| Supplier 1 | Request a recent test report for the offered stone lot. Relevant ASTM methods include C97/C97M for absorption and bulk specific gravity, C170/C170M for compressive strength, and C880/C880M for flexural strength. | Quote required; compare the same product form, thickness, finish, quantity, and delivery term. | Confirm export packing, shipping documents, port of loading, and proposed Incoterm in writing. | Not independently verified. |
| Supplier 2 | Ask for slab or tile dimensions, thickness tolerances, finish details, and photos of the actual production lot; verify test reports against the quoted material. | Quote required; request separate itemization for stone, processing, packing, and freight where applicable. | Confirm whether fumigated or otherwise compliant wooden packing is available when required by the destination market. | Not independently verified. |
| Supplier 3 | Request samples and written acceptance criteria for color range, veining, surface finish, edge quality, and allowable natural variation. | Quote required; confirm currency, validity period, minimum order quantity, and whether the price is per square metre, slab, or other unit. | Confirm availability of a packing list, commercial invoice, and bill of lading or other agreed transport document. | Not independently verified. |
| Supplier 4 | For dimension stone, ask whether the product is specified against ASTM C615/C615M and obtain the applicable product specification and test documentation. | Quote required; compare like-for-like finish, thickness, dimensions, edge processing, and order volume. | Request estimated production time, shipment schedule, and details of how delays or damaged cargo are handled. | Not independently verified. |
| Supplier 5 | Check whether the supplier can provide lot identification and inspection records linking the delivered material to the approved sample. | Quote required; clarify taxes, duties, inland transport, ocean freight, and insurance inclusions or exclusions. | Confirm the offered Incoterm and named place or port; do not compare offers with different delivery responsibilities as equivalent. | Not independently verified. |
| Supplier 6 | Request inspection criteria for flatness, squareness, calibration, surface defects, and finish consistency, tailored to the intended application. | Quote required; ask whether sample, inspection, and special packing costs are included or charged separately. | Ask for loading photos, crate or bundle counts, gross and net weights, and container-loading records if available. | Not independently verified. |
| Supplier 7 | For relevant applications, request test results for the properties specified in the project documents; use the applicable standard and acceptance limits agreed by buyer and seller. | Quote required; obtain a written quotation with product description, quantity, unit, payment terms, and quotation validity. | Confirm communication contact, document turnaround, shipment tracking arrangements, and post-shipment support. | Not independently verified. |
| Supplier 8 | Request a pre-shipment inspection or agree on an independent inspection procedure, sampling method, and acceptance criteria before production. | Quote required; check whether volume discounts or mixed-size loading are offered for the specific order. | Verify destination-specific document requirements with the buyer's customs broker before shipment. | Not independently verified. |
| Supplier 9 | Compare approved control samples with production material under consistent lighting; record agreed limits for natural color and pattern variation. | Quote required; confirm payment schedule, deposit terms, balance timing, and any charges for changes or cancellations. | Confirm the supplier's responsibility for export clearance and the specific shipping documents included in the offer. | Not independently verified. |
| Supplier 10 | Require written product identification, agreed inspection standards, and supporting quality records before approving bulk production. | Quote required; evaluate landed cost using the same order specification, delivery term, and destination for every offer. | Confirm the proposed shipping route, estimated transit time, packing method, and process for reporting transit damage. | Not independently verified. |
