HS Code for Green petroleum coke

Green petroleum coke is classified under HS code 2713.11, which is the specific designation for petroleum coke that has not been calcined. This material is a byproduct of the oil refining process, specifically from the thermal cracking of heavy residual oils in a coker unit. The term "green" is a technical industry descriptor indicating that the coke is in its raw form, containing a significant percentage of volatile matter, typically ranging from 8% to 15%. Under the Harmonized System, Chapter 27 covers mineral fuels and mineral oils. Heading 2713 is dedicated to petroleum coke, petroleum bitumen, and other residues of petroleum oils. The classification under 2713.11 is determined by the absence of the calcination process, which is a secondary heat treatment used to remove volatile hydrocarbons and increase the carbon purity of the coke. Customs authorities rely on laboratory analysis of the volatile matter and moisture content to verify that the product has not been calcined, as calcined petroleum coke is classified separately under 2713.12. This distinction is vital because green coke is often used as a fuel or as a feedstock for calcining, whereas calcined coke is primarily used in the production of anodes for aluminum smelting. The classification is governed by GRI 1, as the subheading text for 2713.11 explicitly provides for the non-calcined state.

Products Included

• Raw petroleum coke
• Sponge coke (not calcined)
• Needle coke (not calcined)
• Shot coke (not calcined)
• Fluid petroleum coke

Common Misclassification

The most common misclassification occurs with calcined petroleum coke, which is classified under HS code 2713.12. Importers often fail to distinguish between the two, despite the significant difference in value and industrial application. Another error involves classifying green coke as bituminous coal under 2701.12. While both are carbonaceous fuels, petroleum coke is a residue of oil refining, whereas coal is a naturally occurring mineral, placing them in entirely different headings within Chapter 27.

FAQ

What is the HS code for green petroleum coke?

The HS code for green petroleum coke is 2713.11, representing petroleum coke that is not calcined.

How is green coke distinguished from calcined coke for customs?

Distinction is made based on volatile matter content; green coke typically has over 8% volatiles, while calcined coke has less than 2%.
