The United States is the deepest countertop market in the world and the most demanding on two specific things: format discipline and documentation. It is comparatively relaxed about origin storytelling and comparatively unforgiving about a bundle that arrives out of sequence.
This page is the reference for US slab distributors, countertop fabricators and importers buying Indian stone.
What the US market actually buys
3 cm, overwhelmingly. The American countertop trade runs on 3 cm slabs with an eased, laminated or built-up edge. 2 cm exists — mostly in commercial and multifamily work — but if you are quoting residential countertops in the US and you have not specified 3 cm, you have specified wrong.
Gangsaw slabs, not cutter slabs. American kitchens have large islands. Islands need full-block face. Cutter slabs are a niche product in the US and are not what a distributor's yard is stocked with.
Block-matched, sequence-numbered bundles. Not a request; an expectation. Sequence numbers written on the slab edge and repeated on the packing list. A bundle that arrives unnumbered is a bundle the fabricator cannot lay out for an island-and-peninsula job, and it will be remembered.
The Indian stones that carry the US market
| Stone | Verified origin | Position in the US |
|---|---|---|
| Absolute Black | Chamarajanagar (KA), Dharmapuri (TN); value tier Warangal/Khammam (TS) | The dark benchmark. Grade differs sharply by belt. |
| Black Galaxy | Chimakurthy, Ongole, Prakasam, AP | Feature stone. Known here as Star Galaxy. |
| Tan Brown | Karimnagar, Telangana | Volume neutral. Also English Brown, Chestnut Brown. |
| Kashmir White | Madurai / Melur, TN — not Kashmir | Long-running light seller. |
| Kashmir Gold | Madurai gold belt, TN — not Kashmir | Warm light, traditional kitchens. |
| Colonial White | Madurai, TN | Sold here as Bianco Romano / Buckingham White. |
| Colombo Juparana | Karur / Manapparai, TN | Banded exotic. Must be sequenced. |
| Steel Grey | Prakasam / Chimakurthy, AP | Commercial and multifamily volume. |
| Fantasy Brown | Sawar, Ajmer, Rajasthan | Label as quartzite — see below. |
| Alaska Gold / Alaska White | Deogarh, Rajasthan | Frequently mis-sold as Brazilian. They are not. |
| Rainforest Green / Brown / Gold | Bidasar, Churu, Rajasthan | Exotic marble. Serpentine, brittle, net-backed. |
| Makrana White Marble | Makrana, Nagaur, Rajasthan | IUGS heritage stone — see the Taj Mahal marble |
Two US-specific naming points
Fantasy Brown is a quartzite, not a marble. It is sold as "Fantasy Brown Marble" across most of the world. American fabricators, and more importantly their insurers and their customers, care about the distinction because it governs expected performance. Label it Fantasy Brown Quartzite.
Alaska Gold, Alaska White, Alaska Red, Alaska Pink and Patagonia Gold are Rajasthani, from the Deogarh belt. They are widely sold in the US as Brazilian. Brazil's "Patagonia" is a genuinely different stone — a quartzite. If a distributor is paying a Brazilian premium for Deogarh granite, they are paying twice for the same rock.
Also: do not use "White Glimmer" for Alaska White. It is another company's trademark. The correct description is Alaska White, Indian.
Test data US buyers expect
The American standard set for dimension stone, and what each covers:
| Standard | Covers |
|---|---|
| ASTM C615 | Granite dimension stone — the specification |
| ASTM C503 | Marble dimension stone |
| ASTM C568 | Limestone dimension stone |
| ASTM C616 | Quartz-based (sandstone / quartzite) dimension stone |
| ASTM C97 | Absorption and bulk specific gravity |
| ASTM C170 | Compressive strength |
| ASTM C99 | Modulus of rupture |
| ASTM C880 | Flexural strength |
| ASTM C241 / C1353 | Abrasion resistance |
You do not need every test on every slab. You need the supplier to have them for the quarry you are buying from, and to hand them over without a negotiation.
The Natural Stone Institute is the US industry body whose technical bulletins your fabricators and specifiers will reference. A supplier who has never heard of it is a supplier who has not sold into the US.
