A custom Corian sink request should be made when the project specification, brand program, or buyer documentation clearly requires that material. It should not be used as a general label for all solid surface basins.
Use the following points as a working checklist rather than a broad product introduction. The details are written for B2B buyers who need to coordinate quotations, samples, project documents, and repeat orders with fewer surprises.
Request Corian when the specification requires it
Some hotel, commercial, or private-label programs may name Corian in their material documents. In that case, buyers should send the specification instead of only asking for a general price. QINGDA can review the request for selected custom projects through Corian Material Option.
For a purchasing team, this point should be recorded in a shared specification file rather than left in a chat message. Include the model number, drawing version, requested finish, quantity, packing note, and the person who approved the detail. That record helps the cabinet factory, project contractor, distributor, and supplier work from the same information when the order moves from quotation to sample and then to bulk production.
During sample review, check the physical product against the drawing and the quotation line by line. Measure the main dimensions, inspect the surface finish under normal light, test the drain and faucet hole positions against the cabinet plan, and take clear photos for the order file. A sample should not be approved only because the general appearance looks acceptable.
Confirm model suitability first
Not every basin shape, size, or structure should be assumed suitable before review. The selected model, bowl shape, edge design, size, finish, and production method should be checked. Start from QINGDA solid surface wash basin models or a custom drawing, then ask whether the material request can be evaluated.
Buyers should also ask what information is still missing before the supplier can quote accurately. Missing details often include faucet type, overflow requirement, cabinet drawing, carton mark, delivery window, or the exact material wording needed for the project file. Clarifying these items early makes the quotation more useful and reduces the chance of rework after sample approval.
For bulk orders, the same detail should be repeated consistently. Ask how the supplier will separate models, mark cartons, protect corners, report inspection results, and communicate shipment readiness. This is especially important when one purchase order includes several sizes or when the products will be installed in different floors, buildings, or room types.
Prepare quantity, finish, and budget information
A material-specific request needs a real quantity range, finish expectation, color requirement, and target budget. Without these details, the supplier cannot judge whether the request is practical for the project. Buyers should also provide the target delivery schedule.
During sample review, check the physical product against the drawing and the quotation line by line. Measure the main dimensions, inspect the surface finish under normal light, test the drain and faucet hole positions against the cabinet plan, and take clear photos for the order file. A sample should not be approved only because the general appearance looks acceptable.
If the buyer is comparing several suppliers, use the same checklist for each one. A supplier who gives a lower unit price but cannot confirm drawings, packing, inspection, or material wording may create extra cost later. A practical comparison should include sample cost, expected lead time, packing method, communication quality, and how clearly the supplier handles changes before production.
Lead time and technical review
Corian material requests may require additional review before quotation and sample planning. Buyers should allow time for model evaluation, material confirmation, drawing review, and sample discussion. If the project timeline is tight, state the installation date at the beginning.
For bulk orders, the same detail should be repeated consistently. Ask how the supplier will separate models, mark cartons, protect corners, report inspection results, and communicate shipment readiness. This is especially important when one purchase order includes several sizes or when the products will be installed in different floors, buildings, or room types.
Keep the material statement consistent through the whole process. Acrylic Solid Surface is the standard material for QINGDA catalog basins. Corian material available upon request should be used only when the buyer has specifically asked for that option and the selected project has been reviewed. This avoids incorrect catalog claims and keeps quotations clear for downstream buyers.
Keep standard material wording in other documents
For normal QINGDA catalog basins, Acrylic Solid Surface remains the standard material. Use Corian only where the buyer has specifically requested and confirmed that option. This avoids describing all QINGDA products as Corian sinks.

How to send the request
Send the model or drawing, size, finish, color, quantity, specification file, packing requirement, and schedule through contact QINGDA. If the project also needs custom dimensions or private-label packing, review Custom Sizes service and OEM and ODM support before finalizing the inquiry.

Final review before sending the inquiry
Before contacting a supplier, prepare a compact inquiry package: selected model or drawing, target size, quantity, application, finish, faucet hole and overflow requirements, packing request, delivery schedule, and any material specification. This gives QINGDA enough information to respond with practical comments instead of a generic reply.
The final check is simple: the product should match the cabinet or project layout, the material wording should be accurate, the packing should fit the delivery plan, and the buyer should know what must be approved before production starts. When these points are clear, a solid surface wash basin order is easier to quote, sample, inspect, and repeat.
