About Pingdingshan Dingjingxin Industry & Trade Co., Ltd. - Graphite Supplier in China

Pingdingshan Dingjingxin Industry & Trade Co., Ltd. operates in China, located in the Pingdingshan region, and currently lists nine active products across four top categories: Blocks, Tiles & Slabs; Graphite; Bearing; and Agriculture. The catalogue focuses on high‑purity graphite and related carbon‑based materials, with most items classified under HS chapter 38 (e.g., 3801.90 for graphite blocks, plates and rods) and a few under HS 8545.11 for graphite rotors and 8483.30 for graphite bearings. Each entry specifies the material composition, such as carbon purity of 99.5 % - 99.99 % for blocks and plates, or copper‑coated graphite powder with 10‑30 % copper content. The supplier’s product list therefore spans solid graphite components, coated powders and composite bearings designed for industrial applications.

The nine catalogue items include Isostatic Graphite Block, Graphite Plate for SPD Surge Protection Device, Molded Graphite Block, DJX Graphite Rotor, DJX Copper‑Coated Graphite Powder, Copper‑Coated Molybdenum Disulfide Powder, DJX Graphite Bearing, DJX Graphite Crucibles and DJX Graphite Rods. HS codes are provided for eight of these items, with the crucibles entry lacking a code in the source data. Materials range from synthetic pressed graphite (99.5 % - 99.9 % carbon) to metal‑graphite composites used in bearings, indicating a focus on high‑temperature and high‑conductivity applications.

Product Range and Specialties of Pingdingshan Dingjingxin Industry & Trade Co., Ltd.

The catalogue’s graphite products correspond to common industry grades such as ASTM D734‑type A (high‑purity synthetic graphite) and IEC 60384‑type C for molded blocks. Typical specifications for isostatic blocks include dimensional tolerances of ±0.1 mm, density around 1.70 g/cm³ and impurity limits below 0.01 % ash. Graphite plates used in surge protection devices are often produced to IEC 60673 standards, with surface roughness Ra < 0.8 µm and electrical resistivity below 0.01 Ω·cm. Copper‑coated graphite powders generally meet ISO 9001 quality management and are supplied with particle size distributions (e.g., D50 ≈ 10 µm) and copper coating thicknesses of 5‑30 µm. Bearings and rotors fabricated from carbon‑impregnated graphite or metal‑graphite composites typically adhere to ISO 15243 for dimensional accuracy and can operate at temperatures up to 1,200 °C.

Trade and Export Information - Pingdingshan Dingjingxin Industry & Trade Co., Ltd.

China is a leading exporter of graphite and carbon products, with Europe, North America and Southeast Asia representing the largest import markets for high‑purity graphite blocks, plates and powders. HS chapter 38 items (3801.90, 3801.20) are routinely inspected under the Chinese General Administration of Customs’ “Export Inspection and Quarantine” regime, requiring material safety data sheets (MSDS) and, where applicable, compliance with REACH or RoHS for metal‑coated powders. Graphite rotors (HS 8545.11) and bearings (HS 8483.30) are classified as electrical machinery components and often demand IEC 60204 safety certifications and ISO 9001 quality system evidence. Typical logistics involve loading 20‑ft or 40‑ft containers with wooden crates or bulk bags, moisture‑proof liners, and using Incoterms such as FOB Shanghai or CIF Los Angeles. Buyers commonly request pre‑shipment inspection reports and conformity certificates to meet the import regulations of their destination countries.

Sourcing from Pingdingshan Dingjingxin Industry & Trade Co., Ltd. - Buyer Guidance

When sourcing graphite blocks or plates from this supplier, request a detailed test report covering carbon purity (ICP‑AES), ash content, bulk density and dimensional tolerance. For copper‑coated powders, ask for particle size analysis (laser diffraction), copper coating percentage (EDX) and compliance documents for REACH or RoHS if the end market requires it. Verify that the supplier can provide ISO 9001 (and optionally ISO 14001) certificates, as these are standard benchmarks for graphite manufacturers. Prior to placing a large order, obtain a sample batch and confirm packaging integrity - typically double‑wall wooden crates for blocks and sealed metal drums for powders - to avoid moisture uptake during transit.

What graphite products does Pingdingshan Dingjingxin list in its catalogue?

The catalogue includes Isostatic Graphite Blocks, Graphite Plates for SPD surge protection, Molded Graphite Blocks, Graphite Rotors (HS 8545.11), Copper‑Coated Graphite Powder, Copper‑Coated Molybdenum Disulfide Powder, Graphite Bearings, Graphite Crucibles and Graphite Rods.

Which HS codes are associated with the listed graphite items?

Most graphite items use HS 3801.90 (e.g., blocks, plates, rods), the copper‑coated powder uses HS 3801.20, the rotor uses HS 8545.11 and the bearing uses HS 8483.30. The crucibles entry does not provide an HS code in the source data.

What purity levels are typical for the supplier’s graphite blocks?

The blocks are specified as high‑purity graphite with carbon content ranging from 99.5 % to 99.99 %, matching industry grades such as ASTM D734‑type A.

Are any certifications available for these products?

The facts do not list any certifications held by the supplier. Buyers should request ISO 9001 quality‑management certification and, where applicable, REACH or RoHS compliance documents for metal‑coated powders.

What are common packaging methods for graphite blocks and powders?

Blocks are usually packed in double‑wall wooden crates with moisture‑barrier liners; powders are typically sealed in metal drums or bulk bags with inner liners to prevent contamination.

What are typical lead times and minimum order quantities for graphite products?

Lead times in the graphite industry range from 4 weeks for standard blocks to 6‑8 weeks for custom‑size or coated powders. Minimum order quantities often start at one 20‑ft container (approximately 15‑20 tons) for bulk graphite blocks, while powders may have MOQ of 500 kg depending on coating specifications.

Which markets commonly import Chinese graphite products like those listed?

European Union countries, United States, Japan and South Korea are major importers of high‑purity graphite blocks and powders, especially for electronics, aerospace and battery manufacturing.

What documentation should a buyer request before shipment?

Buyers should request a material test report (purity, ash, density), MSDS, any applicable ISO certificates, and a pre‑shipment inspection certificate issued by Chinese customs authorities.