Port routing — this matters
Indian stone does not all ship from one place, and quoting the wrong port signals inexperience:
- Rajasthan and Gujarat material (marble, North granite, sandstone, Kota limestone) — Mundra / Kandla
- South Indian granite (Absolute Black, Black Galaxy, Tan Brown, Steel Grey, Kashmir White, Colonial White) — Chennai / Krishnapatnam
- Vizag-belt granite (Vizag Blue, Aspen White, Moon White) — Visakhapatnam
Transit to the US East Coast typically runs via Suez; to the West Coast, longer. Transhipment through Colombo, Jebel Ali or Singapore is common — keep the through bill of lading.
The duty position, stated carefully
The US position on Indian-origin goods has been unusually mobile since 2025, with additional measures layered on top of the standard HTSUS schedule. Any rate quoted in a blog post would be wrong by the time you read it.
What to do: ask your customs broker for the landed rate on your specific HTSUS classification, for your specific entry date, on every shipment, until the position settles.
What you can rely on is the classification structure — Chapter 25 for roughly trimmed blocks, Chapter 68 for worked stone, with 6801 for setts and kerbs and 6802 for worked monumental and building stone. See HS Codes for Natural Stone.
Container mechanics
Stone ships FCL in 20ft containers, effectively always. It reaches its weight limit long before its cubic capacity. At roughly 2,700 kg/m³, 3 cm granite weighs about 81 kg/m² before packing — so the container fills on the scale, not on the tape measure.
Details: Container Weight vs Volume and FCL vs LCL for Stone Shipments.
Buying terms
Most first-time US importers buy CIF and most experienced ones buy FOB, because a US distributor shipping volume has better ocean rates than an Indian exporter reselling freight. If you buy CIF, specify Institute Cargo Clauses (A) — the default under Incoterms 2020 is the restricted (C) cover, which is a poor fit for stone. Full comparison: Incoterms for Stone Importers.
Watch demurrage. A week of it on one container can exceed any duty advantage you were chasing.
What to ask an Indian supplier before the first order
- Which quarry, which district? Not "South India". A supplier with origin control names Chimakurthy, Karimnagar, Melur, Deogarh.
- Can I see block photos before sawing?
- Are bundles block-matched and sequence-numbered on the slab edge?
- Do you have ASTM data for this quarry?
- Is the material resined or net-backed? For Rainforest and other serpentine marbles, the answer is yes and it must be disclosed with a handling clause.
- What is your rejection rate on the line, and for what? A supplier who has never rejected a slab is not inspecting slabs.

What Gemarix does differently
We are a Rajasthan-based exporter with a verified origin map covering both North and South Indian material, and we publish it. Every quote carries state, district and — where our field research has confirmed it — village.
We correct our own records in public when field verification contradicts the trade's assumptions: Tan Brown is Karimnagar, not Salem. Lakha Red is Lakha village in Jaisalmer, not Sikar. Kandla Grey is Bijolia in Bhilwara, and is named after the export port, not the quarry.
And we keep foreign stone off the Indian list. Blue Pearl and Emerald Pearl are Norwegian larvikite. Baltic Brown is Finnish. Volga Blue is Ukrainian. Bianco Antico is Brazilian. They will never appear on an Indian-origin invoice from us.
Frequently Asked Questions
What thickness do US countertop fabricators buy?
3cm, overwhelmingly. The American countertop trade runs on 3cm slabs with an eased, laminated or built-up edge. 2cm exists mostly in commercial and multifamily work. If you are quoting residential countertops in the US and have not specified 3cm, you have specified wrong.
Is Kashmir White granite from Kashmir?
No. Kashmir White and Kashmir Gold are quarried around Madurai and Melur in Tamil Nadu, roughly two thousand kilometres from Kashmir. The names are long-standing trade conventions, not geography, and any supplier who lets you believe otherwise is a supplier to watch on other things too.
Is Alaska White granite Brazilian?
No. Alaska White, Alaska Gold, Alaska Red, Alaska Pink and Patagonia Gold are quarried in the Deogarh belt of Rajasthan. They are widely sold in the US as Brazilian material, so a distributor paying a Brazilian premium for them is paying twice for the same rock.
What is the US import duty on Indian granite?
Roughly 18 per cent under the US-India bilateral deal as at early 2026, down from a 50 per cent peak. The position has moved repeatedly, so verify the live HTS rate for your classification and entry date with your customs broker on every shipment.
Should Fantasy Brown be sold as marble or quartzite?
Quartzite. Fantasy Brown is quarried at Sawar in Ajmer, Rajasthan and is technically a quartzite, though it is sold as a marble across most of the world. US fabricators and their insurers care about the distinction because it governs expected performance.
