India produces some of the world’s most distinctive and commercially important limestone varieties — stones that have defined the architecture of an entire subcontinent for centuries while simultaneously earning recognition in international construction and design markets. From the legendary Kota Stone of Rajasthan to the dramatic Kadappa Black of Andhra Pradesh, Indian limestone offers a range of colours, properties, and applications that few other stone-producing countries can match.

At Nirvan Exports, we export Indian limestone to buyers across the UAE, UK, USA, Australia, Saudi Arabia, Qatar, and Southeast Asia. In this guide, we cover the varieties we supply, their key properties, and the applications that make each one distinctive.

India’s Limestone Belt: Where It Comes From

Indian limestone deposits are distributed across several distinct geological zones. The Rajasthan deposits — primarily Kota district — produce the globally famous Kota Stone in blue-grey and yellow varieties. Andhra Pradesh and Telangana produce the Tandur (Rangareddy), Kadappa (Cuddapah district), and Chittor varieties. Each region’s geological conditions create stone with distinct mineralogy, colour, and physical properties.

Kadappa Black Limestone: India’s Premium Black Stone

Kadappa Black — also known as Cuddapah Black, AP Black Limestone, or Kaddapa Stone — is quarried from the Kadapa (Cuddapah) district of Andhra Pradesh. It occupies a unique position in the Indian stone market: a black limestone that approaches the visual drama of black granite while being somewhat softer and more workable, making it suitable for applications where black granite would be overspecified.

The stone features a deep black to dark-charcoal surface with a fine-grained, dense texture. Unusually for limestone, Kadappa Black accepts a high-quality polish — the polished surface achieves a deep, lustrous black that is visually comparable to polished black slate or certain dark granites. For interior flooring, wall cladding, kitchen countertops, and architectural steps, Kadappa Black provides a premium black aesthetic at more accessible pricing than black granite.

Kadappa Black has been used in traditional South Indian palace architecture and contemporary luxury interiors alike. It is increasingly specified in international projects — particularly in the Middle East and Southeast Asia — where a dramatic black natural stone surface is desired at a competitive price point.

Chittor Black Limestone: Deep South India’s Dark Stone

Chittor Black limestone is quarried in Chittoor district, Andhra Pradesh, and shares the deep black aesthetic of Kadappa Black while having its own distinct geological character. Chittor Black has a particularly compact, dense formation that gives it above-average hardness for a limestone and makes it suitable for floor and countertop applications that a softer limestone could not withstand. The polished Chittor Black surface achieves a deep, rich black tone that looks outstanding against light backgrounds in contemporary interior design.

Where Kadappa Black is more widely known and has a longer export history, Chittor Black is a discovery for many international buyers — offering comparable black limestone aesthetics with slightly different tonal qualities. Some designers prefer Chittor Black’s slightly warmer undertone compared to the cooler, more blue-black of Kadappa.

Kota Stone: India’s Most Trusted Institutional Limestone

We covered Kota Stone in depth in our Kota vs Tandur guide, but it deserves inclusion here for its export significance. Kota Stone — in both Blue (blue-grey) and Yellow (warm golden) varieties — is India’s most widely used commercial and institutional flooring stone and one of its most exported limestone products. Its combination of very low water absorption (1–3%), high compressive strength, and natural anti-skid properties makes it the preferred choice for railway stations, airports, hospitals, courts, and government buildings.

For international buyers, Kota Blue in particular has strong brand recognition — particularly in the UAE, Gulf region, and South Asia — and is a reliable, cost-effective natural stone for large-scale commercial flooring projects.

Tandur Varieties: South India’s Commercial Limestone

The Tandur limestone family — Grey, Yellow, and Blue — from Telangana’s Rangareddy district represents the dominant stone tradition of South India. These stones have floored the homes, temples, and commercial spaces of Hyderabad and Bengaluru for generations. Each variety has its own character:

• Tandur Grey: Professional medium-dark grey, natural cleft texture, anti-skid, ideal for commercial flooring, courtyards, and verandas.
• Tandur Yellow: Warm golden tone, popular in traditional Indian interiors and increasingly in export markets seeking warm-toned natural stone at accessible pricing.
• Tandur Blue: Distinctive steel blue-grey, more refined and contemporary than Tandur Grey, increasingly popular in modern commercial interiors.

Indian Limestone in the Export Market: Practical Information

HS Code and Customs

All Indian limestone exports — Kota Stone, Kadappa Black, Tandur, Chittor — are classified under HS code 2521.00. In most major import markets including the UAE, UK, USA, Australia, and EU countries, no import duty applies to Indian natural limestone under applicable trade frameworks.

Finishes Available

Kota Stone and Tandur varieties are typically supplied in honed, natural, and polished finishes. Kadappa Black and Chittor Black are particularly well-suited to polished finish for interior applications. For outdoor or slip-sensitive applications, natural cleft, sandblasted, or flamed finish is recommended.

Export Formats

Standard tile formats: 60×60cm, 60×30cm, 30×30cm in calibrated thickness. Custom cut-to-size available. Slab format available for countertop applications. Minimum order: 20 MT (approx. 1 × 20ft container).
