Product Range and Specialties of Silver Stone Industries

The product catalogue comprises six mineral powders. Calcium Carbonate is offered without a specified grade, but industry standards often reference ICC 150 (high purity, 95 % CaCO₃) and ICC 200 (lower purity, 85‑90 % CaCO₃). Dolomite products are typically graded by calcium to magnesium ratios, with standard commercial dolomite containing about 38 % CaCO₃ and 20 % MgO. Low Silica Dolomite is a variant where silica content is kept below 2 % to meet ceramic glaze specifications. Talc and Dolo Talc are fine‑particle silicates; commercial talc grades range from 99 % purity with a moisture content under 0.5 % to finer grades for cosmetics that meet ISO 12784. Marble Powder is a calcite‑rich powder with typical particle size distribution of 10‑150 µm, used where a smooth finish is required.

Trade and Export Information - Silver Stone Industries

India is a major exporter of industrial minerals, and shipments of calcium carbonate, dolomite and talc are routinely directed to Southeast Asia, the Middle East, Europe and North America. HS code 2520 covers calcium carbonate, 2515 covers dolomite and 2504 covers talc; these codes are used by customs authorities to classify the goods for duty assessment. Buyers usually request compliance with ISO 9001 quality management systems and third‑party lab reports such as SGS or Bureau Veritas. Typical export logistics involve containerised loads (20 ft or 40 ft) with the product bagged in polypropylene or paper bags of 20‑25 kg. Incoterms most often applied are FOB Udaipur or CIF destination port, depending on the buyer’s preference. Indian mineral exporters must provide a Certificate of Origin and, where required, a Phytosanitary Certificate for dolomite used in agricultural applications.

Sourcing from Silver Stone Industries - Buyer Guidance

When sourcing from Silver Stone Industries, buyers should request a recent Material Safety Data Sheet (MSDS) and a laboratory analysis report that includes purity, moisture, particle size distribution and heavy‑metal limits. For calcium carbonate and dolomite, verify the CaCO₃ and MgO percentages against the intended application specifications. Talc grades should be checked for asbestos‑free certification and a loss on ignition (LOI) value below 0.2 %. It is advisable to obtain a sample batch before confirming a full order, and to confirm the packaging material (e.g., multi‑layer bags) meets the shipping route’s humidity conditions. Clarify the minimum order quantity, typical lead time of 30‑45 days after order confirmation, and the preferred Incoterm to align with your logistics plan.
