Evidence-led supplier qualification and RFQ coordination for overseas membrane distributors and water-treatment EPCs.
MembraLink is an expert-led qualification and commercial-coordination service. We do not certify products, guarantee destination approval or claim affiliation with a manufacturer unless that relationship is confirmed in writing.
Qualification designed around channel fit, repeat orders and supply continuity.
A structured route from operating data and documents to a controlled trial order.
Know what is verified, pending and unavailable before commitment.
Your primary supplier does not need to fail before you qualify a second source. The right time to review evidence, samples, terms and response discipline is before a shortage, tender deadline or replacement cycle.
We structure the commercial and evidence review around repeat sales, channel fit and supply continuity.
We organise the RFQ around your feedwater, operating envelope, target permeate and acceptance requirements.
Service fit: recurring distributor demand, planned second-source qualification, industrial replacement programmes and EPC projects with a defined specification. One-off retail and household-membrane enquiries are outside the core service.
Price becomes meaningful only after the supplier, product evidence, response process and delivery route survive review.
A company profile or marketplace page does not prove manufacturing identity, production discipline, capacity or export responsibility.
A sample can perform well and still tell you little about repeat supply unless its model, batch, serial, test record and production date connect.
Commercial, technical and document questions handled by separate people create contradictions, missed deadlines and unpriced risk.
The website starts the conversation. The service is delivered through evidence, coordination and principal-level judgement.
Legal identity, manufacturing role, production capability, quality controls and export-document responsibility.
Model datasheet, stated test conditions, sample path, serial and batch traceability, certificate scope and validity.
One structured brief covering duty, quantity, documents, destination, commercial terms, deadline and open questions.
Contracting party, payment milestones, inspection, shipping documents, warranty route and buyer acceptance.
Jeff reviews what the factory can realistically promise, where the transaction can fail and what still needs proof.
The output is organised so commercial, technical and management teams can see the same evidence and the same unresolved risks.
| Workstream | What the file records | Why it matters |
|---|---|---|
| Supplier profile | Identity, manufacturing role, facilities, product scope, QC process and named contacts. | Separates manufacturer evidence from reseller claims. |
| Product matrix | Model, application, format, manufacturer-stated test conditions, documentation status and open items. | Prevents a nominal cross-reference from becoming an unsupported equivalence claim. |
| Sample & batch trail | Sample identifier, batch/serial information, supplied test records, buyer test result and disposition. | Connects qualification work to the product later ordered. |
| Commercial matrix | MOQ, price validity, lead time, packaging, Incoterm, payment milestones and repeat-order conditions. | Tests whether the second source can work beyond a one-time sample. |
| Risk register | Verified, pending and unavailable items; deviations; responsible party; decision deadline. | Makes uncertainty visible before commitment. |
Exact models, performance, certificates and availability are confirmed against manufacturer-origin documents for each RFQ.
Standard and low-energy elements for industrial process water, municipal duty and planned replacement programmes.
Options reviewed against pretreatment, foulant load, cleaning history, spacer design and recovery target.
Project-specific review of salinity, temperature, boron requirement, system configuration and manufacturer evidence.
Screened where hardness, organics, colour, suspended solids or upstream RO protection defines the duty.
A model cross-reference is not treated as proof of fit or performance. Dimensional fit and operating suitability are reviewed against the buyer’s data and the proposed manufacturer’s stated test conditions.
Buyer type, installed model or project duty, quantity, destination, documents and deadline.
Collect supplier, product, quality, commercial and export information; mark every open item.
Align technical questions, commercial terms, certificate scope, deviations and response ownership.
Connect sample identity and batch documents to buyer testing, inspection or pilot acceptance.
Confirm contract, payment, batch, shipping documents, warranty route and repeat-order conditions.
Jeff has spent more than three decades on the factory and international-trade side of cross-border business. He has owned and operated export factories, worked under demanding buyer quality systems and negotiated with Chinese manufacturers as an owner, not as a web-platform operator.
For MembraLink, he applies that experience to supplier capability, quality discipline, transaction structure and cross-border risk. The role of the website is to establish context and collect a structured RFQ. The critical judgement stays with a responsible person.
Each guide explains which evidence a buyer supplies, which evidence a manufacturer must provide and which decision remains with the buyer.
Why the installed model narrows the search but does not prove dimensional fit or operating suitability.
