Faucet Surface Treatments: An OEM Finish Approval Checklist

A finish name is only the starting point of a faucet specification. For an OEM order, the buyer and supplier need a shared reference for appearance, a defined approval process and a record of what will be delivered. This guide focuses on those purchasing decisions for kitchen and bathroom faucets.

Separate the appearance reference from the technical specification

Terms such as chrome, brushed nickel, matte black and gold describe a commercial appearance, but a purchase order should explain what the supplier means by the selected option. Ask for the proposed substrate, surface process and finish reference for the exact model. Record any parts that use a different material or process.

A photograph is useful for shortlisting. Before production approval, agree how physical samples will be viewed and compared. Handle shape, brushing direction, gloss and the relationship between the faucet body and accessories can all affect whether the assembled set meets the design brief.

Build a finish approval sheet

Review evidence without turning appearance into a performance claim

Colour and shine do not establish a service life or a corrosion-resistance rating. When a project requires performance evidence, put the requested method and acceptance criteria in the specification and ask the supplier to identify the tested sample. Review the report date, sample description, issuing organisation and any limitations.

If an offered test report describes a different finish or product configuration, record that gap and resolve it before approving the order. Avoid treating a photograph of a test chamber, an unlabelled sample or a general catalogue statement as evidence for a specific production lot.

Approve the finish on the complete set

Place the faucet next to the intended drain, handles and other visible accessories. Record which items are supplied together and which will come from other vendors. Agree who approves the final combination so that a faucet sample does not accidentally become approval for an entire bathroom package.

For repeat purchases, retain the approved reference and its identifier. A change in model, component, finish process or reference sample should lead to a documented review, with the purchase order stating which version applies.

Questions to settle before placing an OEM order

Can a colour code replace a physical sample?

Use the code to communicate the target, then agree the sample and comparison method with the supplier. Record the approved reference in the order rather than relying on a message thread alone.

Should the same finish be assumed across all models?

Request confirmation for each ordered model and exposed component. List any agreed exceptions on the finish sheet.

What should accompany a request for quotation?

Send the model or drawing, finish reference, quantities by variant, destination, requested evidence and packaging requirements. Mark unresolved items clearly so they can be priced and reviewed.

For a VIGA enquiry, use the OEM/ODM project page and contact form to share your specification. Confirm available finishes and supporting documents for the selected model during quotation.
