Approving a kitchen sink sample is not only a visual check. For importers, wholesalers and distributors, the approved sample becomes the reference for mass production, packaging, installation communication and after-sales handling. Before approval, the buyer should record what has been confirmed, what still needs factory confirmation, and which details must match the final order.
1. Confirm the Exact Model and Dimensions
Start with the model number. Similar sink photos can still refer to different models, and a small naming mistake can create confusion later in production. The approval record should show the exact model number, overall dimensions, bowl dimensions, depth, drain hole position and installation type used for the sample.
This article does not set fixed dimensions for every sink model. The correct figures should come from the actual sample, order sheet, product drawing or confirmed model information. The important point is that the buyer and supplier use the same reference before moving to mass production.
2. Check the Material and Thickness Requirement
The sample should match the material and thickness requirement agreed for the order. If the buyer has a specific requirement, it should be written in the sample approval record instead of being left as a verbal note or message thread.
Do not treat a general product description as a production standard. The production team, buyer and sales contact should all be working from the same confirmed requirement.
3. Review the Surface Finish Under Normal Lighting
Surface review should be done under normal lighting, not only from edited catalogue photos. Check the visible finish, grain direction, color consistency, rim, corners, edge treatment and handling marks. The details to check are different for pressed sinks and handmade sinks, so the sample record should identify the construction type clearly.
For a pressed sink, check the consistency of the formed bowl, rim, corners and visible surface. The bowl is formed from one sheet, so there is no welded basin joint to inspect.
For a handmade sink, also check the welded joints and the quality and consistency of the finishing around the joined areas. These checks should be written as normal construction-specific inspection points, not as product defects.
No stainless steel sink should be described as impossible to scratch. A better approval process is to confirm the expected finish, keep real reference photos, and prepare clear handling notes for the buyer’s sales channel.
4. Confirm the Drain Hole, Overflow and Accessories
Accessories should be checked against the real order, not against every item shown in a sample photo. Confirm the drain hole size, overflow position if applicable, drainage kit, bottom grid, colander, cutting board and any other approved accessories only when they are part of the actual order.
If an accessory is optional, label it as optional in the approval record. This reduces the risk of missing-part complaints after delivery.

5. Check Installation Compatibility
Sample approval should include the installation method discussed for the target market, such as topmount, undermount or flush mount. Buyers should also confirm countertop cut-out needs and cabinet clearance with their local installation team.
This is a compatibility check, not an installation standard. If the project has strict installation requirements, the buyer should confirm them with the installer or project team before approving the sample.
6. Approve the Packaging, Labels and Carton Marks
Packaging is part of the product experience for business buyers. Confirm the individual packaging, protective materials, outer carton, label, barcode, carton marks, accessory placement and model identification used for the order.
Do not invent packaging test results or transport damage rates. If packaging strength or special carton requirements matter for the buyer’s market, they should be confirmed as a separate order requirement.
7. Record the Approved Sample Properly
A useful sample approval record should include sample photos, model number, confirmed dimensions, finish, accessories, packaging details, approval date, buyer comments and production reference notes. This record helps both sides avoid relying on memory when the order moves from sample to production.
For private-label work, the record should also identify which label, carton mark or packaging detail belongs to the buyer’s own requirement.
8. Use the Approved Sample as a Mass-Production Reference
After approval, the sample should be used as a reference for pre-production checking, production communication and pre-shipment photo review. It does not replace factory quality control, and it should not be described as a certification or test report.
The practical goal is simple: the sink shipped in bulk should match the approved model and order record as closely as the confirmed production process allows.

Questions Importers Often Ask
Is sample approval only about checking appearance?
No. Appearance matters, but a B2B sample should also confirm model information, dimensions, finish, accessories, packaging and production reference details.
Do pressed and handmade sinks require the same surface checks?
No. A pressed sink is formed from one sheet, so the inspection focuses on the formed bowl, rim, corners and visible finish. A handmade sink also requires inspection of the welded joints and the finish around joined areas.
Should every accessory in a sample photo be included in the order?
No. Accessories should be listed clearly as included or optional. Buyers should not assume that every item in a photo is part of the order.
Can a sample approval record replace certification or testing?
No. A sample approval record is a production and communication reference. Certification or testing claims require separate verified documents.
What should buyers send when asking for a quotation?
Send the model number, required dimensions if already confirmed, target quantity, packaging needs, accessory requirements and any sample approval points that must be checked.
For model selection, buyers can review press stainless steel sink models and handmade stainless steel sink models. Private-label buyers can also review private-label kitchen sink supply.
