2713.90.00.00 - Other residues of petroleum oils or of oils obtained from bituminous materials

This HTS category, 2713.90.00.00, encompasses "Other residues of petroleum oils or of oils obtained from bituminous materials." It serves as a residual classification for products derived from the distillation or processing of petroleum oils and bituminous substances that are not specifically accounted for in other subheadings within heading 2713. These residues typically arise as byproducts from refining operations and can vary significantly in their physical and chemical properties.

Crucially, this category distinguishes itself from its siblings by excluding petroleum coke and petroleum bitumen. Petroleum coke, classified under 2713.11.00.00 through 2713.12.00.00, is a solid carbonaceous material produced during petroleum refining. Petroleum bitumen, found under 2713.20.00.00, is a semi-solid or solid material which is black or brownish-black and possesses adhesive qualities. Therefore, 2713.90.00.00 is for those residual materials that do not fit the specific definitions of coke or bitumen.

As this is a leaf node, there are no further subcategories within 2713.90.00.00. Classification into this subheading relies on the determination that a residue is indeed derived from petroleum oils or bituminous materials and does not meet the criteria for petroleum coke or petroleum bitumen. Examples might include certain types of heavy oils, sludge, or amorphous residues that are not otherwise classified. The classification will depend on the specific composition and characteristics of the material in question.
