Import China Black Granite — Buy in Bulk from Supplier in China

China black granite from Qingdao Dongxin Stone Co., Ltd. is a natural stone quarried in Shandong province, featuring a dense, fine-grained structure with minimal veining and a consistent deep black hue. The material is available in standard slab dimensions of 2400mm x 1200mm x 20mm, with custom thicknesses ranging from 15mm to 30mm upon request. Surface finishes include polished, honed, and flamed, each offering distinct tactile and visual properties suited to architectural applications.

The granite meets standard commercial grade classifications for igneous stone, with a compressive strength typically exceeding 130 MPa and a water absorption rate below 0.3%, consistent with ASTM C615 specifications. It contains primarily plagioclase, biotite, and quartz, with trace iron oxides contributing to its deep coloration. While the listing claims ISO and SGS certification, no certificate numbers or test reports are provided; buyers should request documented compliance with EN 1469 or ASTM C616 for structural use.

This material is commonly specified for high-end countertops, exterior cladding, flooring in commercial lobbies, and memorial monuments due to its durability and aesthetic consistency. Buyers include architectural firms, luxury residential developers, and landscape contractors sourcing for projects in Europe, North America, and the Middle East. Trade terms are typically FOB Qingdao Port, with minimum order quantities negotiated per shipment size. Packaging is in wooden crates with foam padding, and export documentation includes phytosanitary certificates for stone shipments.
