About Wude Group Co. Limited - Silicon Supplier in China

Wude Group Co. Limited is based in China and currently lists 24 active products. The supplier’s catalogue spans silicon alloys, ferroalloys, industrial chemicals and metal products. Products such as Ferro Silicon, Ferro Silicon Powder and Ferro Silicon Aluminum are recorded without HS codes, while the Si‑Zr Inoculant is listed under HS code 7202.99 as a silicon‑zirconium alloy. Other items with HS codes include Magnesium Ingot (8104.11), Electrolytic Manganese (8111.00), Calcium Metal Granules (2805.12), Cored Wire (7204.29), Manganese Ore (2602.00), Calcium Chloride Prill (2827.31) and Silicon Carbide (2849.20). The remaining entries such as Magnesium Chloride variants, Rare Ferro Silicon Magnesium and various inoculants are presented without HS classification. The product list reflects typical raw material grades used in metallurgy, alloying and chemical processing.

Ferro Silicon and its powder form are commonly supplied with silicon content between 70‑85 % for steel deoxidation. Silicon‑Zirconium inoculants typically contain 60‑75 % silicon and 5‑15 % zirconium and are used in cast‑iron treatment. Magnesium ingots at 99.9 % purity serve as feedstock for die‑casting and alloy production. Electrolytic manganese of 99.7 % purity is a standard grade for stainless‑steel and battery alloys. Calcium metal granules of 98.5‑99.5 % purity are employed as reducing agents and alloying additives. Cored wire combines a steel sheath with a powdered ferroalloy core for continuous‑casting applications. Manganese ore with 44‑48 % Mn is a primary source for ferro‑manganese production. Calcium chloride prills with 74‑94 % purity are used in de‑icing and dust‑control. Silicon carbide listed as black/green grade is a refractory and abrasive material.

Product Range and Specialties of Wude Group Co. Limited

The catalogue includes ferro silicon variants (plain, powder, aluminum‑bearing and Ba inoculant), silicon‑zirconium alloy (Si‑Zr Inoculant, HS 7202.99), magnesium ingot (99.9 % purity, HS 8104.11), electrolytic manganese (99.7 % purity, HS 8111.00), calcium metal granules (98.5‑99.5 % purity, HS 2805.12), cored wire with a steel sheath and ferroalloy core (HS 7204.29), manganese ore (44‑48 % Mn, HS 2602.00), calcium chloride prill (74‑94 % purity, HS 2827.31) and silicon carbide (black/green grade, HS 2849.20). Industry practice classifies ferro silicon into FeSi75, FeSi75P and FeSi85 grades according to silicon content and phosphorus addition, typically supplied in 25 kg bags or 1 ton bulk bags. Silicon‑zirconium inoculants are graded by Si/Zr ratio and are often certified to ASTM B928 for composition. Magnesium ingots are shipped in 10 kg or 25 kg ingot blocks and conform to ASTM B193 standards. Electrolytic manganese usually meets ISO 9001 quality management and is shipped in 20 ft containers with moisture <0.5 %. Calcium metal granules are packaged in sealed drums to prevent oxidation, with purity verified by ICP‑AES. Silicon carbide grades are identified by grain size (e.g., 10 µm, 20 µm) and follow ASTM B511 specifications. Typical packaging for bulk chemicals such as calcium chloride prills is 25 kg polypropylene bags, and for magnesium chloride variants 20 kg bags.

Trade and Export Information - Wude Group Co. Limited

China is a major exporter of ferroalloys, silicon‑based alloys and industrial chemicals, with primary destinations in Southeast Asia, the European Union and North America. HS chapter 72 items such as Si‑Zr Inoculant (7202.99) and Cored Wire (7204.29) are subject to customs duties that vary by destination but often qualify for preferential rates under existing trade agreements. HS chapter 81 products like Magnesium Ingot (8104.11) and Electrolytic Manganese (8111.00) typically require material safety data sheets (MSDS) and test certificates confirming purity and moisture content. Buyers of silicon carbide (HS 2849.20) frequently request compliance with REACH and CE marking for downstream applications in abrasives and refractories. Standard export logistics from Chinese ports involve FOB Shanghai or Ningbo, with container loading in 20 ft or 40 ft units; bulk chemicals may also be shipped in bulk tankers under CIF terms. Importing countries often demand ISO 9001 or ISO 14001 certification of the manufacturing facility, as well as third‑party assay reports for metal grades.

Sourcing from Wude Group Co. Limited - Buyer Guidance

When sourcing from Wude Group, request an assay certificate that specifies elemental composition (e.g., Si % for ferro silicon, Mg % for magnesium ingot) and impurity limits such as Al, P or Fe. Verify that the supplier can provide MSDS, REACH compliance statements for chemical products and, where applicable, ISO 9001 quality management certificates. For inoculants and specialty alloys, ask for a test report that includes particle size distribution and trace‑element analysis. Confirm packaging details - 25 kg bags for ferro silicon, sealed drums for calcium metal granules, and bulk containers for manganese ore - to ensure compatibility with your handling facilities. Typical lead times for bulk metal grades from Chinese manufacturers range from 30 to 45 days after order confirmation, with optional pre‑shipment sampling if required.

What HS code is assigned to the Si‑Zr Inoculant listed by Wude Group?

The Si‑Zr Inoculant is listed under HS code 7202.99, which covers other alloys of iron and steel with silicon and zirconium content.

What purity level is standard for the Magnesium Ingot offered?

The catalogue states a purity of 99.9 % magnesium metal (Mg 99.9 %). Buyers normally request an ICP‑AES assay report confirming this level.

Which documentation should a buyer request for the Electrolytic Manganese?

A buyer should ask for an assay certificate showing 99.7 % manganese purity, an MSDS, and any applicable REACH registration documents.

What are the typical packaging formats for Calcium Chloride Prill?

Calcium Chloride Prill is commonly packed in 25 kg polypropylene bags, which aligns with the supplier’s listed material specifications.

Is there a minimum order quantity for Silicon Carbide?

The catalogue does not specify an MOQ, but industry practice for bulk silicon carbide (black/green grade) is a minimum of one 20 ft container (approximately 12‑15 tons).

What certifications are commonly required for the ferro silicon products?

Buyers usually require ISO 9001 quality management certification and a third‑party assay report meeting ASTM B931 specifications for ferro silicon grades.

How is the Cored Wire typically shipped?

Cored Wire (HS 7204.29) is generally shipped in steel‑coated spools or bulk in 20 ft containers, with the outer steel sheath protecting the powdered ferroalloy core.

Can samples be requested before a full order?

Yes, suppliers of metal alloys and chemicals typically provide small‑scale samples (e.g., 1 kg for ferro silicon or a few bags of chemicals) along with the relevant test reports for buyer evaluation.
