About Linzhang County Hengqiang Carbon Co., Ltd - Electrodes Supplier in China

Linzhang County Hengqiang Carbon Co., Ltd is based in Linzhang County, China and lists six active products. The catalogue covers both electrode and graphite product lines, including various graphite electrodes and related components. Products are classified under HS code families 3801, 8545 and 6815, reflecting artificial graphite nipples, needle‑coke based electrodes and expanded graphite crucibles. The company’s top categories are Electrodes and Graphite, indicating a focus on high‑purity carbon materials. Each product description includes material specifications such as carbon content thresholds of 99.5 % to 99.9 %.

The six items comprise a Nipple Graphite Electrode Nipple (HS 3801.20, pitch‑based artificial graphite with ≥ 99.9 % carbon), three variants of Graphite Electrode (HS 8545.11) differentiated by binder type and ash content, an Oxidation Resistance Graphite Ring (HS 6815.10, flexible expanded graphite ≥ 99 % carbon), a Graphite Crucible (HS 6815.10, high‑purity graphite ≥ 99.5 % carbon) and a UHP Graphite Electrode (HS 8545.11, ultra‑high‑purity carbon with low ash). The catalogue therefore spans electrode nipples, standard and high‑performance electrodes, as well as crucibles and rings used in high‑temperature industrial processes.

Product Range and Specialties of Linzhang County Hengqiang Carbon Co., Ltd

The product range includes artificial graphite electrode nipples, needle‑coke based and petroleum‑coke bound graphite electrodes, ultra‑high‑purity (UHP) electrodes, oxidation‑resistant graphite rings, and high‑purity graphite crucibles. In the graphite electrode market, buyers typically specify carbon content above 99.5 % and ash content below 0.5 %, with grades such as standard, high‑performance (HP) and ultra‑high‑purity (UHP) defined by IEC 61861 and ASTM A997. Graphite nipples are often used as current collectors in electric arc furnaces and are supplied to meet IEC 60287 dimensional tolerances. Crucibles and rings made from expanded or high‑purity graphite are commonly required to withstand temperatures above 3000 °C and are graded by thermal shock resistance and bulk density (usually 1.7 - 1.9 g/cm³). Buyers in steelmaking, aluminum smelting and battery sectors look for these specifications when selecting graphite components.

Trade and Export Information - Linzhang County Hengqiang Carbon Co., Ltd

China is a major exporter of graphite electrodes and related carbon products, supplying steel producers in Europe, Southeast Asia and the Middle East. The HS code 8545.11 for graphite electrodes is regularly inspected under the Chinese customs export control system, and shipments are often accompanied by a Certificate of Origin and a test report confirming carbon content, ash, and bulk density. The HS code 3801.20 for graphite nipples and 6815.10 for crucibles and rings fall under the broader Chapter 38 and Chapter 68 categories, which may be subject to anti‑dumping duties in certain jurisdictions.

Typical export logistics involve loading 20‑ft or 40‑ft containers with wooden crates or steel drums, depending on product size, and using Incoterms FOB or CIF to major ports such as Shanghai or Tianjin. Buyers usually require compliance with ISO 9001 quality management and may request additional certifications such as ISO 14001 environmental management or CE marking for equipment destined for the EU. Inspection agencies like SGS or Bureau Veritas frequently perform pre‑shipment sampling to verify the specified carbon purity and mechanical strength of electrodes and crucibles.

Sourcing from Linzhang County Hengqiang Carbon Co., Ltd - Buyer Guidance

When sourcing graphite electrodes or crucibles from Linzhang County Hengqiang Carbon Co., Ltd, buyers should obtain a detailed material test report that lists carbon content, ash percentage, bulk density, and thermal shock resistance. Requesting certification copies for ISO 9001 or ISO 14001, if held, helps verify the supplier’s quality management system; otherwise, buyers can ask the supplier to arrange third‑party testing before shipment. Samples of the UHP electrode or crucible in standard dimensions (e.g., 25 mm diameter, 150 mm length) allow verification of dimensional tolerances and surface finish. Confirm the packaging format - typically wooden crates with internal cushioning - to ensure safe transport, and clarify the preferred Incoterm and lead time, which for graphite electrodes is commonly 30 - 45 days after order confirmation.

What types of graphite electrodes are listed by the supplier?

The catalogue includes a standard Graphite Electrode (hp) based on needle coke, a petroleum‑coke bound Graphite Electrode (rp), and an ultra‑high‑purity (UHP) Graphite Electrode, all classified under HS 8545.11 with carbon contents ranging from > 99.5 % to ≥ 99.9 %.

Which HS codes apply to the supplier’s graphite products?

Graphite electrodes use HS 8545.11, the Nipple Graphite Electrode Nipple is under HS 3801.20, and both the Oxidation Resistance Graphite Ring and Graphite Crucible fall under HS 6815.10.

What quality specifications are typical for these graphite electrodes?

Buyers usually require carbon purity above 99.5 %, ash content below 0.5 %, bulk density around 1.7 - 1.9 g/cm³, and compliance with IEC 61861 or ASTM A997 standards for dimensions and mechanical strength.

Are there common certifications buyers should request?

While the supplier’s certifications are not listed, buyers often request ISO 9001 for quality management, ISO 14001 for environmental control, and a third‑party test report confirming the material specifications.

What is a typical minimum order quantity and lead time?

For standard graphite electrodes and crucibles, minimum orders are often measured in multiples of 20‑ft containers (approximately 1,000 kg per container), with a lead time of 30 - 45 days after order confirmation; smaller sample orders can be arranged on request.

How are the products packaged for export?

Graphite electrodes and nipples are usually packed in wooden crates with internal cushioning to prevent breakage, while crucibles and rings may be placed in steel drums or reinforced cartons; all packaging complies with ISPM 15 regulations for wood packaging.

Which markets typically import these Chinese graphite products?

Major importers include steel manufacturers in Europe, aluminum smelters in the Middle East, and battery component makers in Southeast Asia, all of which rely on the high‑temperature resistance and electrical conductivity of Chinese graphite electrodes and crucibles.
