits by appointment.

For qualified B2B projects, the selected production or integration facility may be visited after the scope, supplier and required documents are confirmed. Share the audit purpose, document checklist and preferred dates in advance.
