| 1 |
Product and Material Fit |
Confirm whether the supplier produces the required panel type, such as PVC, WPC, MDF, fiber cement, calcium silicate, aluminum, acoustic, or sandwich panels.
|
Match the panel core, surface finish, moisture resistance, impact resistance, and installation method with the project environment.
|
Send drawings, intended-use conditions, panel dimensions, color requirements, and installation details before requesting a quotation.
|
Technical data sheet, product cross-section, sample, raw-material specification, and installation manual.
|
| 2 |
Factory Capability |
Check whether the supplier operates its own production facility and has suitable cutting, laminating, coating, molding, printing, or panel-forming equipment.
|
A suitable factory should demonstrate stable production capacity, documented process control, traceable batches, and the ability to maintain consistent dimensions and finishes.
|
Request a recent factory video, production-flow diagram, equipment list, factory audit, or third-party inspection.
|
Business license, factory address, production photographs, equipment list, and audit report.
|
| 3 |
Dimensional Accuracy |
Verify panel length, width, thickness, flatness, squareness, edge quality, tongue-and-groove fit, and decorative alignment.
|
Use the agreed product drawing and approved sample as the inspection reference. Tolerances must be written into the purchase contract rather than left as verbal promises.
|
Approve a golden sample and define inspection tolerances for each critical dimension before mass production.
|
Signed drawing, inspection checklist, sample approval record, and pre-shipment inspection report.
|
| 4 |
Fire and Safety Performance |
Determine the fire-performance requirement applicable to the destination market and the building type.
|
Common references include EN 13501-1 in Europe and ASTM E84 in North America. The exact classification depends on the tested product construction and installation method.
|
Specify the required test method and classification in the request for quotation. Do not accept a general statement such as “fireproof” without a report.
|
Laboratory test report, product identification, test standard, test date, and scope of application.
|
| 5 |
Moisture, Durability, and Indoor Use |
Assess water absorption, swelling, mold resistance, UV resistance, scratch resistance, chemical resistance, and suitability for kitchens, bathrooms, offices, or exterior areas.
|
Performance requirements vary by substrate and application. Moisture-sensitive panels should not be selected for wet areas without relevant test evidence.
|
Describe the installation location and expected service conditions, then compare test results rather than relying on product names.
|
Water-absorption data, humidity-cycle results, surface-resistance test, warranty terms, and care instructions.
|
| 6 |
Quality Management and Compliance |
Check the supplier’s quality-management system, product traceability, corrective-action process, and control of nonconforming goods.
|
ISO 9001 certification can indicate a quality-management system, but it does not by itself prove that every panel meets a specific performance requirement.
|
Verify certificates through the issuing organization when possible and confirm that the certificate holder and factory address match the supplier information.
|
Valid certificate, scope statement, internal inspection records, batch records, and corrective-action samples.
|
| 7 |
MOQ, Pricing, and Total Cost |
Compare minimum order quantity, sample cost, tooling cost, packaging cost, inland freight, export charges, and destination delivery terms.
|
The lowest unit price may not be the lowest landed cost. Custom colors, special profiles, and small orders commonly increase tooling or setup charges.
|
Request a quotation under the same Incoterm, currency, specification, packing method, and quantity for a fair comparison.
|
Itemized quotation, pro forma invoice, tooling quotation, packing list, and Incoterm confirmation.
|
| 8 |
Lead Time and Production Planning |
Confirm sample lead time, tooling lead time, production lead time, inspection schedule, port cut-off date, and shipping route.
|
Lead time should be linked to order quantity, customization level, raw-material availability, and approval of artwork or samples.
|
Add milestone dates and delay-notification requirements to the purchase order. Avoid booking final transportation before production status is confirmed.
|
Production schedule, order milestone plan, shipment history, and written delivery commitment.
|
| 9 |
Packaging and International Logistics |
Evaluate edge protection, moisture protection, pallet strength, carton markings, container utilization, and loading method.
|
Packaging should protect decorative surfaces and panel edges during handling, long-distance transport, and changes in humidity.
|
Approve packaging photographs or a packing sample. Define carton labels, pallet dimensions, stacking limits, and spare-panel requirements.
|
Packing specification, loading photographs, carton dimensions, gross weight, packing list, and shipping documents.
|
| 10 |
Contract, Inspection, and After-Sales Support |
Review payment terms, warranty coverage, claims procedure, replacement policy, dispute resolution, and responsibilities for defective or damaged goods.
|
A clear contract should define specifications, approved samples, tolerances, inspection rights, delivery terms, documents, and remedies for nonconformity.
|
Use a pre-shipment inspection before balance payment where commercially appropriate, and retain photos, test reports, and batch records.
|
Sales contract, quality clause, warranty statement, inspection report, claim form, and after-sales contact details.
