What should I check when inspecting Iranian limestone blocks for export?

Check block dimensions against your order, color consistency, absence of structural cracks, density and soundness (tap test), surface quality, and that the blocks match the grade specified in your proforma invoice.

How is crystal stone different from regular marble for inspection purposes?

Crystal stone (like Neyriz) has a crystalline structure that can contain internal voids or fractures not visible on the surface. The tap test is especially important — a dull sound may indicate internal issues that reduce yield.

Can I request photos of my stone blocks before they are loaded?

Yes. A reputable supplier provides photos of each block from multiple angles before loading. StoneBuySell includes photos and a video of the loading process with every shipment.

Should I hire a third-party inspection agency for Iranian stone shipments?

For high-value shipments or first-time orders, a third-party inspection is recommended. Agencies like SGS or Bureau Veritas can inspect blocks at the quarry or processing facility in Iran before loading.

What defects are acceptable in natural stone blocks?

Minor surface fissures, color variation within the grade specification, and small mineral inclusions are normal in natural stone. Structural cracks through the block, off-spec dimensions, and grade mismatches are rejectable.

How does quality inspection affect my insurance coverage?

Pre-shipment inspection photos and reports document the condition of goods before loading, which is critical if you need to file an insurance claim for transit damage. Always keep inspection records.
