What to Inspect Before Importing Iranian Travertine and Marble Slabs

Use this pre-shipment checklist for Iranian travertine and marble slabs: dimensions, shade variation, finishing, crates and inspection evidence.

Natural stone can look excellent in a showroom sample and still disappoint when a full shipment reaches a project site. Slab thickness, shade consistency, filled voids, finish quality, breakage and crate design can all affect whether the material is usable. Importers buying Iranian travertine and marble therefore need more than photographs and a unit price. A pre-shipment inspection is most effective when supplier and buyer agree on measurable acceptance criteria before production or selection begins. Identify exactly what is being purchased State the commercial stone name, geological classification where important, quarry or material source if represented, block or batch reference, dimensions, nominal thickness and required finish. Natural stone often has visible variations in veining and color. Buyers should specify the acceptable range using approved reference samples or a photo standard rather than demanding impossible uniformity. For large projects, define whether multiple lots must match. If color grouping matters, ask the supplier to photograph each batch under consistent lighting before crating. Inspect thickness, dimensions and finish A stone inspection plan should include a sampling method for measuring length, width, thickness and squareness. Check polish or honed consistency, edge quality, surface scratches and visible repairs. For filled travertine, specify acceptable fill color, adhesion and defect limits. Do not simply write “first quality.” The meaning of this term varies by vendor. Use tolerances and reference images wherever possible. Understand application-related tests Requirements differ for wall cladding, interior flooring, exterior paving and countertops. Depending on use, buyers may need evidence for water absorption, flexural strength, abrasion resistance, slip resistance, freeze-thaw performance or other characteristics. Ask a qualified designer or testing laboratory which methods and thresholds apply to the project's jurisdiction and application. A generic quarry brochure is not a substitute for a material-specific test report relevant to the intended use. Inspect slabs before they disappear into crates Request photos or third-party inspection of the full spread of slabs before packing. Record slab IDs, count, dimensions and apparent defects. A photographic map helps identify which slabs came from which lot and makes later disputes easier to resolve. Inspect the crate system for proper bracing, moisture exposure, forklift access and load distribution. Check that packing lists correspond to crate markings and that the logistics provider can handle the gross dimensions and weight. Compare quotes on usable square meters A low price per square meter can be offset by greater breakage, excessive trimming or a high rejection rate. Estimate delivered usable area after agreed tolerances and reasonable fabrication waste. Do not rely on a single visual sample to predict a shipment's yield. Specify whether prices refer to blocks, uncut slabs, calibrated slabs or finished tiles. These products have different processing and transport economics. Include inspection, packing, freight and destination handling in a comparable landed-cost model. Set the claim procedure before dispatch Agree on inspection timing, photo evidence, independent inspector choice, acceptable defects and a claims deadline. If breakage occurs during transit, responsibility depends on the contract, cargo insurance and applicable delivery terms. The supplier and buyer should not assume an Incoterm alone settles all quality claims. You can discover stone-related categories through ASL Market's Iranian wholesale sourcing section and request quotations using clear dimensions, finish and shipping details. Frequently asked questions Can photos replace an inspection? Photos are helpful but may not reveal thickness variation, hidden repairs or inconsistent surface finish. Should every slab be identical? Natural stone varies. Define the acceptable shade and veining range with agreed reference samples. What should the packing list include? Crate identification, slab counts, dimensions, material description and gross/net weights as relevant.
