About Sonnet Stone Pvt. Ltd. - Stone Products Supplier in India

Sonnet Stone Pvt. Ltd. operates from India and currently lists five active stone products in its catalogue. The product names are Kandla-grey, Black slates, Agra-Red (N & P), Green-Forest-1, and Bala-Flower. These items are grouped under the supplier’s top categories of Stone Products, Slates, Sandstones & Sands, Marble Slabs and Granite Slabs. The company is classified as an imported supplier with a harbor trust tier in the trade platform. All five products are natural stone varieties that are commonly used in construction, interior design and landscaping projects.

In international trade, the listed stone items fall under HS chapter 68, where polished marble and granite slabs are recorded under HS 6802 and rough or dressed stone under HS 6803. Kandla-grey and Black slates are typical of polished or honed finishes, while Agra-Red (N & P) represents red sandstone blocks. Green-Forest-1 and Bala-Flower correspond to coloured slate and patterned marble respectively, each supplied in standard slab dimensions such as 2 m × 1 m. The catalogue’s focus on five distinct colour and texture options reflects a targeted product range rather than a broad inventory. Buyers can expect the listed items to meet the dimensional tolerances and surface quality standards commonly required for architectural stone.

Product Range and Specialties of Sonnet Stone Pvt. Ltd.

The catalogue offers Kandla-grey, a medium‑grey granite slab usually supplied in thicknesses of 20 mm to 30 mm and suitable for flooring, countertops and external cladding. Black slates are fine‑grained metamorphic rocks offered in 10 mm to 15 mm thickness, frequently used for roofing tiles, paving and wall cladding. Agra-Red (N & P) denotes red sandstone blocks that are cut to standard sizes of 1 m × 0.5 m or larger, with typical compressive strength around 70 MPa and water absorption below 2 %. Green‑Forest‑1 is a green‑tinged slate variant, often marketed in honed or brushed finishes for decorative panels. Bala‑Flower is a patterned marble slab characterized by veined white and pastel colours, commonly graded by ICUMSA whiteness and supplied in 2 m × 1 m panels. Industry practice grades granite by colour uniformity and surface finish, marble by veining pattern and polish level, and slates by thickness and flexural strength; buyers usually request a material certificate and a sample to verify these specifications.

Trade and Export Information - Sonnet Stone Pvt. Ltd.

India is a major exporter of natural stone, with the majority of shipments destined for the Middle East, Europe and North America, where the construction and interior‑fitout sectors drive demand. Stone products classified under HS 6802 and 6803 are typically loaded in 20‑ft or 40‑ft containers on wooden pallets or steel frames, and customs inspections often focus on documentation such as a commercial invoice, packing list and a certificate of origin. Common buyer requirements include ISO 9001 quality management certification, compliance with ASTM C615 for natural stone, and, for certain markets, CE marking or SGS inspection reports. Export logistics from Indian ports usually follow Incoterms FOB or CIF, with freight forwarders handling container loading and customs clearance. Seasonal demand peaks in the northern hemisphere’s spring and summer construction cycles, influencing lead times and container availability.

Sourcing from Sonnet Stone Pvt. Ltd. - Buyer Guidance

When sourcing stone from Sonnet Stone Pvt. Ltd., buyers should request product samples cut to the intended slab size to assess colour consistency, surface finish and dimensional accuracy. Verification documents normally include an ISO 9001 certificate, a mill test report detailing compressive strength, water absorption and density, and a certificate of origin for customs purposes. Buyers are advised to confirm the HS code (6802 for polished slabs or 6803 for rough stone) that matches the specific product, and to clarify the packaging method - typically wooden crates with moisture‑resistant lining - to avoid damage during sea transit. Minimum order quantities often start at one 20‑ft container (approximately 12  -  15 tonnes of stone), with lead times ranging from 30 to 45 days after sample approval.
