About Henan Mingshan Industry Charge Co., Ltd. - Silicon Supplier in China

Henan Mingshan Industry Charge Co., Ltd. is based in Henan province, China and currently lists five active products in its catalogue. The product list includes High Carbon Silicon, Ferro Silicon, Silicon Matel 553, Green and Black Silicon Carbide, and Calcium Silicon Alloy, all falling under the broader silicon and agriculture categories noted in the supplier profile. Each entry is presented without additional branding or client references, reflecting the factual data supplied. The supplier is classified with a "harbor" trust tier, indicating a verified status within the platform’s trust framework.

The five silicon‑related products cover both metallic silicon forms and silicon carbide variants. High Carbon Silicon and Silicon Matel 553 are silicon metals with elevated carbon content, while Ferro Silicon is an alloy used in steelmaking. Green and Black Silicon Carbide represent two common crystal colors used in abrasives and refractory applications, and Calcium Silicon Alloy combines calcium with silicon for specialized casting uses. No further company history, production capacity, or revenue figures are provided in the source data.

Product Range and Specialties of Henan Mingshan Industry Charge Co., Ltd.

The catalogue focuses on silicon‑based materials that serve metallurgical, electronic, and refractory markets. High Carbon Silicon typically offers a carbon content of 0.5‑1.5 % and silicon purity of 99.5 % or higher, while Silicon Matel 553 is commonly marketed as a high‑purity silicon metal (99.9 % Si) for photovoltaic and semiconductor uses. Ferro Silicon grades range from 15 % to 90 % silicon, with common forms supplied as lumps or granules for steel deoxidation. Green Silicon Carbide (SiC) is usually supplied in grain sizes of 0.5‑2 mm for polishing, whereas Black SiC is a denser, higher‑hardness variant used in grinding wheels. Calcium Silicon Alloy generally contains 10‑30 % calcium and is offered as ingots or castable pellets. Buyers often receive these materials in 20‑ft containers, bulk bags, or wooden crates depending on the product form.

Industry standards for these categories reference ASTM C1499 for silicon metal purity, ASTM C751 for silicon carbide grain size, and ISO 9001 quality‑management systems for consistent production. Typical specifications also include moisture content below 0.1 % for silicon metals and a bulk density of 3.2‑3.4 g/cm³ for silicon carbide powders. Such technical parameters help buyers compare offers across suppliers.

Trade and Export Information - Henan Mingshan Industry Charge Co., Ltd.

China is a leading exporter of silicon metals and silicon carbide, supplying downstream industries in East Asia, Europe, and North America. Major importers include South Korea and Japan for semiconductor‑grade silicon, the United States and Germany for ferro‑silicon used in steel plants, and Brazil for refractory silicon carbide. Export shipments are usually arranged under FOB or CIF terms, with containers loaded on major Chinese ports such as Shanghai, Tianjin, and Qingdao. Buyers commonly request third‑party inspection reports from SGS, BV, or Intertek, along with certificates of analysis that confirm purity, carbon content, and particle‑size distribution.

Typical certifications required for these materials are ISO 9001 for quality management, ISO 14001 for environmental compliance, and material safety data sheets (MSDS) for handling and transport. Chinese customs may also require a declaration of the HS chapter (e.g., Chapter 28 for silicon and Chapter 29 for ferro‑silicon) and a commercial invoice detailing weight, net weight, and packaging type. Bulk shipments are frequently packed in 1‑ton polyethylene bags placed within a 20‑ft container, while smaller orders may be shipped in wooden crates with moisture‑barrier liners to preserve material integrity.

Sourcing from Henan Mingshan Industry Charge Co., Ltd. - Buyer Guidance

When sourcing silicon metals or silicon carbide from this supplier, request an up‑to‑date assay certificate that specifies silicon purity, carbon content, and any residual metal impurities. A material safety data sheet should be obtained for each product to verify handling requirements, especially for high‑carbon silicon and calcium silicon alloy, which can be reactive under certain conditions. Buyers are advised to confirm the grain‑size distribution for silicon carbide (e.g., 0.5‑2 mm for green SiC) and to ask for a recent third‑party inspection report to validate compliance with ASTM or ISO standards.

Typical minimum order quantities for bulk silicon metal range from 1 ton to 5 tons, while silicon carbide may be ordered in 500 kg increments depending on the grade. Lead times in China for these products are generally 30‑45 days after receipt of a pro‑forma invoice, with possible extensions during peak export seasons. Verify packaging details - whether the material will be shipped in bulk bags, sealed drums, or wooden crates - and confirm the Incoterm (FOB, CIF, or DDP) before finalizing the purchase agreement.

What purity levels are available for High Carbon Silicon?

High Carbon Silicon is commonly offered with silicon purity between 99.5 % and 99.8 %, and a carbon content of 0.5‑1.5 %. Buyers should request a certificate of analysis that confirms these figures for each shipment.

How is Ferro Silicon graded and what are typical specifications?

Ferro Silicon grades are defined by their silicon content, usually ranging from 15 % to 90 % Si. Standard specifications include low phosphorus (<0.03 %) and low aluminum (<0.05 %) levels, and buyers should ask for an assay report and an SGS inspection certificate.

What are the differences between Green and Black Silicon Carbide?

Green Silicon Carbide is a translucent form with grain sizes suited for polishing applications, while Black Silicon Carbide is denser and harder, used for grinding wheels. Both grades are typically supplied in 0.5‑2 mm granules and should be accompanied by a particle‑size distribution chart.

Is a Material Safety Data Sheet (MSDS) provided for Calcium Silicon Alloy?

Yes, an MSDS is standard for calcium‑silicon alloys due to their reactivity with moisture. Request the latest MSDS to understand storage, handling, and transport precautions before placing an order.

What are the common packaging options for these silicon products?

Bulk silicon metals are usually packed in 1‑ton polyethylene bags inside a 20‑ft container, while silicon carbide may be shipped in sealed wooden crates with moisture‑barrier liners. Confirm the packaging method to ensure product integrity during transit.

Which certifications should I verify before purchasing?

Buyers should verify ISO 9001 quality‑management certification, ISO 14001 environmental compliance, and obtain third‑party inspection reports (e.g., SGS, BV). Additionally, request a certificate of analysis and MSDS for each product.

What are typical lead times and minimum order quantities?

Lead times from China are generally 30‑45 days after order confirmation. Minimum order quantities are around 1 ton for silicon metals and 500 kg for silicon carbide, though exact figures depend on the specific grade.

Which regions most frequently import these silicon products?

Key import regions include East Asia (South Korea, Japan, Taiwan) for semiconductor‑grade silicon, North America and Europe for ferro‑silicon used in steelmaking, and Southeast Asia for refractory silicon carbide applications.
