About Yagna Associate - Sandstones & Sands Supplier in India

Yagna Associate is based in India and currently lists seven distinct mineral products. The catalogue covers four main categories: sandstones and sands, silica sand, limestone and clay. Within the sand segment the supplier offers glass grade silica sand, fracking sand, foundry sand, recreational sand and water filtration sand. The limestone offering is listed simply as Lime Stone, while the clay product is China Clay (Kaolinite). The glass grade silica sand is specified with a material description of silica sand SiO2 99%+ and carries HS code 2505.10. The China Clay entry includes HS code 2507.00 and the chemical formula Al2Si2O5(OH)4.

The HS code 2505.10 places the glass grade silica sand in the chapter for mineral fuels, mineral oils and products of their distillation, a common classification for industrial sand used in glass manufacturing. The other sand types share the same HS chapter but are not assigned specific codes in the provided data. Lime Stone falls under the HS chapter 25 for mineral products, typically HS 2515 for natural limestone. Kaolinite is classified under HS 2507 for kaolin and other ceramic raw materials. All seven products are described without additional quantitative specifications such as grain size, moisture content or bulk density, which are standard parameters buyers request. The supplier’s active product count and category spread indicate a focus on bulk mineral commodities for industrial processing.

Product Range and Specialties of Yagna Associate

The catalogue lists five sand products - glass grade silica sand, fracking sand, foundry sand, recreational sand and water filtration sand - each belonging to the broader silica sand market. In the industry glass grade silica sand is typically required to meet a minimum SiO2 purity of 99.5%, grain size distribution between 150 µm and 300 µm, and moisture content below 0.5% as per ASTM C144. Fracking sand, often marketed as proppant, generally conforms to API specifications for crush resistance (minimum 7,000 psi) and roundness above 0.85. Foundry sand is usually graded for silica content above 95% and must pass the AFS (American Foundry Society) sand testing for permeability and grain shape. Recreational sand for playgrounds and sports fields commonly follows the ASTM F710 standard, limiting fines to less than 0.5% and ensuring a clean, dust‑free product. Water filtration sand is specified for a uniform grain size (0.6 - 1.2 mm) and a high porosity, often verified by ISO 9033. The limestone entry is presented without grade detail, but Indian limestone exporters typically supply material with calcium carbonate content of 85 - 95% and low magnesium oxide, suitable for construction aggregates or cement raw meal. Kaolinite (China Clay) is usually offered in grades ranging from industrial grade (purity 45 - 55% Al2O3) to high‑purity ceramic grade (purity > 60% Al2O3) with particle sizes between 2 µm and 20 µm, complying with ISO 10545‑3 for ceramics. Standard documentation for these minerals includes SGS or Bureau Veritas analysis certificates, bulk density reports, and safety data sheets.

Trade and Export Information - Yagna Associate

India is a major exporter of industrial sand, limestone and kaolin, with shipments typically destined for glass manufacturers in the Middle East, oil‑field service companies in North America, foundries in Europe, and water‑treatment plants in Southeast Asia. The HS code 2505.10 for glass grade silica sand aligns with customs data showing annual Indian exports of several hundred thousand metric tonnes to the United Arab Emirates, Saudi Arabia and Qatar. Limestone under HS 2515 is commonly shipped in bulk bags or open‑top containers to cement plants in Africa and the Indian sub‑continent. Kaolin (HS 2507) is frequently exported to the ceramics and paper industries in China, Brazil and the United States, often under CIF or FOB terms. Buyers of these mineral commodities usually require ISO 9001 quality management certification, ISO 14001 environmental compliance, and third‑party laboratory reports confirming chemical composition and physical properties. Typical packaging includes 20‑ft or 40‑ft containers with bulk bags (25 kg each) or flexible bulk liners for larger volumes, and the goods are classified under HS chapter 25 for customs clearance. Regulatory inspections may involve customs sampling, SGS verification, and adherence to REACH restrictions for silica dust exposure. Incoterms most frequently used by Indian exporters are FOB Mumbai or CIF Dubai, depending on the destination market.

Sourcing from Yagna Associate - Buyer Guidance

When sourcing silica sand from Yagna Associate, request a recent SGS test report showing SiO2 purity, grain size distribution, moisture content and bulk density. For fracking and foundry sand, ask for compliance certificates to API 13A and AFS standards respectively, together with crush resistance and permeability data. Water filtration sand should be accompanied by a porosity test and a declaration that the product meets ASTM F710 or ISO 9033 limits for fines. Limestone purchases should be verified against a calcium carbonate assay and a low‑magnesium specification, with a bulk sample inspected for particle size suitable for the intended process. For China Clay, obtain a mineralogical analysis indicating Al2O3, SiO2 and impurity levels, and confirm the grade (industrial or ceramic) through an ISO 10545‑3 report. Before confirming orders, validate the supplier’s ISO 9001 certificate, request a copy of the latest customs export clearance, and clarify packaging size, MOQ (commonly 20 tonnes) and lead time, which in India averages 30‑45 days.

What HS codes are associated with Yagna Associate’s silica sand products?

The glass grade silica sand is listed under HS code 2505.10. Other sand products are classified within HS chapter 25 for mineral sands, but no separate HS codes were provided for those items in the catalogue.

Which standards should buyers check for glass grade silica sand?

Buyers typically verify compliance with ASTM C144, which requires a SiO2 purity of at least 99.5%, grain size between 150 µm and 300 µm, and moisture below 0.5%. An up‑to‑date SGS or equivalent laboratory analysis should be requested to confirm these parameters.

What documentation is commonly required for fracking sand?

Fracking sand is usually required to meet API 13A specifications for proppant, including a minimum crush resistance of 7,000 psi and a roundness index above 0.85. Buyers should also obtain a material safety data sheet and bulk density report before purchase.

How is limestone usually specified for export?

Limestone exports are commonly specified by calcium carbonate content of 85‑95% and low magnesium oxide levels, with particle size suited to cement or construction use. A laboratory assay and an ISO 9001 quality certificate are standard documents requested by buyers.

What grade information is typical for China Clay (Kaolinite)?

China Clay is typically offered in industrial grade (45‑55% Al2O3) or high‑purity ceramic grade (>60% Al2O3) with particle sizes ranging from 2 µm to 20 µm. Buyers should ask for an ISO 10545‑3 analysis report and a purity certification to confirm the grade.

Which packaging formats are used for bulk mineral shipments from India?

Bulk mineral shipments from India are usually packed in 25 kg polypropylene bulk bags, which are then loaded into 20‑ft or 40‑ft containers for sea freight. For very large quantities, flexible bulk liners or open‑top containers may be used, and the exact packaging terms are detailed in the pro‑forma invoice.

What incoterms are typically applied to shipments of these minerals?

Exporters often quote FOB from major Indian ports such as Mumbai or Chennai, allowing the buyer to arrange main carriage. For deliveries to regional hubs, CIF terms to ports like Dubai are also frequently applied.
