Import Black Engineered Quartz Stone Slabs — Buy in wholesale FOB from Supplier in China

Black engineered quartz stone slabs from Lanhe Stone Co.,Ltd. consist of 93% natural quartz powder bound with 7% unsaturated polyester resin and pigment additives, a composition that yields a Mohs hardness of approximately 7 and excellent resistance to scratching and staining. The standard slab dimensions are 3000 x 1400/1600 mm or 3200 x 1600 mm, with thickness options of 12 mm, 15 mm, 18 mm, 20 mm, and 30 mm. Cut-to-size pieces, countertops, vanity tops, and island configurations are available with customised dimensions on request.

The resin-bonded quartz matrix provides uniform colour distribution and eliminates the natural veining variations found in quarried stone, making it suitable for large-surface installations requiring visual consistency. Surface finishes include polished, honed, antique, and abrasive blasting, each altering the aesthetic and slip-resistance properties. Standard industry practice for engineered quartz requires less than 0.5% water absorption and flexural strength above 25 MPa, though buyers should request test certificates for the specific batch. Pigment additives determine colour variants including white, black, grey, red, yellow, and pink.

These slabs serve kitchen countertops, bathroom vanities, worktops, backsplashes, shower surrounds, wall cladding, and flooring in both residential and commercial projects. The 12 mm and 15 mm thicknesses suit vertical cladding and light-duty horizontal surfaces, while 20 mm and 30 mm thicknesses bear the load of countertop overhangs and high-traffic areas. A standard 20-foot container accommodates 170 slabs at 12 mm, 140 at 15 mm, 105 at 20 mm, or 70 at 30 mm thickness. Buyers should confirm MOQ, lead time, and Incoterms directly with Lanhe Stone Co.,Ltd., as these are not stated in the source data.

Lanhe Stone Co.,Ltd. maintains its registered office at B16F, Haifu Mansion, Sishui Road, Xiamen, Fujian Province, 361006, China, a location within one of the country's principal stone processing and export corridors. The supplier holds a Harbor trust tier classification on the marketplace, indicating a baseline verification level, though the response rate displays as 0.00% with an average response time of zero hours, which suggests either a new listing, a technical reporting issue, or limited engagement history. Buyers should note this signal and test responsiveness directly before committing to orders.

The listing emphasises that Lanhe operates its own factory, specialises in stone exports, accepts customised sizing, and targets short delivery times. The company serves markets across North America, South America, Europe, Australia, the Middle East, Africa, and Southeast Asia. No information is provided about factory size, annual output, workforce numbers, years in operation, ISO or environmental certifications, or named client references. Buyers should request factory audit reports, quality management system documentation, and export licence verification during due diligence.
