About Shandong Huamin Steel Ball Joint-stock CO,LTD. - Steel Balls Supplier in China

Shandong Huamin Steel Ball Joint-stock CO,LTD. is located in Shandong province, China and lists ten active product entries in its catalogue. The catalogue covers forged steel grinding balls, alloy‑steel balls and related grinding rods, each identified under HS codes 7325.90, 7325.91, 7326.11 and 7213.91. Product descriptions reference diameters ranging from 20 mm up to 150 mm and materials such as high‑carbon steel, alloy steel, Cr‑Mo (B2/B3) and high‑chrome cast iron. The supplier notes export destinations that include the United States, Canada, Chile, South Africa, Italy, Greece, Korea and Japan, indicating a presence in more than twenty countries. ISO 9001:2000 and ISO 14001:2004 certifications are listed among the company’s documented quality and environmental systems.

The listed items include a 5.5" (146 mm) forged steel ball for copper mines, 100 - 150 mm forged balls for gold and copper mining, 25 mm rolling forged balls for ball mills, and a series of 40 - 65 mm and 1 - 3 inches balls classified as B2/B3 grade. Additional entries describe high‑hardness steel grinding rods (HS 7213.91) and generic alloy‑steel grinding balls. All entries fall within the broader grinding media category used in mineral processing, cement grinding and power‑generation applications. The product set therefore spans both high‑hardness steel media for ore reduction and cast‑iron variants for lower‑cost milling operations.

Product Range and Specialties of Shandong Huamin Steel Ball Joint-stock CO,LTD.

The catalogue focuses on grinding media for ball mills, including forged steel balls sized from 20 mm to 150 mm and alloy‑steel variants such as Cr‑Mo B2/B3 grades. In the grinding‑media industry, forged steel balls are commonly supplied in hardness ranges of 60 - 65 HRC, spherical tolerance of ±0.02 mm and surface roughness Ra ≤ 0.8 µm. Typical grades include high‑carbon steel (often designated 100‑C), alloy steel (e.g., Cr‑Mo 12‑4‑3) and high‑chrome (B2/B3) which deliver wear resistance for hard‑ore grinding. Casting‑iron balls are usually supplied in grades 17 mm‑100 mm with manganese‑silicon alloys, though the current catalogue lists only steel media. Buyers also expect standard packaging in wooden crates or steel drums, with each crate holding 1 - 2 tonne of balls depending on size, and loading plans that fit 20‑ft or 40‑ft containers.

Trade and Export Information - Shandong Huamin Steel Ball Joint-stock CO,LTD.

China is a global exporter of grinding media, and Shandong province hosts several high‑capacity steel foundries that meet international demand. HS 7325.90 and 7325.91 cover forged steel balls, while HS 7326.11 applies to cast‑iron grinding media; customs authorities often require material safety data sheets and a certificate of origin for these codes. Major import markets for Chinese grinding media include North‑American mining firms, South‑American copper producers, European cement manufacturers and Asian power‑generation plants. Buyers typically request ISO 9001 compliance, SGS or Intertek inspection reports, and where applicable, CE marking for downstream equipment integration. Logistics commonly use FOB Shandong ports with subsequent ocean freight on 20‑ft or 40‑ft containers; bulk shipments may also be arranged as break‑bulk in wooden pallets for larger rod products.

Sourcing from Shandong Huamin Steel Ball Joint-stock CO,LTD. - Buyer Guidance

When sourcing grinding balls from this supplier, request a mill test report that details chemical composition (C, Cr, Mo percentages), hardness (HRC), and dimensional tolerance. Verify the supplier’s ISO 9001 and ISO 14001 certificates and ask for the latest third‑party inspection certificate covering the specific HS code of the ordered item. Confirm the size distribution chart for the batch, especially for ranges such as 40‑65 mm where tolerance windows affect mill efficiency. It is prudent to ask for a sample batch to run a pilot mill test before committing to a full‑scale order, and to clarify the packaging configuration (crate dimensions, moisture protection) to ensure compliance with container loading plans.

What diameters of grinding balls does Shandong Huamin offer?

The catalogue lists forged steel balls from 20 mm up to 150 mm, including specific sizes such as 25 mm, 40‑65 mm, 1‑3 inches (25‑75 mm) and larger 100‑150 mm balls for ore‑reduction applications.

Which material grades are included in the product list?

Materials include high‑carbon steel, alloy steel (Cr‑Mo and high‑chrome variants), and forged carbon steel classified as B2/B3 grade. Cast‑iron grades are mentioned in the description but not detailed in the current catalogue entries.

What HS codes apply to the grinding media?

Forged steel balls fall under HS 7325.90 or 7325.91, while cast‑iron grinding media use HS 7326.11. The high‑hardness steel grinding rods are classified under HS 7213.91.

Which certifications should a buyer verify?

The supplier lists ISO 9001:2000 and ISO 14001:2004 certifications. Buyers should also request a third‑party inspection report (e.g., SGS or Intertek) and a material test certificate for the specific HS code being purchased.

What are typical packaging and shipping methods?

Products are usually packed in wooden crates sized to hold 1 - 2 tonne per crate, suitable for loading into 20‑ft or 40‑ft containers. FOB Shandong port is the common Incoterm, with buyers arranging ocean freight to destinations such as the United States, Canada or Europe.

What documentation is needed for customs clearance?

Customs typically require a commercial invoice, packing list, certificate of origin, and the mill test report showing chemical composition and hardness. The relevant HS code must match the product description to avoid classification delays.

Are sample orders possible?

Yes, the supplier accepts sample requests; a small batch (e.g., 5 kg) can be sent for pilot testing, allowing the buyer to verify size tolerance, hardness and wear performance before scaling up.

What are common lead times for a full order?

Lead times depend on size and quantity but generally range from 30 to 45 days for forged steel balls, with additional time for inspection and documentation preparation.
