Granite Block Logistics & Export Aggregation Service
The Opportunity
Tamil Nadu's state-owned granite quarries (TAMIN) are issuing tenders for dimensional black granite block sales, indicating significant production capacity but fragmented buyer access. Small contractors and international buyers face barriers to aggregating bulk orders from multiple quarries. A service firm can bridge quarry suppliers with end-buyers (construction firms, exporters, fabricators) to capture margin on logistics, quality certification, and buyer-seller matching.
Market Size
₹800–1,200 crore annual granite export market from Tamil Nadu; domestic dimension stone market estimated ₹2,500+ crore. TAMIN alone operates 3+ major quarries with consistent tender cycles.
Business Model
Become an aggregator and logistics partner: (1) Win tender contracts from TAMIN quarries, (2) Consolidate dimensional granite blocks across quarries, (3) Arrange transport, certification, and quality inspection, (4) Sell to domestic construction firms, exporters, and international buyers at 8–12% margin.
Procurement margin: 8–12% on aggregate granite block sales (₹5–8 crore annually at scale)Logistics & handling fees: ₹500–800 per ton for transport, sorting, stacking (₹50–80 lakh annually)Export facilitation & documentation: ₹2–5 lakh per international shipment
