Synthetic leather materials for global B2B projects
About WINIW
WINIW is a synthetic leather company based in Jinjiang, Fujian, China. We support manufacturers, product developers, importers and material sourcing teams that need synthetic leather options matched to an application, processing method and defined acceptance criteria.
Our public product range covers microfiber leather, microfiber suede, PU leather, PVC leather, silicone leather and synthetic chamois. The purpose of this page is to show who we are, how we work with B2B projects and which company or product evidence a buyer should verify during supplier qualification.
WINIW at a Glance
These company details are limited to information consistently published on the current website. Buyers who require legal, manufacturing or capacity verification should request the applicable current documents rather than rely on an unsupported site-wide number.

The video from the original About Us page is retained here as a company introduction. When using video or images for supplier evaluation, connect what is shown to the specific legal entity, operating location and production scope you need to audit.
- Use the video to understand the company and product context.
- Use current documents to verify legal and commercial facts.
- Use a factory audit or live review when site-level manufacturing evidence is required.
- Use SKU-specific TDS and reports for product performance claims.
Material Range and Application Coverage
WINIW organizes its website by material family and by end-use industry. That lets a buyer begin with a known construction or start from the application and its failure risks.
Microfiber Leather
For projects evaluating a microfiber-based structure, surface finish and application-specific durability profile.
Microfiber Suede
For suede-like surfaces where nap, hand feel, colorfastness, shedding and backing need to be specified.
PU Leather
For polyurethane-coated material projects that require a defined substrate, coating route, texture and performance brief.
PVC Leather
For vinyl leather applications that need repeatable finish, project cost control and destination-market verification.
Silicone Leather
For projects specifically evaluating a silicone-coated surface and its compatibility with the intended construction.
Synthetic Chamois
For automotive, household, glass and precision wiping projects using PVA or microfiber chamois routes.
What Buyers Should Verify During Supplier Qualification
A credible About Us page should help procurement teams ask better questions. Company, factory, quality-system and product-test documents prove different things and should not be treated as interchangeable.
| Qualification area | What to request | What it helps verify | Important boundary |
|---|---|---|---|
| Company identity | Current business registration, legal name, registered address and authorized contact details. | The entity responsible for quotation, contract, invoice and export documents. | A brand name or website footer is not a substitute for legal documentation. |
| Manufacturing model | Factory list, ownership or cooperation relationship, processes handled at each site and audit availability. | Where the proposed material is made and which operations are controlled by which party. | Do not infer that every product comes from one site or identical process. |
| Capacity and delivery | Applicable production line, realistic capacity for the material, current load, MOQ and lead-time confirmation. | Whether the proposed supply route fits the order volume and timing. | Capacity must identify the material, line, unit and period; a site-wide marketing number is not enough. |
| Quality system | Incoming, in-process and final inspection procedures; traceability method; calibration and non-conformance controls. | How specifications are controlled from raw material through shipment. | A quality-system certificate does not automatically prove every product performance claim. |
| Product evidence | TDS, sample approval record and test report identifying the exact SKU, method, conditions and report date. | Whether the candidate material meets project acceptance criteria. | A report for one sample should not be generalized to an entire material family. |
| Compliance | Buyer restricted-substance list, destination-market requirements and applicable declarations or third-party reports. | Which requirements were actually checked for the proposed order. | REACH, RoHS, OEKO-TEX and application standards have different scopes; verify applicability individually. |
How WINIW Supports a Custom Material Project
Custom development works best when appearance, processing and performance are defined together. The exact scope, sample timing, MOQ and production lead time should be confirmed for each material rather than presented as one universal policy.
Define the application
Share the finished product, component, environment and current material problem.
Set the specification
Provide material route, thickness, width, backing, color, grain, hand feel and quantity.
Set the evidence
Identify required tests, restricted substances, reports and buyer acceptance limits.
Sample and evaluate
Approve the candidate material in the intended cutting, sewing, lamination or forming process.
Confirm production
Lock the approved reference, commercial terms, inspection plan and delivery requirement.

Commercial and technical coordination
WINIW's project team helps collect application requirements, coordinate material matching, arrange samples and support commercial communication. For a technical decision, buyers should still approve the exact material against their own process and acceptance criteria.
- Application and material requirement review
- Color, grain, backing and surface discussions
- Sample, TDS and available report coordination
- Quotation, production and shipment communication
- Issue documentation and follow-up when a project needs review

Our Working Principles
The original company page emphasizes win-win cooperation. For B2B sourcing, we translate that value into three practical commitments that can be evaluated during a project.
Clear Requirement Boundaries
We separate a material-family description from an exact SKU claim and ask for the application, process and test conditions before recommending a route.
Evidence Before Approval
Samples, TDS, test reports and certificates should be reviewed for their scope. Marketing language should not replace project-specific evidence.
Long-Term Project Coordination
Color, surface, production reference and issue records need consistent communication from development through repeat orders.
FAQ: About WINIW and Supplier Qualification
Practical questions for buyers reviewing WINIW as a synthetic leather supplier.
Where is WINIW located?
WINIW's current website lists its business location in Jinjiang, Fujian Province, China. Buyers should use current registration and commercial documents to confirm the legal entity and address used for a transaction.
Is WINIW a synthetic leather manufacturer or supplier?
WINIW presents itself as a synthetic leather company involved in material development, production and sales. For formal qualification, request the factory list, manufacturing relationship and process scope applicable to the exact material you plan to purchase.
Which synthetic leather materials does WINIW offer?
The current website covers microfiber leather, microfiber suede, PU leather, PVC leather, silicone leather and synthetic chamois. Available constructions, specifications and performance options depend on the proposed material and project.
Can WINIW customize color, grain and material construction?
WINIW's current site offers custom color, texture or grain, gloss and other material options. Send a reference sample, target specification, application and quantity so feasibility, sample terms and acceptance standards can be confirmed.
How can I verify WINIW's production capacity?
Ask for the applicable factory, production line, process, material-specific capacity, current load and audit evidence. Capacity figures should state the unit and period and should be tied to the supply route proposed for your order.
What is the difference between a company certificate and a product test report?
A company or quality-system certificate applies to the organization and scope named on it. A product test report covers the identified sample and test conditions. Neither should be assumed to prove claims outside its stated scope.
What should I send to begin a synthetic leather project with WINIW?
Send the application, current material or TDS, target thickness and width, backing, color, surface, processing method, required tests, trial or annual quantity, destination market and timeline. This gives the team a clearer basis for sample matching and quotation.
