Oriental white marble

Oriental White Marble, often referred to as 'Chinese Carrara,' is prized for its milky white base and delicate grey veining. When sourcing, you must prioritize Water Absorption Rate (ideally <0.20%) to ensure stain resistance and Compressive Strength (typically >90 MPa) for structural durability. Ensure the Mohs Hardness is between 3 and 4, making it suitable for indoor flooring and wall cladding, though it requires professional sealing for high-moisture areas.

Natural stone inherently varies. To manage this, request Dry-Lay Photos where the supplier lays out the cut tiles in sequence to check the vein flow. Specify the Grade (A, AB, or B); Grade A features a pure white background with minimal crystal lines or black spots. Always demand a Range Sample consisting of 3-5 pieces that represent the maximum allowable variation in color and pattern.

Standard finishes include Polished (high gloss >85 degrees), Honed (matte), and Brushed. For architectural projects, verify the Thickness Tolerance, which should be ±0.5mm for tiles and ±1mm for slabs. Ensure the edges are processed according to your needs, whether Eased, Bullnose, or Mitered, to prevent chipping during installation.

Suppliers should provide ASTM (American Society for Testing and Materials) or EN (European Standard) test reports. Key certifications include ISO 9001 for quality management and CE Marking for the European market. Additionally, verify that the stone meets Radioactivity Safety Standards (Class A), ensuring it is safe for unrestricted use in residential and commercial interiors.

The biggest risk is breakage during transit. Ensure the supplier uses fumigated solid wooden crates with internal foam protection and plastic wrapping to prevent moisture staining. For sea freight, ensure the containers are balanced and braced to prevent shifting. It is highly recommended to purchase All-Risk Marine Insurance covering 110% of the invoice value.

Utilize the Secured Trading Services offered on Made-in-China.com to protect your payment until delivery is confirmed. When negotiating, clarify the Incoterms (FOB or CIF) and insist on a Third-Party Pre-shipment Inspection (PSI). A common strategy is to link the final 30% payment to the successful issuance of a Clean Bill of Lading and a satisfactory inspection report.

Marble is extremely heavy; therefore, Weight Limits per container vary by country (e.g., the US has strict road weight limits that may restrict a 20ft container to roughly 17-21 tons). Work with a freight forwarder experienced in Heavy Cargo to avoid 'Overweight' surcharges at the destination port. Always confirm the Harmonized System (HS) Code (typically 680221) to calculate accurate import duties.
