Who is responsible for the supply?
Legal identity, manufacturing role, export responsibility, named contacts and the route for technical or warranty escalation.
For overseas distributors
Build a second source your team can sell.
Qualify evidence, trial controls and repeat supply before adding a Chinese industrial membrane line.
A backup line must work beyond the sample.
Distributor risk appears after the first quotation: unclear model coverage, inconsistent documents, packaging gaps, channel conflict and terms that cannot support repeat orders.
MembraLink puts the commercial and evidence questions into one review so your sales, technical and purchasing teams can see the same open items before a trial.
- Current portfolio and application gaps
- Destination markets and expected annual demand
- Required certificates, labels and shipping documents
- Sample method, evaluation owner and acceptance criteria
Four questions before a distributor trial.
Each workstream ends with recorded evidence, an unresolved item or a buyer decision. Unknowns are not filled with assumptions.
Which demand can the line cover?
Application, format and model scope are reviewed against manufacturer-origin documents and your stated market demand.
Can the trial connect to later orders?
Sample identity, serial or batch information, supplied test records and the intended repeat-order document trail are linked.
Do the terms support distribution?
MOQ, price validity, packaging, lead time, Incoterm, payment milestones and repeat-order conditions are recorded together.
From portfolio gap to controlled trial.
The sequence is designed to stop weak options early and preserve buyer control over the final commercial decision.
Confirm target applications, missing models, destination, annual demand and the reason for a second source.
Collect supplier, product, quality, export and commercial information with a named source for each item.
Agree sample identity, buyer tests, document package, responsible people and a clear acceptance outcome.
Record what must remain consistent for order placement, shipment, batch review, claims and warranty handling.
What your team receives.
The output is a decision file for internal review, not an unfiltered supplier list or a claim of product equivalence.
Qualification summary
The proposed source, intended use, evidence reviewed, open items, owner and recommended next decision.
Product and document matrix
Model scope, stated test conditions, document issuer, certificate scope and items still requiring confirmation.
Trial and batch trail
Sample identifiers, supplied records, buyer test outcome and the connection expected for a later production order.
Commercial risk register
Terms, deviations, unresolved dependencies and decisions that remain with the distributor before commitment.
Important: MembraLink does not certify a manufacturer or guarantee destination approval. Final qualification, contract approval and volume allocation remain with the buyer.
Buyer working guides
Use the evidence route before you shortlist.
These guides help a distributor define the source, product and operating evidence that should exist before a trial or portfolio decision.
Supplier qualification
How to qualify a Chinese RO membrane manufacturer
A 20-point route from legal identity and production evidence to inspection, payment and repeat-order controls.
Replacement selectionHow an RO replacement element is actually shortlisted
Separate the installed model code from the plant data and acceptance criteria that decide whether a candidate should proceed.
Start with the portfolio gap, not a generic price list.
Tell us the destination, application, expected volume, required documents and trial objective. We will structure the next evidence questions.
