Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If uncalcined green coke
Green petroleum coke before calcination falls under the uncalcined subheading.
If roasted for battery electrodes
Specially roasted petroleum coke for electrodes may classify as roasted iron ore agglomerates if processed differently.
If when formed into carbon refractory shapes
Calcined coke shaped into refractories moves to Chapter 69 for manufactured refractory products.

Import Tips & Compliance
• Require supplier certificates showing metals content (V, Ni <300 ppm) typical for anode-grade material
• Verify calcination temperature records (>1250°C) to distinguish from uncalcined green coke
• Bulk shipments require proper stowage to prevent contamination; use dedicated holds for carbon materials
