Choosing between faucet manufacturers in China requires comparable evidence for the product you intend to buy. This checklist is written for importers, distributors, brands and project buyers comparing suppliers. It is a sourcing guide from VIGA, not a ranking of competing manufacturers.
Use it to build a shortlist, compare like-for-like quotations and decide what must be verified before a purchase order. For VIGA’s company and product introduction, start at our faucet factory homepage.
1. Define the product before building a shortlist
Specify the intended installation, dimensions, connection requirements, material, finish, quantities and destination market. Identify which components and accessories must be included. A low quote for a different configuration is not a useful benchmark.

2. Verify the contracting entity and production responsibilities
Ask who will issue the quotation and invoice, who manufactures the product, and which site will carry out the agreed work. Clarify any external processing or subcontracted assembly. Confirm the route for technical questions, inspection access and after-sales support.
A manufacturer and a trading company can offer different arrangements. Neither label alone guarantees a lower total cost or better quality. Compare the actual responsibilities, traceability and response process offered for your order.
3. Compare capability with evidence
- Product fit: request a model list, drawings and component specifications matching your brief.
- Production scope: review current workshop information and ask who controls each important operation.
- Quality records: request a proposed inspection plan and examples of the records supplied with orders.
- Documentation: check whether the documents offered cover the exact model and destination requirements you specified.
- Capacity and timing: ask for the proposed schedule, dependencies and how delays or specification changes are communicated.

For a discussion with VIGA, use the factory production and quality review to prepare questions. Factory images introduce the site; they do not replace current records or an order-specific inspection agreement.
4. Build a like-for-like quotation comparison
Use one comparison sheet for every supplier, with these fields:
- Model, drawing revision, finish and included components.
- Quantity and minimum order by model and finish.
- Unit price, currency and quotation validity.
- Sample, development, tooling and packaging charges.
- Inspection arrangements and any third-party costs.
- Delivery terms, named destination and transport responsibilities.
- Payment milestones, lead-time starting point and proposed shipment window.
- Spare parts, warranty terms and the procedure for handling defects.
Flag missing information rather than assuming it is included. Review the total quoted scope and the cost of resolving problems, alongside the unit price.
5. Use samples and documents to resolve uncertainties
Check the sample against the agreed drawing, finish reference, included components and functional requirements. Record any changes before approving production. Confirm whether supporting documents correspond to the supplied configuration and remain valid for the intended use.
You can review VIGA’s published certificate documents, then request confirmation of the relevant model and scope. A general claim such as “certified quality” is not a substitute for this check.
6. Agree the next step with the shortlisted supplier
For an OEM or ODM project, use our custom faucet project guide to clarify design responsibilities, sample approval and change control. Put the final specification, inspection arrangement and commercial terms into the purchase agreement.
To include VIGA in your shortlist, send us your sourcing brief with model references, quantities by finish, destination market and requested timing. Ask for a quotation and supporting information against the same brief used for other suppliers.
