About Anyang Hengsheng Metallurgical Refractories Co., Ltd. - Silicon Supplier in China

China‑based Anyang Hengsheng Metallurgical Refractories Co., Ltd. lists twelve active products across the Silicon, Agriculture and Chemicals & Allied Products categories. The catalogue includes Silicon Metal Powder, various grades of ferro‑silicon (Fesi, Fesi 75, Ferro Silicon, Ferro Silicon Barium, Rare Earth Ferro Silicon, Calcium Silicon Manganese, Ferro Chrome Low Carbon, Ferro Silicon Zirconium Inoculant) and related inoculants such as Calcium Granules. Each entry is recorded without a specific HS‑code in the supplied data, but the product families map to standard HS chapters for silicon and ferro‑alloys. The supplier’s trust tier is listed as “harbor,” indicating a moderate level of verification within the platform. The product set reflects a focus on metallurgical additives used in steelmaking and alloy production.

The product portfolio covers both pure silicon forms and alloyed ferro‑silicon variants that are typical inputs for de‑oxidation, de‑carburisation and alloying in the steel industry. Silicon Metal Powder generally conforms to purity grades of 99.5 % Si or higher, while ferro‑silicon grades such as FeSi 75 contain roughly 75 % silicon and 25 % iron. Inoculants such as Calcium Granules and Ferro Silicon Zirconium Inoculant are supplied for alloy refinement and cast iron treatment. Although HS codes are not supplied, these items usually fall under HS 2602 (silicon) and HS 7202‑7204 (ferro‑alloys). The range suggests capability to serve downstream metallurgical processes that require precise silicon content and controlled impurity levels.

Product Range and Specialties of Anyang Hengsheng Metallurgical Refractories Co., Ltd.

The catalogue presents a core set of ferro‑silicon products ranging from standard FeSi to specialised blends such as FeSi 75 Mg (Ferro Silicon Magnesium Nodulizer) and Rare Earth Ferro Silicon. In the global market, ferro‑silicon is typically graded by silicon content (e.g., FeSi 75, FeSi 65) and may include magnesium or calcium modifiers to improve fluidity and reduce slag formation. Silicon Metal Powder is commonly offered in 99.5 % or 99.9 % purity, with particle sizes from 10 µm to 200 µm depending on end‑use. Calcium‑based inoculants are measured by calcium oxide (CaO) content and are used in cast iron to promote graphite formation. Buyers usually request material safety data sheets (MSDS), purity certificates and, where relevant, compliance with ISO 9001 quality management systems.

Trade and Export Information - Anyang Hengsheng Metallurgical Refractories Co., Ltd.

China is among the world’s largest exporters of ferro‑alloys, supplying steel producers in Southeast Asia, the Middle East, Europe and the Americas. HS chapter 72 (iron and steel) and chapter 26 (non‑metallic minerals) cover the majority of the listed items, with typical HS codes 7202 90 for ferro‑silicon and 2602 90 for silicon metal powder. Importing countries often require certificates of origin, test reports confirming silicon content, and compliance with standards such as EN 10204 3.1 for test‑certificate material. Common certifications requested by buyers include ISO 9001 for quality management and, for certain applications, ISO 14001 environmental management. Export logistics from China usually involve 20‑ft or 40‑ft containers, with bulk bags of 1 ton or 25 kg bags for finer powders, and the Incoterms CIF or FOB are frequently used.

Regulatory expectations for ferro‑alloys include adherence to the EU REACH regulation for hazardous substances and the US ASTM A 470 standard for ferro‑silicon composition. Packaging must protect against moisture, as silicon powders are hygroscopic; moisture content below 0.5 % is a typical specification. Customs authorities often inspect for correct HS classification and verify that the declared silicon percentage matches laboratory analysis. Buyers in the automotive and construction steel sectors prioritize low impurity levels (e.g., aluminium <0.05 %, phosphorus <0.02 %) and may request additional testing such as X‑ray fluorescence (XRF) or inductively coupled plasma (ICP) analysis.

Sourcing from Anyang Hengsheng Metallurgical Refractories Co., Ltd. - Buyer Guidance

When sourcing from Anyang Hengsheng Metallurgical Refractories Co., Ltd., buyers should request a recent assay report that details silicon, iron, magnesium and any added alloying elements for each ferro‑silicon grade. Samples should be evaluated for particle size distribution (for powders) and bulk density (for granules) to confirm suitability for the intended melt process. Documentation to verify should include a material safety data sheet, a certificate of origin and, where applicable, evidence of ISO 9001 certification from the supplier’s quality system. Verifying that the supplier can provide batch‑by‑batch test certificates helps mitigate risk of composition deviation, which can affect steel chemistry and downstream product quality.

What purity levels are typical for the Silicon Metal Powder offered by this supplier?

Silicon Metal Powder from Chinese exporters is commonly supplied at 99.5 % Si or higher, with impurity limits such as Al < 0.03 % and Fe < 0.05 %.

Which HS codes apply to the ferro‑silicon products listed?

Ferro‑silicon alloys generally fall under HS 7202 90, while silicon‑based powders are classified under HS 2602 90.

What documentation should a buyer request before placing an order?

Buyers should ask for an assay certificate, a material safety data sheet, a certificate of origin and, if available, the supplier’s ISO 9001 quality management certificate.

What are the typical packaging formats for these products?

Bulk ferro‑silicon is usually packed in 1‑ton steel drums or 25 kg polypropylene bags; silicon powders are often supplied in 20 kg or 25 kg moisture‑resistant bags.

Which regions import ferro‑silicon and silicon powders most frequently?

Major importers include steel‑producing regions in Southeast Asia, the Middle East, the European Union and North America.

What are common minimum order quantities (MOQs) for ferro‑silicon grades?

MOQs typically range from 5 tons for standard FeSi grades to 1 ton for specialised inoculants, depending on packaging and shipping arrangements.
