About Sungraf Material Group Limited - Graphite Supplier in China

Sungraf Material Group Limited operates out of China and currently lists 22 distinct graphite‑related products in its catalogue. The portfolio covers flexible graphite paper, expandable graphite powders, natural flake graphite in bulk and powder form, micropowder graphite for lubrication, graphite electrodes, reinforced graphite sheets and other specialty forms. Each entry is identified with its HS code, ranging from 2504 for natural graphite products to 3801 for expandable and isostatic graphite, and 6815 for flexible graphite sheets and yarn.

The supplier’s top categories are Graphite, Carbon and Electrodes, reflecting a focus on high‑purity carbon materials. Products such as the Flexible Graphite Rolls (HS 2504.90) specify carbon content of 99.5 % +, while the EAF Graphite Electrodes (HS 8545.11) use petroleum needle‑coke based graphite with a minimum of 99.5 % carbon. Expandable Graphite powders (HS 3801.90) are described with fixed carbon contents between 85 % and 99.9 % and are marketed for high‑temperature applications.

Product Range and Specialties of Sungraf Material Group Limited

The catalogue includes Flexible Graphite Paper to Spread Heat (HS 6815.10) made from natural expanded graphite with 95‑99 % carbon, several grades of Natural Flake Graphite (HS 2504.10/2504.90) in bulk, powder and micron‑sized forms, Micropowder Graphite for lubrication (HS 2504.10) with 90‑99.9 % carbon, and EAF Graphite Electrodes (HS 8545.11) based on petroleum needle coke. Additional items are reinforced graphite sheets (HS 3801.20/3801.90) and isostatic graphite blocks (HS 3801.90) with purity up to 99.9 %. In the graphite industry, natural flake graphite is typically graded by fixed carbon content (90‑99 %) and particle size (e.g., 45 µm‑500 µm). Expandable graphite is classified by expansion temperature (200‑400 °C) and bulk density, while flexible graphite sheets are measured by thickness (0.1‑2 mm) and tensile strength (10‑30 MPa). Buyers often request ISO 9001 quality management certification, REACH compliance, and SGS test reports for carbon content, moisture and ash levels.

Trade and Export Information - Sungraf Material Group Limited

China is one of the world’s largest exporters of graphite products, supplying Europe, North America, Japan, South Korea and Southeast Asia. HS Chapter 25 (2504) covers natural graphite and its powders, Chapter 38 (3801) covers expandable and isostatic graphite, Chapter 68 (6815) covers flexible graphite sheets and yarn, and Chapter 85 (8545) covers graphite electrodes. Importers typically require material safety data sheets (MSDS), conformity to ISO 9001 and ISO 14001, and, for aerospace or battery applications, additional certifications such as IEC 62660 for battery‑grade spherical graphite. Standard export packaging includes 20‑ft or 40‑ft containers fitted with bulk bags (25 kg‑1 ton) for powders and wooden crates for sheets, with FOB or CIF incoterms most commonly used. Chinese graphite exporters must comply with customs inspection under the China‑EU Generalised Scheme (CEGS) and the U.S. Customs and Border Protection (CBP) import requirements for hazardous materials when applicable.

Sourcing from Sungraf Material Group Limited - Buyer Guidance

When sourcing graphite from this supplier, buyers should request a recent laboratory analysis confirming fixed carbon content, moisture, ash and particle‑size distribution for each product grade. Test reports should be issued by an accredited third‑party laboratory such as SGS or Intertek. Verify that the supplier can provide REACH and RoHS declarations, especially for products destined for electronics or battery manufacturing. Typical minimum order quantities range from 1 metric ton for bulk powders to 500 kg for flexible sheets, with lead times of 4‑6 weeks after order confirmation and receipt of a pro‑forma invoice.

What HS codes are associated with the graphite products listed by Sungraf Material Group Limited?

The catalogue uses HS 2504.10 and 2504.90 for natural flake graphite and its powders, HS 3801.90 for expandable and isostatic graphite, HS 6815.10 for flexible graphite paper, rolls and yarn, and HS 8545.11 for EAF graphite electrodes.

What carbon purity levels are typical for the Flexible Graphite Rolls and the EAF Graphite Electrodes?

Flexible Graphite Rolls are specified with a carbon content of 99.5 % + and the EAF Graphite Electrodes require a minimum of 99.5 % carbon, both meeting high‑purity standards for industrial applications.

Which certifications should a buyer request before purchasing expandable graphite powder?

Buyers should ask for ISO 9001 quality management certification, REACH compliance, and an SGS or Intertek test report that details fixed carbon content (85‑99.9 %), expansion temperature and moisture level.

What are the typical packaging formats for the graphite powders offered by this supplier?

Graphite powders are usually packed in multi‑wall paper bags or bulk bags ranging from 25 kg to 1 ton, sealed to protect against moisture, and loaded into 20‑ft or 40‑ft containers for shipment.

Which markets commonly import Chinese graphite products like those listed here?

Major import markets include the European Union, the United States, Japan, South Korea and the emerging battery manufacturers in Southeast Asia.

What documentation is required for customs clearance of graphite sheets classified under HS 6815.10?

Customs typically require a commercial invoice, packing list, certificate of origin, and a material safety data sheet (MSDS) that confirms the graphite content and any hazardous classifications.
