GPC carbon raiser for Mexico
Lingshou Jiushun supplies graphitized petroleum coke recarburizer / carbon raiser ZW01–ZW04 for Mexico-bound procurement. Sulfur is ≤0.05% on the sheet; nitrogen and particle size are locked on the purchase order and COA.
ZW grades buyers compare
| Grade | F.C. min | S max | Ash max | V.M. max | Moisture max | N |
|---|---|---|---|---|---|---|
| ZW01 | ≥99.0% | ≤0.05% | ≤0.5% | ≤0.5% | ≤0.50% | 100 ppm |
| ZW02 | ≥98.5% | ≤0.05% | ≤0.6% | ≤0.9% | ≤0.50% | 200 ppm |
| ZW03 | ≥98.5% | ≤0.05% | ≤0.7% | ≤0.8% | ≤0.50% | 200 ppm |
| ZW04 | ≥98.0% | ≤0.05% | ≤1.0% | ≤1.0% | ≤0.50% | 300 ppm |

Questions procurement asks
- Do you provide documents for Mexican import clearance?
- Commercial invoice, packing list and COA fields are prepared for the shipment. Importer-of-record classifications remain the buyer’s responsibility.
- 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 should Mexico buyers specify an order?
- Include company, grade (or nitrogen ceiling), particle size, quantity in MT, destination and preferred Incoterms.
