Use this procurement checklist to confirm sink dimensions, finish, accessories and packaging before approving a production sample.
Bring a drawing, reference model or physical sample to the first discussion, and describe the target market and use. If the drawing and sample disagree, confirm which revision takes precedence.
Confirm installation dimensions and construction
List outside dimensions, bowl depth, countertop cutout, cabinet clearance, mounting type, material and thickness. Mark changes and ask the supplier to show the drawing revision and critical tolerances.
Approve color, texture and matching parts
Compare the finish sample with the worktop and faucet in the same light. Confirm the part numbers and fit of the drain kit, basket, cutting board and any other accessories.
Record the approved sample and packing details
Keep the sample reference, photos, specifications and changes. Confirm branding, labels, cartons and included documentation, then use the approved checklist for the first production lot. See workshop packing footage and submit the OEM sample brief.
