Import Black Granite — Buy in Bulk from Supplier in China

Black granite from Quanzhou Haixing Stone Co., Ltd is a dimension stone product quarried in China, supplied as polished slabs measuring 305 x 305 x 10 mm. The stone exhibits a deep black colouration consistent with gabbroic or diabase-type granites common to Fujian province deposits. The polished finish enhances surface reflectivity and reveals the stone's natural crystalline structure. The supplier lists this material for architectural and decorative applications where hardness and abrasion resistance are required.

The 10 mm thickness places this granite in the standard tile/slab category for interior vertical and horizontal surfaces. Black granite of this type typically demonstrates a Mohs hardness of 6-7 and compressive strength exceeding 200 MPa, though buyers should request certified test reports for this specific batch. The polished surface is achieved through mechanical abrasion using progressively finer abrasives, resulting in a gloss reading typically above 90 GU (gloss units) at 60 degrees. Fujian province hosts extensive granite quarrying operations, with Quanzhou serving as a major processing and export hub for stone products.

This material is purchased by importers serving architects, interior designers, and contractors for countertops, flooring, wall cladding, and bathroom installations. The 305 x 305 mm format is a standard modular size that reduces cutting waste and simplifies layout planning. Buyers should confirm water absorption rates, flexural strength, and acid resistance with the supplier, as these properties vary by quarry block and batch. The supplier has not published MOQ, pricing, or lead time details.

Quanzhou Haixing Stone Co., Ltd is located on Baozhou Road in Quanzhou, Fujian Province, postal code 362000, China. The supplier holds a 'harbor' trust tier designation on the platform, which indicates a baseline verification level. The response rate is recorded at 0.00% with an average response time of 0 hours, suggesting the supplier has not engaged with buyer inquiries through the platform's messaging system. This absence of response data is a material consideration for buyers evaluating communication reliability.

The company operates within Quanzhou's established stone processing and trading cluster, one of China's major centres for granite quarrying, cutting, and export. The listing focuses on polished black granite slabs without providing information about quarry ownership, factory capacity, workforce size, annual turnover, or client portfolio. No certifications, quality management systems, or export licences are listed. Buyers should conduct independent due diligence on the company's production capabilities, quality control procedures, and export experience before committing to orders.
