Quartz Composite Kitchen Sink RFQ Checklist for North American Distributors
Quartz composite kitchen sinks are becoming a standard line item for North American distributors, kitchen & bath showrooms, and cabinet makers. Before issuing a request for quotation, it helps to fix the specification points that determine price, tooling, and reorder consistency. This checklist collects the questions our B2B buyers ask most often.
1. Size and Cabinet Fit
Confirm each model's overall dimensions in millimeters and the minimum base cabinet it fits. Common quartz composite sizes include:
- 680 x 460 mm topmount single bowl — compact drop-in for 30 in cabinets
- 780 x 450 mm undermount 50/50 double bowl — balanced layout for 33 in cabinets
- 800 x 500 mm multifunctional single bowl — larger single-bowl prep zone
- 860 x 460 mm undermount 60/40 double bowl — large cleanup-plus-prep layout for 36 in cabinets
- 410 x 410 mm undermount bar sink — wet bar and prep-station add-on
Ask the supplier for the cutout template and faucet-hole layout for every model before sending drawings to your fabricator.
2. Mounting and Countertop Coordination
State the mounting style per model — topmount (drop-in) or undermount — and the countertop materials your projects use. Undermount models need a reveal preference (positive or negative) agreed with the fabrication shop. Mixed assortments often combine topmount models for laminate-oriented programs with undermount models for stone counters.
3. What to Confirm in the RFQ
A complete quartz composite sink RFQ should list:
- Bowl configuration and drain position per model
- Material composition (quartz composite is typically about 80% quartz sand and 20% resin)
- MOQ per model — our standard is 20 pcs per model, with mixed-model assortments negotiable
- Lead time — approximately 35 days after deposit and specification confirmation
- Trade terms — EXW Foshan or FOB Guangzhou
- Payment — T/T 30% deposit, 70% balance before shipment
- Packaging — carton with EPE foam and corner protection, palletized for sea freight
4. Private Label and OEM
If you plan a private-label program, confirm at RFQ stage: carton printing, logo application, barcode labels, and minimum quantities per SKU. Private-label runs normally follow the same MOQ of 20 pcs per model.
