About Guru Corporation - Industrial Chemicals Supplier in India

India hosts Guru Corporation, an imported‑tier supplier that currently lists 15 active products. The catalogue spans categories such as Other Ores & Minerals, Industrial Chemicals, Silica Sand, Cement, Bricks, Slag and Silica Gel. Specific items include Nozzle Filling Compound, Micro Silica, Rice Husk Ash, HEAT (Radex) Insulation Compound, Casting Powder (HS 3824.99), Cast Iron Powder (HS 7205.29), Vermiculite (HS 6806.20), Synthetic Slag (HS 2619.00), Tundish Covering Compound (HS 3816.00), Silica Fume (HS 2811.22), Radex Powder (HS 3816.00), G‑Fine Ultrafine Cement Additive (HS 3824.99), Insulation Refractories Powder RADEX (HS 6902.90), Slag Conditioner Briquetes (HS 2619.00) and G‑Chem Silica Fume. Each product is linked to a material description that ranges from silicate‑based flux blends to calcium aluminate‑silicate compounds and high‑alumina refractory powders. The listed HS‑code families cover chapters 26, 28, 38, 68, 69 and 72, reflecting the mineral and chemical nature of the range.

The product mix focuses on high‑temperature and cement‑related materials. Silica‑based additives such as Micro Silica, Silica Fume and G‑Fine Ultrafine Cement Additive serve as pozzolanic fillers, while flux‑type powders like Casting Powder and Synthetic Slag are intended for metallurgical processes. Refractory compounds (Radex Powder, Insulation Refractories Powder) and vermiculite address thermal insulation needs. The presence of cast iron powder (Fe 92‑96 %) and slag conditioner briquettes indicates a focus on metal‑foundry and steel‑making applications. All items are presented without any claimed certifications or performance guarantees beyond the material statements supplied.

Product Range and Specialties of Guru Corporation

Guru Corporation’s catalogue groups its 15 items into three functional clusters: pozzolanic and cementitious additives, metallurgical fluxes and refractories, and mineral insulation products. The pozzolanic line includes Silica Fume, G‑Fine Ultrafine Cement Additive and G‑Chem Silica Fume, which typically meet industry standards of ≥ 95 % SiO₂ purity, particle sizes between 0.1‑0.5 µm and a specific surface area of 20‑25 m²/g. The metallurgical cluster comprises Casting Powder (silicate‑based flux), Synthetic Slag (calcium aluminate‑silicate flux) and Slag Conditioner Briquettes (CaO‑Al₂O₃‑fluorspar blend), products that in the sector are graded by melt‑temperature range (1 200‑1 500 °C) and basicity index. Refractory offerings such as Radex Powder, Insulation Refractories Powder RADEX and Tundish Covering Compound are aluminosilicate‑based, generally conforming to ASTM C618 or EN 13670 specifications for high‑alumina refractories. Vermiculite, listed under HS 6806.20, is a hydrated magnesium‑aluminum silicate mineral with bulk density 70‑120 kg/m³ and thermal conductivity 0.06‑0.08 W/m·K, matching typical insulation grades. Cast Iron Powder (Fe 92‑96 %) aligns with powder‑metallurgy standards that require particle size distribution D10‑D90 of 10‑150 µm and low oxygen content.

Trade and Export Information - Guru Corporation

India is a major exporter of industrial minerals and specialty chemicals, and products such as silica fume, synthetic slag and refractory powders are regularly shipped to construction, steel‑making and foundry hubs in the Middle East, Southeast Asia, Europe and North America. The HS‑code families present in Guru Corporation’s list (e.g., 38 for chemical products, 72 for iron powders, 68 for vermiculite, 26 for slags, 28 for silica products and 69 for refractory materials) are subject to standard customs documentation, including a commercial invoice, packing list and, where required, a certificate of origin. Buyers typically request ISO 9001 quality‑management certification, as well as product‑specific standards such as ASTM C618 for pozzolanic additives, ASTM C155 for refractory powders, and EN 197‑1 for cementitious materials. Shipping is commonly arranged in 20 ft or 40 ft containers, bulk bags (1 ton) or steel drums, with moisture‑proof liners for cement additives and refractory powders; FOB and CIF terms are standard in Indian export contracts.

Sourcing from Guru Corporation - Buyer Guidance

When sourcing from Guru Corporation, buyers should obtain a Material Safety Data Sheet for each chemical‑based product and request analytical test reports that confirm purity (e.g., SiO₂ ≥ 95 % for silica fume), iron content (Fe 92‑96 % for cast iron powder) and particle‑size distribution. For refractory and insulation powders, verification of high‑alumina content (≥ 45 % Al₂O₃) and refractory grade (e.g., ASTM C155) is advisable, together with bulk density and moisture‑content measurements. Importers targeting the EU market should ask for REACH compliance documentation, while those supplying the US should request EPA‑TSCA or ASTM certifications. Confirm packaging integrity (sealed bulk bags or drums) and ensure that the supplier can provide certificates of origin and, if available, ISO 9001 audit reports before finalizing the order.

What product categories does Guru Corporation offer?

Guru Corporation lists 15 items across Industrial Chemicals, Other Ores & Minerals, Silica Sand, Cement, Bricks, Slag and Silica Gel. The range includes flux powders, cementitious additives, refractory compounds, vermiculite and cast iron powder.

Which HS code applies to the Casting Powder?

Casting Powder is recorded under HS code 3824.99, which covers other chemical products not elsewhere specified. This code is used for silicate‑based metallurgical flux blends.

What are the typical specifications for the silica fume supplied?

Silica fume products such as Silica Fume and G‑Chem Silica Fume are silicon dioxide with purity typically ≥ 95 %, particle size 0.1‑0.5 µm and specific surface area around 20‑25 m²/g. They are classified under HS 2811.22.

How is vermiculite classified and what are its common uses?

Vermiculite is classified under HS code 6806.20 as a hydrated magnesium‑aluminum silicate mineral. It is widely used for thermal insulation, fire‑proofing and as a lightweight aggregate in construction.

What documentation should a buyer request for cast iron powder?

Buyers should request a Material Safety Data Sheet, an assay report confirming Fe content of 92‑96 wt %, particle‑size distribution data, and any applicable ISO or ASTM test certificates.

Which packaging formats are typical for the G‑Fine Ultrafine Cement Additive?

The ultrafine cement additive is usually shipped in 20 ft or 40 ft containers, packed in 1‑ton bulk bags or in sealed steel drums to protect against moisture. Bulk bags are often lined with polyethylene for added barrier protection.

What certifications are commonly required for refractory powders exported from India?

Importers generally require ISO 9001 quality‑management certification and product‑specific standards such as ASTM C618 for pozzolanic materials or EN 13670 for refractory products. Buyers should ask the supplier to provide copies of these certificates before purchase.
