Calcined petroleum coke Hs Code

Calcined petroleum coke harmonized system code

Product Overview Calcined petroleum coke (CPC), classified under HS Code 271312, is a high-purity carbonaceous material derived from the thermal processing of green petroleum coke. This product undergoes a calcination process at temperatures typically ranging from 1,200°C to 1,350°C, resulting in reduced volatile matter and enhanced electrical conductivity. Physically, CPC is characterized by its granular or lumpy form with a fixed carbon content generally exceeding 97%, low sulfur content (commonly below 1%), and minimal moisture levels (under 0.5%). The HS Code 271312 encompasses several subcategories, including anode-grade, fuel-grade, and needle coke, each differentiated by their density, sulfur content, and impurity levels. CPC’s primary applications span the aluminum smelting industry, graphite electrode manufacturing, and steel production, where its high carbon content and structural integrity are critical. Its value proposition lies in superior thermal stability, low ash content, and consistent chemical composition, making it an indispensable raw material in metallurgical and chemical processing sectors. HS Code Classification & Trade Specifications The Harmonized System (HS) Code 271312 is structured as follows: Chapter 27 (Mineral Fuels, Mineral Oils and Products of their Distillation), Heading 2713 (Petroleum coke, petroleum bitumen and other residues of petroleum oils), and Subheading 271312 (Calcined petroleum coke). This classification is based on the product’s origin, processing method (calcination), and physicochemical properties, distinguishing it from raw or non-calcined petroleum coke. Trade practices typically involve packaging CPC in bulk bags, steel drums, or bulk shipment via sealed containers to prevent contamination and moisture ingress. Preservation methods prioritize dry storage conditions to maintain quality parameters such as fixed carbon content (>97%), sulfur content (<1%), and ash content (<0.5%). Compliance with international quality standards, including ISO 9001 and relevant ASTM specifications, is critical for customs clearance and trade documentation. This classification and detailed product specification ensure alignment with WTO guidelines and facilitate accurate tariff application and regulatory adherence in global markets.

Calcined petroleum coke Chapter Note

1.- This Chapter does not cover : (a) Separate chemically defined organic compounds, other than pure methane and propane which are to be classified in heading 27.11; (b) Medicaments of heading 30.03 or 30.04; or (c) Mixed unsaturated hydrocarbons of heading 33.01, 33.02 or 38.05. 2.- References in heading 27.10 to “petroleum oils and oils obtained from bituminous minerals” include not only petroleum oils and oils obtained from bituminous minerals but also similar oils, as well as those consisting mainly of mixed unsaturated hydrocarbons, obtained by any process, provided that the weight of the non-aromatic constituents exceeds that of the aromatic constituents. However, the references do not include liquid synthetic polyolefins of which less than 60 % by volume distils at 300 C, after conversion to 1,013 millibars when a reduced-pressure distillation method is used (Chapter 39). 3.- For the purposes of heading 27.10, “waste oils” means waste containing mainly petroleum oils and oils obtained from bituminous minerals (as described in Note 2 to this Chapter), whether or not mixed with water. These include : (a) Such oils no longer fit for use as primary products (for example, used lubricating oils, used hydraulic oils and used transformer oils); (b) Sludge oils from the storage tanks of petroleum oils, mainly containing such oils and a high concentration of additives (for example, chemicals) used in the manufacture of the primary products; and (c) Such oils in the form of emulsions in water or mixtures with water, such as those resulting from oil spills, storage tank washings, or from the use of cutting oils for machining operations.
