B2B Indian Granite Supplier for Global Importers
India commands the world's most sought-after reserves of geological granite, supplying over 80 distinctive commercial varieties across deep blacks, sparkling galaxies, steel greys, pristine whites, and warm earthy tones. As a dedicated Indian granite supplier and exporter, Indian Stone Inc coordinates direct block extraction and factory processing across South India (Andhra Pradesh, Telangana, Karnataka, Tamil Nadu) and North India (Rajasthan).
Natural Indian granite is prized by international architects, fabricators, and stone merchants for its tight igneous interlocking crystalline structure. With a Mohs mineral hardness of 6 to 7 and compressive strength surpassing 180 MPa, Indian granite exhibits exceptional resistance to scratching, acidic staining, thermal shock, and deep frost spalling. These properties make it the undisputed global standard for kitchen countertop fabrication, high-traffic commercial airport and hotel flooring, exterior ventilated facades, and urban landscape monuments.
By combining modern multi-wire saws, computerized diamond calibrators, and 16-head line-polishing units, we supply granite slabs and tiles with an ultra-flat plane, ±1mm calibration, and mirror-reflectivity ratings of 95+ gloss units.

Granite Surface Finishes for Interior & Exterior Specifiers
- Line Polished (High Gloss 95+): Mirror-reflective smooth finish enhancing mineral depth, contrast, and color vibrancy. Ideal for interior floors, vanities, and kitchen countertops.
- Flamed / Thermal Finish: High-temperature oxygen-acetylene thermal shock induces crystalline spalling, creating a textured, slip-resistant surface tested to R11/R12 ratings for exterior paving, plazas, and swimming pool copings.
- Leathered / River-Washed: Diamond-grit brushes trace the natural mineral veins to produce a velvety, fingerprint-resistant satin texture with tactile relief.
- Honed Finish: Satin-smooth matte surface without specular reflection, engineered for understated contemporary commercial architecture.
- Bush-Hammered: Mechanically dressed with carbide hammers for uniform non-slip pedestrian and municipal walkway surfaces.
Physical Test Performance (ASTM C615 & EN 1469)
ISPM-15 Wooden Crating & Ocean Container Stuffing
Granite export requires extreme diligence in packaging due to the immense weight and structural rigidity of natural stone:
- Certified ISPM-15 Wooden Bundles: Slabs are packed in fumigated, heat-treated pine A-frame bundles. High-tensile steel straps secure the stone slabs firmly against internal timber frames.
- Plastic Barrier & Edge Protectors: Every bundle is protected with heavy poly-sheeting against seawater vapor. Hard plastic corners protect bevels and edges from strap friction.
- Heavy 20ft Container Payload: Slabs are loaded longitudinally and secured with heavy timber beams, wedges, and cross-bracing. Inflatable sea dunnage bags absorb vibration:
• 20mm Slabs: ~400–440 m² per 27 MT payload (~7 bundles)
• 30mm Slabs: ~270–300 m² per 27 MT payload (~6 bundles)
Export Gateways: Shipments sail from Nhava Sheva (JNPT Mumbai), Mundra Port (Gujarat), or Chennai Port, depending on quarry location. We provide full export customs clearance, Bill of Lading, Certificate of Origin, and container sealing photos.
Frequently Asked Questions — Indian Granite Supply
What is the minimum order quantity (MOQ) for granite export?
Our standard commercial MOQ is one 20ft full container load (FCL). However, you can mix 2 to 3 different South Indian or North Indian granite colors within the same container to optimize your inventory.
How do you ensure shade consistency across a large commercial order?
For large project orders, all slabs are processed from consecutive blocks quarried from the exact same pit level. We perform dry-lay shade sorting in our factory yard and number every slab sequentially so your installation team can lay the stone in seamless color progression.
Can you fabricate prefabricated countertops with edge profiles?
Yes. We supply prefabricated kitchen countertops, bathroom vanities, and island tops with eased, pencil round, full bullnose, or mitered waterfall edges, including cutouts for undermount sinks and faucet drillings according to your CAD drawings.
How long does sea transit take from India?
Transit times vary by port: Jebel Ali (UAE) takes 4–6 days; European main ports (Rotterdam, Antwerp, Felixstowe) take 22–28 days; US East Coast (New York, Savannah) takes 28–34 days; and US West Coast (Long Beach) takes 26–32 days.
