Import Blue Limestone — Buy in Bulk from Supplier in China

This Blue limestone from Jining Zhidian Stone Co., Ltd is a sedimentary carbonate stone quarried in Shandong Province, China, offered in tile, slab, and engineered formats for construction and landscaping use. The stone's blue-grey colouration derives from variable clay and organic content during formation, with hardness and density dependent on specific quarry bed and extraction depth. Jining Zhidian operates from Jiaxiang Industrial Zone #21 in Jining, Shandong, though the listing does not specify which quarry or geological formation supplies this particular material, and buyers should request source quarry documentation for consistency on repeat orders.

Blue limestone typically falls in the 3-4 range on the Mohs hardness scale, with bulk density between 2,600 and 2,800 kg/m³ and water absorption of 0.5-3.0% depending on porosity and finish. The supplier mentions polished, honed, and natural finishes, each affecting slip resistance, maintenance requirements, and suitability for wet or high-traffic areas. Polished finishes reduce porosity surface exposure but can become slippery when wet; honed surfaces offer better traction for flooring. The listing's 'engineering stone' reference may indicate cut-to-size dimensional stone or reconstructed limestone composite; clarify this with the supplier, as true dimensional limestone and reconstructed stone carry different structural properties and installation requirements.

Applications span exterior paving, wall cladding, interior flooring, stair treads, pool surrounds, and landscape hardscaping. The stone's frost resistance is not stated but matters critically for exterior use in temperate climates, freeze-thaw cycles can cause spalling in porous or incorrectly sealed limestone. Buyers should request test data for compressive strength, flexural strength, and water absorption per GB/T 9966 or EN 1341 standards. Trade terms mentioned are FOB and CIF, with flexible MOQ, though exact minimum quantities, lead times, and price bands are absent from the data and require direct negotiation with Jining Zhidian.

Jining Zhidian Stone Co., Ltd is located at Jiaxiang Industrial Zone #21, Jining, Shandong 272400, China, placing it within a region with established stone processing infrastructure. The supplier holds a 'harbor' trust tier and an 'imported' supplier tier, indicating some level of platform engagement, though the response rate shows 0.00% with zero average response hours. This lack of recent messaging activity means buyers cannot rely on platform-tracked responsiveness and should establish direct communication channels, including phone and email verification, before committing to large orders.

The company's product range centres on blue limestone in multiple formats, suggesting either direct quarry ownership or strong contractual sourcing relationships in Shandong's stone belt. No factory audit results, quarry ownership certificates, or export license details are present in the source data. The listing mentions product certification without specifying standards or issuing bodies, buyers should request current certificates for CE marking (if supplying Europe), ASTM compliance (US market), or equivalent national standards. Specific machinery, gang saw capacity, or monthly processing volume are not disclosed and should be verified if project scale demands tight delivery schedules.
