Finding a low-price supplier is easy; finding a reliable long-term manufacturing partner requires more careful evaluation.

1. Request Physical Samples

Check the actual stone surface, thickness, weight, color variation, and panel construction before ordering in bulk.

2. Evaluate Production Capacity

Confirm that the factory can support your expected monthly or annual volume, particularly if you supply large construction projects.

3. Check Color and Size Consistency

Natural stone naturally varies, but a professional manufacturer should have effective sorting and grading procedures to keep batches within the agreed specifications.

4. Review Packaging

International shipments require strong packaging. Ask about pallets, wooden crates, corner protection, internal cushioning, and container loading procedures.

5. Ask About Customization

For established distributors, useful options may include:

• Custom panel dimensions

• Custom colors

• Custom textures

• Corner pieces

• OEM labels

• Retail packaging

6. Verify Export Experience

An experienced exporter should understand international shipping documentation, container loading, quality inspection, and delivery schedules.

7. Compare Landed Cost

Don't compare suppliers based only on the factory quotation. Calculate:

Product Cost + Packaging + Inland Freight + Ocean Freight + Import Costs + Handling

The supplier with the lowest unit price may not always provide the lowest total landed cost.
