## Common questions

**What does this company make?** Jiushun GPC recarburizer / carbon raiser is produced from petroleum coke by high-temperature graphitization (~2,800 °C). Standard grades ZW01–ZW04 list fixed carbon from ≥98.0% to ≥99.0%, sulfur (sulphur) ≤0.05%, and nitrogen 100–300 ppm. Particle sizes include 0–2 mm, 1–5 mm (most requested), 3–5 mm and 5–8 mm; other sizes on request.

**What other names do buyers use?** Buyers search the same product as graphitized petroleum coke, graphite petroleum coke, GPC, recarburizer, recarburiser, carbon raiser, carbon additive or carburizer. Jiushun’s published fully graphitized grades are ZW01–ZW04; semi-graphitized grades are ZWS01–ZWS03.

**What sulfur level is on the sheet?** All four Jiushun ZW grades list sulfur at ≤0.05% (low sulfur / low sulphur) on the factory specification sheet. Confirm the contractual maximum on the purchase order and COA.

**What nitrogen levels are listed?** On the Jiushun factory sheet, nitrogen is listed as 100 ppm (ZW01), 200 ppm (ZW02 and ZW03), and 300 ppm (ZW04). Buyers specifying ductile iron often request a nitrogen ceiling in writing before shipment.

**How fast do they reply?** We reply on the next business day (China Standard Time, UTC+8) by email and WhatsApp after we receive grade, particle size and quantity.

**What about U.S. import duty?** U.S. landed duty for graphitized petroleum coke depends on the HTS classification used for the shipment and on the importer’s declared use. Jiushun does not publish a fixed U.S. duty percentage. Confirm classification with your customs broker before the commercial invoice is final.
